[PMID: 36657541 DOI: 10.1016/j.ijbiomac.2023.123283] [Citation(s) in RCA: 18] [Impact Index Per Article: 18.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/08/2022] [Revised: 12/28/2022] [Accepted: 01/11/2023] [Indexed: 01/19/2023]
Abstract
Hydrogels have emerged as a versatile platform for a numerous biomedical application due to their ability to absorb a huge quantity of biofluids. In order to design hydrogels, natural polymers are an attractive option owing to their biocompatibility and biodegradability. Due to abundance in occurrence, cost effectiveness, and facile crosslinking approaches, alginate has been extensively investigated to fabricate hydrogel matrix. Management of cancer and chronic wounds have always been a challenge for pharmaceutical and healthcare sector. In both cases, curcumin have been shown significant improvement and effectiveness. However, the innate restraints like poor bioavailability, hydrophobicity, and rapid systemic clearance associated with curcumin have restricted its clinical translations. The current review explores the cascade of research around curcumin encapsulated alginate hydrogel matrix for wound healing and cancer therapy. The focus of the review is to emphasize the mechanistic effects of curcumin with its fate inside the cells. Further, the review discusses different approaches to designed curcumin loaded alginate hydrogels along with the parameters that regulates their release behavior. Finally, the review is concluded with emphasize on some key aspect on increasing the efficacy of these hydrogels along with novel strategies to further develop curcumin loaded alginate hydrogel matrix with multifacet applications.

Blood-brain barrier-penetrating single CRISPR-Cas9 nanocapsules for effective and safe glioblastoma gene therapy. SCIENCE ADVANCES 2022; 8:eabm8011. [PMID: 35442747 PMCID: PMC9020780 DOI: 10.1126/sciadv.abm8011] [Citation(s) in RCA: 73] [Impact Index Per Article: 36.5] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/13/2021] [Accepted: 03/02/2022] [Indexed: 05/15/2023]
Abstract
We designed a unique nanocapsule for efficient single CRISPR-Cas9 capsuling, noninvasive brain delivery and tumor cell targeting, demonstrating an effective and safe strategy for glioblastoma gene therapy. Our CRISPR-Cas9 nanocapsules can be simply fabricated by encapsulating the single Cas9/sgRNA complex within a glutathione-sensitive polymer shell incorporating a dual-action ligand that facilitates BBB penetration, tumor cell targeting, and Cas9/sgRNA selective release. Our encapsulating nanocapsules evidenced promising glioblastoma tissue targeting that led to high PLK1 gene editing efficiency in a brain tumor (up to 38.1%) with negligible (less than 0.5%) off-target gene editing in high-risk tissues. Treatment with nanocapsules extended median survival time (68 days versus 24 days in nonfunctional sgRNA-treated mice). Our new CRISPR-Cas9 delivery system thus addresses various delivery challenges to demonstrate safe and tumor-specific delivery of gene editing Cas9 ribonucleoprotein for improved glioblastoma treatment that may potentially be therapeutically useful in other brain diseases.

Abstract
The parallel development of reversible deactivation radical polymerization and click reaction concepts significantly enriches the toolbox of synthetic polymer chemistry. The synergistic effect of combining these approaches manifests itself in a growth of interest to the design of well-defined functional polymers and their controlled conjugation with biomolecules, drugs, and inorganic surfaces. In this review, we discuss the results obtained with reversible addition-fragmentation chain transfer (RAFT) polymerization and different types of click reactions on low- and high-molar-mass reactants. Our classification of literature sources is based on the typical structure of macromolecules produced by the RAFT technique. The review addresses click reactions, immediate or preceded by a modification of another type, on the leaving and stabilizing groups inherited by a growing macromolecule from the chain transfer agent, as well as on the side groups coming from monomers entering the polymerization process. Architecture and self-assembling properties of the resulting polymers are briefly discussed with regard to their potential functional applications, which include drug delivery, protein recognition, anti-fouling and anti-corrosion coatings, the compatibilization of polymer blends, the modification of fillers to increase their dispersibility in polymer matrices, etc.

Abstract
Graphene possesses a large specific surface area, a high Young's modulus, high fracture strength, high electrical conductivity, and excellent optical performance. It has been widely studied for biomedical use since its first appearance in the literature. This article offers an overview of the latest advances in the design of graphene-based materials for delivery of bioactive agents. To enhance the translation of these carriers into practical use, the toxicity involved is needed to be examined in future research in more detail. In addition, guidelines for standardizing experimental conditions during the evaluation of the performance of graphene-based materials are required to be established so that candidates showing higher practical potential can be more effectively identified for further development. This can streamline the optimization and use of graphene-based materials in delivery applications.

Abstract
We synthesized a series of poly(disulfide)s by ring-opening polymerization and demonstrated that the copolymerization of monomer 1 containing diethylenetriamine moieties and monomer 2 containing guanidyl ligands could generate an efficient delivery platform for different forms of CRISPR-Cas9-based genome editors, including plasmid, mRNA, and protein. The excellent delivery performance of designed poly(disulfide)s stems from their delicate molecular structures to interact with genome-editing biomacromolecules, unique delivery pathways to mediate the cellular uptake of CRISPR-Cas9 cargoes, and strong ability to escape the endosome. The degradation of poly(disulfide)s by intracellular glutathione not only promotes the timely release of CRISPR-Cas9 machineries into the cytosol but also minimizes the cytotoxicity that nondegradable polymeric carriers often encounter. These merits collectively account for the excellent ability of poly(disulfide)s to mediate different forms of CRISPR-Cas9 for their efficient genome-editing activities in vitro and in vivo.

