Abstract
Advances in nanotechnology have generated a broad range of nanoparticles (NPs) for numerous biomedical applications. Among the various properties of NPs are functionalities being related to thiol substructures. Numerous biological processes that are mediated by cysteine or cystine subunits of proteins representing the workhorses of the bodies can be transferred to NPs. This review focuses on the interface between thiol chemistry and NPs. Pros and cons of different techniques for thiolation of NPs are discussed. Furthermore, the various functionalities gained by thiolation are highlighted. These include overall bio- and mucoadhesive, cellular uptake enhancing, and permeation enhancing properties. Drugs being either covalently attached to thiolated NPs via disulfide bonds or being entrapped in thiolated polymeric NPs that are stabilized via inter- and intrachain crosslinking can be released at the diseased tissue or in target cells under reducing conditions. Moreover, drugs, targeting ligands, biological analytes, and enzymes bearing thiol substructures can be immobilized on noble metal NPs and quantum dots for therapeutic, theranostic, diagnostic, biosensing, and analytical reasons. Within this review a concise summary and analysis of the current knowledge, future directions, and potential clinical use of thiolated NPs are provided.

Abstract
Delivery systems that can encapsulate a precise amount of drug and offer a spatiotemporally controlled drug release are being actively sought for safe yet effective cancer therapy. Compared to polymer nanoparticle (NP)-based delivery systems that rely on physical drug encapsulation, NPs derived from stimuli-sensitive covalent polymer-drug conjugates (PDCs) have emerged as promising alternatives offering precise control over drug dosage and spatiotemporal drug release. Herein, we report a reduction-sensitive PDC "Dex-SS-PTXL" synthesized by conjugating dextran and paclitaxel (PTXL) through a disulfide bond-bearing linker. The synthesized Dex-SS-PTXL PDC with a precise degree of substitution in terms of the percentage of repeat units of dextran covalently conjugated to PTXL (27 ± 0.6%) and the amount of drug carried by the PDC (39 ± 1.4 wt %) was found to self-assemble into spherical NPs with an average size of 110 ± 34 nm and a ζ-potential of -14.09 ± 8 mV. The reduction-sensitive Dex-SS-PTXL NPs were found to release PTXL exclusively in response to the reducing agent concentration reflective of the intracellular reducing environment of the tumor cells. Challenging BT-549 and MCF-7 cells with Dex-SS-PTXL NPs revealed significant cytotoxicity, while the IC50 values and the mode of action (mitotic arrest) of Dex-SS-PTXL NPs were found to be comparable to those of free PTXL, highlighting the active nature of the intracellularly released drug. The developed PDC with its unique ability to self-assemble into NPs and stimuli-responsive drug release can enhance the success of the NP-based drug delivery systems during clinical translation.

Abstract
Polylysine and materials that integrate lysine form promising drug delivery platforms. As a cationic macromolecule, a polylysine polymer electrostatically interacts with cells and is efficiently internalized, thereby enabling intracellular delivery. Although polylysine is intrinsically pH-responsive, the conjugation with different functional groups imparts smart, stimuli-responsive traits by adding pH-, temperature-, hypoxia-, redox-, and enzyme-responsive features for enhanced delivery of therapeutic agents. Because of such characteristics, polylysine has been used to deliver various cargos such as small-molecule drugs, genes, proteins, and imaging agents. Furthermore, modifying contrast agents with polylysine has been shown to improve performance, including increasing cellular uptake and stability. In this review, the use of lysine residues, peptides, and polymers in various drug delivery systems has been discussed comprehensively to provide insight into the design and robust manufacturing of lysine-based delivery platforms.

Abstract
Self-assembled nanostructures that are sensitive to environmental stimuli are promising nanomaterials for drug delivery. In this class, disulfide-containing redox-sensitive strategies have gained enormous attention because of their wide applicability and simplicity of nanoparticle design. In the context of nucleic acid delivery, numerous disulfide-based materials have been designed by relying on covalent or noncovalent interactions. In this review, we highlight major advances in the design of disulfide-containing materials for nucleic acid encapsulation, including covalent nucleic acid conjugates, viral vectors or virus-like particles, dendrimers, peptides, polymers, lipids, hydrogels, inorganic nanoparticles, and nucleic acid nanostructures. Our discussion will focus on the context of the design of materials and their impact on addressing the current shortcomings in the intracellular delivery of nucleic acids.

Abstract
Microfluidic flow-directed self-assembly of biological stimuli-responsive block copolymers is demonstrated with dual-location cleavable linkages at the junction between hydrophilic and hydrophobic blocks and on pendant group within the hydrophobic blocks. On-chip self-assembly within a two-phase microfluidic reactor forms various "DualM" polymer nanoparticles (PNPs), including cylinders and multicompartment vesicles, with sizes and morphologies that are tunable with manufacturing flow rate. Complex kinetically trapped intermediates between shear-dependent states provide the most detailed mechanism to date of microfluidic PNP formation in the presence of flow-variable high shear. Glutathione (GSH)-triggered changes in PNP size and internal structure depend strongly on the initial flow-directed size and internal structure. Upon incubation in GSH, flow-directed PNPs with smaller average sizes showed a faster hydrodynamic size increase (attributed to junction cleavage) and those with higher excess Gibbs free energy showed faster inner compartment growth (attributed to pendant cleavage). These results demonstrate that the combination of chemical control of the location of biologically responsive linkages with microfluidic shear processing offers promising routes for tunable "smart" polymeric nanomedicines.