Abstract
OBJECTIVES The aim of this study was to couple fused deposition modelling 3D printing with melt extrusion technology to produce core-shell-structured controlled-release tablets with dual-mechanism drug-release performance in a simulated intestinal fluid medium. Coupling abovementioned technologies for personalized drug delivery can improve access to complex dosage formulations at a reasonable cost. Compared with traditional pharmaceutical manufacturing, this should facilitate the following: (1) the ability to manipulate drug release by adjusting structures, (2) enhanced solubility and bioavailability of poorly water-soluble drugs and (3) on-demand production of more complex structured dosages for personalized treatment. METHODS Acetaminophen was the model drug and the extrusion process was evaluated by a series of physicochemical characterizations. The geometries, morphologies, and in vitro drug-release performances were compared between directly compressed and 3D-printed tablets. KEY FINDINGS Initially, 3D-printed tablets released acetaminophen more rapidly than directly compressed tablets. Drug release became constant and steady after a pre-determined time. Thus, rapid effectiveness was ensured by an initially fast acetaminophen release and an extended therapeutic effect was achieved by stabilizing drug release. CONCLUSIONS The favourable drug-release profiles of 3D-printed tablets demonstrated the advantage of coupling HME with 3D printing technology to produce personalized dosage formulations.

Abstract
In the last few years, various chemical bondings and interactions were rationally adopted to develop different multilayered microcapsules, where the empty interior accommodated various important cargoes, including bioactive molecules, nanoparticles, antibodies, enzymes, etc., and the thin membrane protected/controlled the release of the loaded cargo. Eventually, such materials are with immense potential for a wide range of prospective applications related to targeted drug delivery, sensing, bio-imaging, developing biomimetic microreactors, and so on. The emphasis on the use of various chemistries for the development of functional and useful microcapsules is rarely illustrated in the literature in the past. In this feature article, the rational uses of different chemistries for (a) preparing and (b) post-modifying various functional microcapsules are accounted. The appropriate selection of chemical bondings/interactions, including electrostatic interaction, host-guest interaction, hydrogen bonding, and covalent bonding, allowed the integration of essential constituents during the layer-by-layer deposition process for 'in situ' tailoring of the relevant and diverse properties of the hollow microcapsules. Recently, different chemically reactive hollow microcapsules were also introduced through the strategic association of 'click chemistry', ring-opening azlactone reaction, thiol-ene reaction, and 1,4-conjugate addition reaction for facile and desired post covalent modifications of the multilayer membrane. The strategic selection of chemistry remained as the key basis to synthesize smart and useful microcapsules.

Abstract
Hydrogels serving as a drug carrier was realized by entrapping small-sized drug molecules within their cross-linked interstitial networks. After covering the targeted location, hydrogels interact with the physiological fluids and swell, resulting in an increased interspace between networks for the outside diffusion of drugs. However, inevitable in vivo inflammatory responses or bacterial infection on the implant materials and persistent cargo release are still challenging. Herein, we report the fabrication of dual-responsive hydrogels based on acid-sensitive poly(ethylenimine) (PEI) derivative (PEI(-COOH/-vinyl)), thiol-responsive camptothecin prodrug monomer (CPTM), and hydrophilic oligo(ethylene glycol) methyl ether acrylate (OEGMA) by a conventional radical polymerization. Curcumin was then solubilized into the hydrogels to endow them with antimicrobial and cancer resistance properties. The in vitro experiments exhibited sustained hydrogel dissolution and CPT release in a simulated physiological environment. The antimicrobial and cytotoxicity tests of drug-loaded hydrogels using methicillin-resistant Staphylococcus aureus (MRSA) strains and HeLa cancer cell lines, respectively, indicated that the hydrogels possessed efficient antimicrobial effects and could successfully inhibit the growth of cancer cells.

Abstract
Antibiotic resistance and the colonization of resistant bacteria such as Staphylococcus aureus on surfaces, often in the form of biofilms, prolong hospitalization periods and increase mortality, thus is a significant concern for healthcare providers. To prevent biofilm formation, the inadequate concentration of using nanoparticles as antibacterial coating agents is one of the major obstacles. This study aimed to design a hypervalency TiO2 nanocomposite as a reserved base to carry a high amount of active antibacterial agents such as lysostaphin via a biotin-streptavidin-biotin bridge. The utilization of the streptavidin-biotin system could increase the abundance of lysostaphin. Lysostaphin was expressed in Escherichia coli and purified. Both recombinant lysostaphin and titanium oxide nanocomposite were conjugated with biotin and linked to a streptavidin bridge. The kinetics and activity of the enzyme were examined after each step utilizing N-acetylhexaglycine as a substrate. Physical characteristics of nanoparticles containing lysostaphin were determined using AFM, SEM, FTIR, and zeta potential. The results showed changes in size, charge, and morphology of the nanoparticles following the lysostaphin attachment. Also, the stability and kinetics of the active biological enzymes on nanoparticles were reexamined following 8 months of storage. Exploiting this approach, various biotinylated antibacterial agents could be prepared and rapidly immobilized on a nanoparticle as an active net against related infectious agents.

Abstract
Theranostics refers to the incorporation of therapeutic and diagnostic functions into one material system. An important class of nanomaterials exploited for theranostics is metal nanoclusters (NCs). In contrast to gold and silver NCs, copper is an essential trace element for humans. It can be more easily removed from the body. This, along with the low cost of copper that offers potential large-scale nanotechnology applications, means that copper NCs have attracted great interest in recent years. The latest advances in the design, synthesis, surface engineering, and applications of copper NCs in disease diagnosis, monitoring, and treatment are reviewed. Strategies to control and enhance the emission of copper NCs are considered. With this synopsis of the up-to-date development of copper NCs as theranostic agents, it is hoped that insights and directions for translating current advances from the laboratory to the clinic can be further advanced and accelerated.

Abstract
BACKGROUND The conventional dosage forms cannot be administered to all patients because of interindividual variability found among people of different race coupled with different metabolism and cultural necessities. Therefore, to address this global issue there is a growing focus on the fabrication of new drug delivery systems customised to individual needs. Medicinal products printed using 3-D technology are transforming the current medicine business to a plausible alternative of conventional medicines. METHODS The PubMed database and Google scholar were browsed by keywords of 3-D printing, drug delivery, and personalised medicine. The data about techniques employed in the manufacturing of 3-D printed medicines and the application of 3-D printing technology in the fabrication of individualised medicine were collected, analysed and discussed. RESULTS Numerous techniques can fabricate 3-D printed medicines however, printing-based inkjet, nozzle-based deposition and laser-based writing systems are the most popular 3-D printing methods which have been employed successfully in the development of tablets, polypills, implants, solutions, nanoparticles, targeted and topical dug delivery. In addition, the approval of Spritam® containing levetiracetam by FDA as the primary 3-D printed drug product has boosted its importance. However, some drawbacks such as suitability of manufacturing techniques and the available excipients for 3-D printing need to be addressed to ensure simple, feasible, reliable and reproducible 3-D printed fabrication. CONCLUSION 3-D printing is a revolutionary in pharmaceutical technology to cater the present and future needs of individualised medicines. Nonetheless, more investigations are required on its manufacturing aspects in terms cost effectiveness, reproducibility and bio-equivalence.

Abstract
Nanodrug delivery systems are considered as promising therapeutic platforms to convey drugs to tumor cells. In this study, a single layer of carboxymethylcellulose (CMC) and poly N-vinylpyrrolidone (PVP) was cross-linked through disulfide bond and deposited on graphene oxide nanoparticles (GO NPs) using layer-by-layer technique. Overexpression of folate receptors on tumor cells is a great hallmark for drug delivery systems; though the NPs were functionalized by monoclonal folic acid antibody (FA) using polyethylene glycol (PEG) as linker. The mean diameter of synthesized nanoparticles was 60 nm. Curcumin was encapsulated within CMC layer with high encapsulation capacity of 94%. In vitro investigation showed 87% curcumin release at simulated tumor environment. Curcumin loaded FA modified CMC/PVP GO NPs showed high inhibition of 76 and 81% against Saos2 and MCF7 cell lines in vitro. In vivo investigations on 4T1 bearing breast cancer mice model exhibited 76% antitumor efficiency via active targeting mechanism of folate mediated transport without any significant side effect. Immunohistochemistry and immunofluorescence analyses showed enhanced antiangiogenesis, apoptosis and tumor growth inhibition.

Abstract
In the past 40 years, the nanoparticle drug delivery system for tumor peptide vaccines has been widely studied which also reached a splendid result. Nanomaterial can enhance the targeting of vaccines, help vaccines enter the cells and trigger immune response by themselves. They also help in increasing cellular uptake, improving permeability and efficacy. Currently, several categories of nanopreparation, such as liposome, polymeric micelle, polymeric nanoparticle, gold nanoparticle and so on, are proved that they are appropriate for peptide vaccines. This review we discussed the possible mechanisms of nanomaterial's action on the regulation of immunological functions and several major applications of this advanced drug delivery system for tumor peptide vaccine.

Abstract
Disulfide-crosslinked hollow polyelectrolyte microcapsules composed of thiolated chitosan (CS-SH) and hyaluronic acid (HA-SH) were prepared by combining the layer-by-layer (LBL) technique and horseradish peroxidase (HRP)-mediated oxidative cross-linking reaction in mild conditions. FITC-dextran-doped CaCO3 microspheres were used as template core and removed after LBL depositing CS-SH and HA-SH on the surface. The disulfide-crosslinked (CS/HA) microcapsules were readily fabricated by HRP-mediated oxidative coupling of the thiol groups in CS/HA shell layer in the presence of HRP (10 units/mL) and Tyramine hydrochloride (Tyr, 35 mmol/L). The kinetics of enzymatic disulfide-crosslinking reaction was investigated through the real-time monitoring of the consumption of thiol groups by UV absorption spectra. It found that the formation of disulfide linkages by the enzymatic thiol oxidation reaction showed a gradual acceleration. The disulfide-crosslinked CS/HA hydrogel were rapidly formed in gelation time between approximately 17 and 30 min, which were dependent on the concentrations of HRP and Tyr. The disulfide linkages endowed the microcapsule-enhanced physical stability and low permeability under physiological conditions and redox-responsive degradability in reducing environments. The structural stability of disulfide-crosslinked (CS/HA) microcapsules was visualized by confocal laser scanning microscopy in phosphate-buffered saline containing 5.0 mmol/L dithiothreitol (DTT) to evaluate the redox-responsive disassembly process. Redox-responsive controlled release of encapsulated FITC-dextran from the disulfide-crosslinked (CS/HA) microcapsules were obtained. The release profiles of FITC-dextran could be manipulated by controlling the shell thickness and the concentration of DTT. The conformational stability analyses and more than 94% esterase activity of released bovine serum albumin (BSA) from (CS/HA) microcapsules conformed that the structural integrity and bioactivity were well preserved during the encapsulation and release process. The microcapsules exhibited excellent cytocompatibility for HEK 293 cells up to a concentration of 1.0 mg/mL. The microcapsules efficiently delivered loaded FITC-BSA into HeLa cells and released the protein in the reducing cytosol. This study proposed a novel approach for producing disulfide-crosslinked microcarriers for intracellular delivery and redox-responsive controlled release of protein.

Abstract
Drugs delivered by proper carriers enter into the cells much more rapidly and carry out their action much more promptly than in the free forms. A high drug concentration can be sustained for longer periods of time at the target site in the cell. In in vivo conditions, this would translate into a reduction of systemic toxicity, dosage and frequency of dosing. Dendritic polymers significantly affect drug delivery in terms of reaching the target site, modifying the bio-distribution of the drug, and enhancing the efficacy of different drugs including anticancer compounds. 2-({[2-({[(2-tolyl)amino]carbonothioyl}oxy)ethyl]amino}carbo-nyl)benzoic acid 1 is a thiocarbamate derivative belonging to an already reported class of non-nucleoside HIV-1 reverse transcriptase inhibitors. In in vitro assay it showed no cytotoxic effects but was endowed with very low solubility and poor activity against wild-type HIV-1 (EC50 = 27 μM). With the aim at improving its water solubility, 1 has been successfully incorporated inside non-toxic amino acids-modified core-shell hetero dendrimers. IR, NMR, zeta potential, mean size of particles, buffer capacity and in vitro release profile of prepared materials were reported. All dendriplexes were evaluated in cell-based assays to assess their cytotoxic profile. The obtained complexes, which harmonize a peripheral polycationic character and a buffer capacity which presuppose efficient cells penetration and increased residence time with a not PAMAM structured biodegradable scaffold, were well water-soluble and could rationally appear as a promising set of prodrugs for safe in vivo administrations.

Abstract
A bioapplicable cargo delivery system requires the following characteristics of biocompatibility, in vivo stability, and selective cargo release at target sites. We introduce herein the microcapsules enclosed with a single-layered shell of gold nanoparticles (AuNPs) mutually connected by an amyloidogenic protein of α-synuclein (αS). The microcapsules were fabricated by producing oil(chloroform)-in-water Pickering emulsions of the αS-encapsulated AuNPs and subsequent molecular engagement of the outlying αS molecules, leading to formidable β-sheet formation in the presence of chloroform. The wrinkled skin of microcapsules obtained after evaporation of the internal chloroform also reflects robustness of the protein-protein interaction, which was experimentally confirmed by their rheological stability. For the emulsions loaded with rhodamine 6G, their dye release was demonstrated to be controlled by proteases. Along with their photothermal activity, the AuNP-containing microcapsules and their proteolyzed fragments were therefore suggested to be capable of eliminating aberrant cells in the protease-activated pathologically affected areas. Orthogonal cargo loading was also achieved by encapsulating both hydrophobic and hydrophilic substances either directly dissolved in chloroform or prepackaged in inverted micelles, respectively. Microcapsule's functionality was further expanded by localizing quantum dots, magnetic nanoparticles, and antibodies inside or on the surface of the microcapsules. Taken together, these multimodal AuNP microcapsules are suggested to be an ideal cargo carrier system, which could be employed in not only biomedical theranostic applications as they exhibit structural robustness, specific targeting, triggered release, and photothermal activity but also sensor development in general.

Abstract
Cyclodextrins (CDs) are naturally occurring cyclic oligosaccharides bearing a basket-shaped topology with an "inner-outer" amphiphilic character. The abundance of hydroxyl groups enables CDs to be functionalized with multiple targeting ligands and imaging elements. The imaging time, and the payload of different imaging elements, can be tuned by taking advantage of the commercial availability of CDs with different sizes of the cavity. This review aims to offer an outlook of the chemistry and engineering of CDs for the development of molecular probes. Complexation thermodynamics of CDs, and the corresponding implications for probe design, are also presented with examples demonstrating the structural and physiochemical roles played by CDs in the full ambit of molecular imaging. We hope that this review not only offers a synopsis of the current development of CD-based molecular probes, but can also facilitate translation of the incremental advancements from the laboratory to real biomedical applications by illuminating opportunities and challenges for future research.

Abstract
Layer-by-layer fabrication of three dimensional (3D) objects from digital models is called 3D printing. This technology established just about three decades ago at the confluence of materials science, chemistry, robotics, and optics researches to ease the fabrication of UV-cured resin prototypes. The 3D technology was rapidly considered as a standard instrument in the aerospace, automotive, and consumer goods production factories. Nowadays, research interests in the 3D printed products have been raised and achieved ever-increasing traction in the pharmaceutical industry; so that, the first 3D printed drug product was approved by FDA in August 2015. This editorial summarizes the competitive advantages of the 3D printing for the made-on-demand, personalized and complex products, manufacturing of which establish opportunities for enhancing the accessibility, effectiveness, and safety of drugs.

Abstract
Cancer immunotherapy has recently shown dramatic clinical success inducing durable response in patients of a wide variety of malignancies. Further improvement of the clinical outcome with immune related cancer treatment requests more exquisite manipulation of a patient's immune system with increased immunity against diseases while mitigating the toxicities. To meet this challenge, biomaterials applied to immunoengineering are being developed to achieve tissue- and/or cell-specific immunomodulation and thus could potentially enhance both the efficacy and safety of current cancer immunotherapies. Here, we review the recent advancement in the field of immunoengineering using biomaterials and their applications in promoting different modalities of cancer immunotherapies, with focus on cell-, antibody-, immunomodulator-, and gene-based immune related treatments and their combinations with conventional therapies. Challenges and opportunities are discussed in applying biomaterials engineering strategies in the development of future cancer immunotherapies.

Abstract
The objective of this study was to develop a new approach for fabrication of zero order release of active pharmaceutical ingredients (APIs) using hot-melt extrusion (HME) and 3D printing technology to generate tablets with specific 3D structures. By correlating the geometry of the 3D printed tablets with their dissolution and drug release rates, mathematical models that have been developed to describe drug release mechanisms were also studied. Acetaminophen was used as a model drug, and Benecel™ hydroxypropyl methylcellulose (HPMC) E5 and Soluplus® were used to formulate nine fuse depositional 3D-printed tablets with different inner core fill densities and outside shell thicknesses. This work reports the successful fabrication of solid-dispersion filaments with an API dispersed in HPMC based matrix via HME technology, and the production of zero order controlled release tablets with different 3D structures (tablets #3, 5, 6, and 9) using a 3D printer.

Abstract
Avidin-biotin interaction is one of the strongest non-covalent interactions in the nature. Avidin and its analogues have therefore been extensively utilized as probes and affinity matrices for a wide variety of applications in biochemical assays, diagnosis, affinity purification, and drug delivery. Recently, there has been a growing interest in exploring this non-covalent interaction in nanoscale drug delivery systems for pharmaceutical agents, including small molecules, proteins, vaccines, monoclonal antibodies, and nucleic acids. Particularly, the ease of fabrication without losing the chemical and biological properties of the coupled moieties makes the avidin-biotin system a versatile platform for nanotechnology. In addition, avidin-based nanoparticles have been investigated as diagnostic systems for various tumors and surface antigens. In this review, we will highlight the various fabrication principles and biomedical applications of avidin-based nanoparticles in drug delivery and diagnosis. The structures and biochemical properties of avidin, biotin and their respective analogues will also be discussed.

Abstract
In order to specifically deliver drugs into cancer cells with targeted recognition and controlled release, biocompatible hollow mesoporous silica nanocarriers with tumor-targeting and glutathione-responsive release dual properties were developed. These multifunctional nanocarriers were fabricated by anchoring transferrin on the surface of hollow mesoporous silica nanoparticles through disulfide bond conjugation, which could be cleaved in the presence of glutathione. In this case, transferrin acted as the gatekeeper to control the drug release, and as a tumor-targeting agent to improve drug accumulation at the tumor site simultaneously. The detailed investigations indicate that the anticancer drug (doxorubicin) release from the nanocarriers was strongly dependent on the concentration of glutathione. The capacity of the nanocarriers to selectively deliver doxorubicin to the tumor cells was demonstrated in vitro and in vivo. The doxorubicin-loaded nanocarriers showed enhanced inhibition of tumor growth and minimal side-effects in vivo compared to free doxorubicin. These redox stimuli-responsive nanocarriers that achieved a combination of tumor targeting and controlled drug release provide a promising platform for efficient cancer therapies.

Abstract
Common chemotherapy is often associated with adverse effects in normal cells and tissues. As an alternative approach, localized chemotherapy can diminish the toxicity of systemic chemotherapy while providing a sustained release of the chemotherapeutics at the target tumor site. Therefore, injectable biodegradable hydrogels as drug delivery systems for chemotherapeutics have become a matter of importance. Here, we review the application of a variety of injectable hydrogel-based drug delivery systems, including thermosensitive, pH-sensitive, photosensitive, dual-sensitive, as well as active targeting hydrogels, for the treatment of different types of cancer. Generally, injectable hydrogel-based drug delivery systems are found to be more efficacious than the conventional systemic chemotherapy in terms of cancer treatment.

Abstract
With the unprecedented progresses of biomedical nanotechnology during the past few decades, conventional drug delivery systems (DDSs) have been involved into smart DDSs with stimuli-responsive characteristics. Benefiting from the response to specific internal or external triggers, those well-defined nanoplatforms can increase the drug targeting efficacy, in the meantime, reduce side effects/toxicities of payloads, which are key factors for improving patient compliance. In academic field, variety of smart DDSs have been abundantly demonstrated for various intriguing systems, such as stimuli-responsive polymeric nanoparticles, liposomes, metals/metal oxides, and exosomes. However, these nanoplatforms are lack of standardized manufacturing method, toxicity assessment experience, and clear relevance between the pre-clinical and clinical studies, resulting in the huge difficulties to obtain regulatory and ethics approval. Therefore, such relatively complex stimulus-sensitive nano-DDSs are not currently approved for clinical use. In this review, we highlight the recent advances of smart nanoplatforms for targeting drug delivery. Furthermore, the clinical translation obstacles faced by these smart nanoplatforms have been reviewed and discussed. We also present the future directions and perspectives of stimuli-sensitive DDS in clinical applications.

Abstract
Gene therapies represent a promising therapeutic route for liver cancers, but major challenges remain in the design of safe and efficient gene-targeting delivery systems. For example, cationic polymers show good transfection efficiency as gene carriers, but are hindered by cytotoxicity and non-specific targeting. Here we report a versatile method of one-step conjugation of glycyrrhetinic acid (GA) to reduce cytotoxicity and improve the cultured liver cell -targeting capability of cationic polymers. We have explored a series of cationic polymer derivatives by coupling different ratios of GA to polypropylenimine (PPI) dendrimer. These new gene carriers (GA-PPI dendrimer) were systematically characterized by UV-vis,(1)H NMR titration, electron microscopy, zeta potential, dynamic light-scattering, gel electrophoresis, confocal microscopy and flow cytometry. We demonstrate that GA-PPI dendrimers can efficiently load and protect pDNA, via formation of nanostructured GA-PPI/pDNA polyplexes. With optimal GA substitution degree (6.31%), GA-PPI dendrimers deliver higher liver cell transfection efficiency (43.5% vs 22.3%) and lower cytotoxicity (94.3% vs 62.5%, cell viability) than the commercial bench-mark DNA carrier bPEI (25 kDa) with cultured liver model cells (HepG2). There results suggest that our new GA-PPI dendrimer are a promising candidate gene carrier for targeted liver cancer therapy.

Abstract
A template synthesis allows the preparation of monodisperse nanoparticles with high reproducibility and independent from self-assembly requirements. Tailor-made polymer cages were used for the preparation of nanoparticles, which were made of cross-linked macromolecules with pendant thiol groups. Gold nanoparticles (AuNPs) were prepared in the polymer cages in situ, by using different amounts of cages versus gold. The polymer cages exhibited a certain capacity, below which the AuNPs could be grown with excellent control over the size and shape. Control experiments with a linear diblock copolymer showed a continuous increase in the AuNP size as the gold feed increased. This completely different behavior regarding the AuNP size evolution was attributed to the flexibility of the polymer chain depending on cross-linking. Moreover, the polymer cages were suitable for the encapsulation of AgNPs, PdNPs, and PtNPs by the in situ method.

Abstract
Shape and responsiveness of nanoengineered delivery carriers are crucial characteristics for rapid and efficient delivery of therapeutics. We report on a novel type of micrometer-sized hydrogel particles of controlled shape with dual pH- and redox-sensitivity for intracellular delivery of anticancer drugs. The cubical and spherical poly(methacrylic acid) (PMAA) networks with disulfide links are obtained by cross-linking PMAA with cystamine within hydrogen-bonded multilayers of PMAA/poly(vinylpyrrolidone) (PMAA/PVPON) on sacrificial mesoporous templates. The pH-triggered hydrogel swelling/shrinkage not only affords effective doxorubicin entrapment but also efficient endosomal/lysosomal escape, and redox-triggered degradation provides drug release into the cytosolic space. The hydrogels degrade rapidly to low molecular weight chains in the presence of the typical intracellular concentration of glutathione, which should ensure a rapid renal clearance in vivo. Particle shape is found to affect internalization at the initial step of cell-particle interactions. Drug-loaded spherical particles are found to be 12% more cytotoxic than the corresponding cubes within the first 10 h of cell incubation suggesting more rapid internalization of spheres. Both doxorubicin-loaded hydrogel cubes and spheres demonstrate 50% and 90% cytotoxicity when incubated with HeLa cancer cells for 24 and 48 h, respectively. The presented approach integrates the advantages of pH-sensitivity, enzymatic degradation, and shape-regulated internalization for novel types of "intelligent" three-dimensional networks with programmable behavior for use in controlled delivery of therapeutics.

Abstract
Formation of both mechanically durable and programmably degradable layer-by-layer (LbL) films in a biocompatible fashion has potential applications in cell therapy, tissue engineering, and drug-delivery systems, where the films are interfaced with living cells. In this work, we developed a simple but versatile method for generating in situ cross-linked and responsively degradable LbL films, based on the thiol-exchange reaction, under highly cytocompatible conditions (aqueous solution at pH 7.4 and room temperature). The cytocompatibility of the processes was confirmed by coating individual yeast cells with the cross-linked LbL films and breaking the films on demand, while maintaining the cell viability. In addition, the processes were applied to the controlled release of an anticancer drug in the HeLa cells.

Abstract
There is ample evidence that biodegradable polyelectrolyte nanocapsules are multifunctional vehicles which can smuggle drugs into cells, and release them upon endogenous activation. A large number of endogenous stimuli have already been tested in vitro, and in vivo research is escalating. Thus, the interest in the design of intelligent polyelectrolyte multilayer (PEM) drug delivery systems is clear. The need of the hour is a systematic translation of PEM-based drug delivery systems from the lab to clinical studies. Reviews on multifarious stimuli that can trigger the release of drugs from such systems already exist. This review summarizes the available literature, with emphasis on the recent progress in PEM-based drug delivery systems that are receptive in the presence of endogenous stimuli, including enzymes, glucose, glutathione, pH, and temperature, and addresses different active and passive drug targeting strategies. Insights into the current knowledge on the diversified endogenous approaches and methodological challenges may bring inspiration to resolve issues that currently bottleneck the successful implementation of polyelectrolytes into the catalog of third-generation drug delivery systems.

Abstract
Engineered particles adsorb biomolecules (e.g., proteins) when introduced in a biological medium to form a layer called a "corona". Coronas, in particular the protein corona, play an important role in determining the surface properties of particles and their targeting abilities. This study examines the influence of protein coronas on the targeting ability of layer-by-layer (LbL)-assembled polymer capsules and core-shell particles functionalized with monoclonal antibodies. Upon exposure of humanized A33 monoclonal antibody (huA33 mAb)-functionalized poly(methacrylic acid) (PMA) capsules or huA33 mAb-PMA particles to human serum, a total of 83 or 65 proteins were identified in the protein coronas, respectively. Human serum of varying concentrations altered the composition of the protein corona. The antibody-driven specific cell membrane binding was qualitatively and quantitatively assessed by flow cytometry and fluorescence microscopy in both the absence and presence of a protein corona. The findings show that although different protein coronas formed in human serum (at different concentrations), the targeting ability of both the huA33 mAb-functionalized PMA capsules and particles toward human colon cancer cells was retained, demonstrating no significant difference compared with capsules and particles in the absence of protein coronas: ∼70% and ∼90% A33-expressing cells were targeted by the huA33 mAb-PMA capsules and particles, respectively, in a mixed cell population. This result demonstrates that the formation of protein coronas did not significantly influence the targeting ability of antibody-functionalized LbL-polymer carriers, indicating that the surface functionality of engineered particles in the presence of protein coronas can be preserved.

The development of thin macromolecular layers with incorporated disulfide bonds that can be disrupted and formed again under redox stimulation is of general interest for drug release applications, because such layers can provide rapid and reversible responses to specific biological systems and signals. However, the preparation of such layers from polythiols remains difficult, because of the fast oxidation of thiol groups in ambient conditions. Here we propose water-soluble thiolactone-containing copolymers as stable precursors containing protected thiol groups, allowing us to produce on demand polythiol layers on gold substrates in the presence of amine derivatives. Electrochemical, water contact angle, X-ray photoelectron spectroscopy, and X-ray reflectometry measurements evidence the formation of uniform copolymer layers containing both anchored and free thiol groups. The number of free thiols increases with the content of thiolactone units in the copolymers. In a second step, a thiolated dye, used as a model drug, was successfully grafted on the free thiol groups through disulfide bonds using mild oxidizing conditions, as proved by fluorescence and quartz crystal microbalance measurements. Finally, the reversible release/regrafting of the dye under redox stimulation is demonstrated.

Abstract
Tannic acid (TA)-based multilayer assemblies have attracted increasing interest for biomedical applications. Here we explore properties of TA-poly(N-vinylpyrrolidone) (TA-PVPON) hydrogen-bonded multilayers for drug encapsulation and long-term storage. We demonstrate that the small molecular weight anticancer drug, doxorubicin (DOX), can be successfully loaded into (TA-PVPON) capsules with high encapsulation efficiency. We have also found that the encapsulated DOX can be efficiently stored inside the capsules for the pH range from pH = 7.4 to pH = 5. We show that the chemical and functional stability of TA at neutral and basic pH values is achieved through complexation with PVPON. The UV-vis spectrophotometry and in situ ellipsometry analyses of the hydrogen bonding interactions between TA and PVPON at different pH values reveal pH-dependent behavior of TA-PVPON capsules for the pH range from pH = 7.4 to pH = 5. Increasing deposition pH value from pH = 5 to pH = 7.4 leads to a 2-fold decrease in capsule thickness. However, this trend is reversed when salt concentration of the deposition solutions is increased from 0.01 M to 0.1 M NaCl. We have also demonstrated that the permeability of (TA-PVPON) capsules prepared using low salt deposition conditions and pH = 7.4 can be increased 2-fold by exposure of the capsules to 0.1 M NaCl salt solutions at the same pH. Our work opens new perspectives for design of novel polymer carriers for controlled drug delivery in cancer therapy.

Abstract
Biconcave discoidal silica microcapsules were fabricated by reaction of tetraethoxysilane (TEOS) on biconcave discoidal Ca(OH)2 templates, followed by core removal. The biconcave discoidal morphology of microcapsules was characterized by confocal laser scanning microscopy (CLSM) and transmission electron microscopy (TEM). The thickness of silica capsule shell can be tuned by two methods, "Gradient concentration" method and "Multi-step growth" method. Through the latter one, the shell thickness can be controlled more effectively. Compared with spherical microcapsules, the biconcave discoidal ones were internalized into smooth muscle cells (SMCs) with a slower rate.

Abstract
Drug delivery from 3-dimensional (3D) structures is a rapidly growing area of research. It is essential to achieve structures wherein drug stability is ensured, the drug loading capacity is appropriate and the desired controlled release profile can be attained. Attention must also be paid to the development of appropriate fabrication machinery that allows 3D drug delivery systems (DDS) to be produced in a simple, reliable and reproducible manner. The range of fabrication methods currently being used to form 3D DDSs include electrospinning (solution and melt), wet-spinning and printing (3-dimensional). The use of these techniques enables production of DDSs from the macro-scale down to the nano-scale. This article reviews progress in these fabrication techniques to form DDSs that possess desirable drug delivery kinetics for a wide range of applications.

Abstract
Heterotelechelic, hydrophilic polymers with a primary amine and thiol group at the α- and ω-chain end, respectively, are synthesized via reversible addition-fragmentation chain transfer (RAFT) polymerization in a straightforward and versatile way and subsequently used for the design of dual-responsive polymer/gold nanohybrids. Therefore, a phthalimido-containing chain transfer agent (CTA) is synthesized and used for the polymerization of the hydrophilic monomers N-isopropylacrylamide (NIPAM) and N,N-dimethylacrylamide (DMA). After polymerization, the trithiocarbonate functionality at the ω-chain end, originating from the CTA, is converted into a thiol upon aminolysis. In the next step, the phthalimido α-chain end is hydrolyzed into a primary amine, resulting in heterotelechelic, hydrophilic polymers. End-group conversions are monitored by (1)H NMR spectroscopy, MALDI-TOF MS analysis, and UV-Vis spectroscopy, confirming that quantitative modifications are obtained during each stage. The amino groups of these heterotelechelic polymer chains are modified with citraconic anhydride, after which the obtained polymers are grafted with the thiol group onto citrate-stabilized gold nanoparticles resulting in the creation of dual-temperature- and pH-responsive gold particles.

Abstract
Nanotechnology represents an area of particular promise and significant opportunity across multiple scientific disciplines. Ongoing nanotechnology research ranges from the characterization of nanoparticles and nanomaterials to the analysis and processing of experimental data seeking correlations between nanoparticles and their functionalities and side effects. Due to their special properties, nanoparticles are suitable for cellular-level diagnostics and therapy, offering numerous applications in medicine, e.g. development of biomedical devices, tissue repair, drug delivery systems and biosensors. In nanomedicine, recent studies are producing large amounts of structural and property data, highlighting the role for computational approaches in information management. While in vitro and in vivo assays are expensive, the cost of computing is falling. Furthermore, improvements in the accuracy of computational methods (e.g. data mining, knowledge discovery, modeling and simulation) have enabled effective tools to automate the extraction, management and storage of these vast data volumes. Since this information is widely distributed, one major issue is how to locate and access data where it resides (which also poses data-sharing limitations). The novel discipline of nanoinformatics addresses the information challenges related to nanotechnology research. In this paper, we summarize the needs and challenges in the field and present an overview of extant initiatives and efforts.

Abstract
Ribavirin (RBV), a broad-spectrum antiviral agent, is a standard medication against hepatitis C virus (HCV). However, despite the decades of clinical success, the mechanism of action of this drug against HCV remains a subject of debate. Furthermore, the appeal of this therapeutic agent is considerably lessened by unfavorable pharmacokinetics. This interdisciplinary study contributes to the understanding of intracellular effects exerted by RBV and presents a successful design of macromolecular prodrugs of RBV to achieve a safer treatment. Specifically, we demonstrate that RBV exhibits a pronounced anti-inflammatory activity in cultured macrophages as is evidenced by a 2-fold decrease in the levels of produced nitric oxide achieved using a clinically relevant concentration of this drug. However, this effect was characterized by a rather narrow therapeutic window with experimental values of EC50 and IC50 being 7 and 19 μM, respectively. Macromolecular prodrugs were obtained using an acrylate derivative of RBV, RAFT polymerization technique, and N-vinyl pyrrolidone as a partner monomer. The synthesized polymers were characterized with uniform molecular weights, relatively narrow polydispersities, and gradually increasing content of RBV. The resulting polymer therapeutics were effective in delivering their payload to the cultured macrophages and afforded a significantly wider therapeutic window, as much as >1000 μM (18-fold in relative values). Taken together, this work contributes significantly to the development of safer methods for delivery of RBV, as well as understanding the mechanism of action and origins of the side effects of this broad-spectrum antiviral agent.