Abstract
To maximize drug targeting to solid tumors, cancer nanomedicines with prolonged circulation times are required. To this end, poly(ethylene glycol) (PEG) has been widely used as a steric shield of nanomedicine surfaces to minimize serum protein absorption (opsonisation) and subsequent recognition and clearance by cells of the mononuclear phagocyte system (MPS). However, PEG also inhibits interactions of nanomedicines with target cancer cells, limiting the effective drug dose that can be reached within the target tumor. To overcome this dilemma, nanomedicines with stimuli-responsive cleavable PEG functionality have been developed. These benefit from both long circulation lifetimes en route to the targeted tumor as well as efficient drug delivery to target cancer cells. In this review, various stimuli-responsive strategies to dePEGylate nanomedicines within the tumor microenvironment will be critically reviewed.

Abstract
To prolong the circulation time of drug, PEGylation has been widely used via the enhanced permeability and retention (EPR) effect, thereby providing new hope for better treatment. However, PEGylation also brings the "PEG dilemma", which is difficult for the cellular absorption of drugs and subsequent endosomal escape. As a result, the activity of drugs is inevitably lost after PEG modification. To achieve successful drug delivery for effective treatment, the crucial issue associated with the use of PEG-lipids, that is, “PEG dilemma” must be addressed. In this paper, we introduced the development and application of nanocarriers with cleavable PEGylation, and discussed various strategies for overcoming the PEG dilemma. Compared to the traditional ones, the vehicle systems with different environmental-sensitive PEG-lipids were discussed, which cleavage can be achieved in response to the intracellular as well as the tumor microenvironment. This smart cleavable PEGylation provides us an efficient strategy to overcome “PEG dilemma”, thereby may be a good candidate for the cancer treatment in future.

Abstract
In this study, redox/ATP switchable theranostic nanoparticles (TNs) with precise specificity and controllable mobility were developed for the real-time monitoring of the release of an anticancer drug. A fluorescent probe (FAM) and a quencher (BHQ-1) were covalently conjugated to one end of an adenosine-5'-triphosphate (ATP) aptamer and its complementary DNA (cDNA), respectively. Then, doxorubicin (DOX) was intercalated within the DNA duplex to form a stable physical conjugate (FBA@DOX). Poly(ethylene glycol)-block-poly (aspartic acid-graft-cystamine) (PAS), a glutathione-sensitive cationic polymer, was synthesized and complexed with the FBA@DOX, endowing it with excellent stability in physiological solutions. Fluorescence recovery/quenching, DNase degradation, in vitro drug release, cellular uptake, and intracellular trafficking results revealed that the TNs remained in the "OFF" state, with a minimal FAM fluorescent signal and negligible DOX premature release, in low-glutathione and/or low-ATP environments. In contrast, the TNs turned "ON" and rapidly released FBA@DOX in glutathione-rich environments after internalization in cancer cells. The intracellular ATP triggered the conformational changes in FBA@DOX, thereby enabling the controlled release of DOX and simultaneous recovery of the fluorescence for monitoring the DOX release. In a cytotoxicity and apoptosis study, the redox/ATP switchable TNs demonstrated strong anticancer effects, attributable to their selective release of the drug. Overall, our findings may offer a promising strategy for developing a new generation of "smart" theranostic platforms.

The principle objective of this study was to develop and characterize redox responsive polymeric nanoparticles (PNPs) as a stimuli responsive drug delivery system. The chitosan-cystamine-methoxy poly(ethylene glycol) (CH-SS-mPEG) copolymer was synthesized by conjugation of cystamine appended chitosan with carboxylic acid-terminated mPEG and characterized by FTIR, 1H NMR, XRD analysis and colorimetric assay. This copolymer could be formulated as 5-Fluorouracil (5-FU) loaded PNPs and the characteristics of PNPs were evaluated. Moreover, folic acid functionalized PNPs were prepared for folate receptor targeted drug delivery. Drug release studies indicated that the redox sensitive PNPs were stable in physiological condition while quickly releasing 5-FU in the trigger of redox potential due to the cleavage of the disulfide linkages. In contrast, less quantity of drug was released from the reduction insensitive chitosan-g-methoxy poly(ethylene glycol) (CH-g-mPEG) based PNPs under both reduction sensitive and non-reductive conditions. From the cytotoxicity studies, it was evident that 5-FU loaded PNPs had higher toxicity against MCF7 cells when compared to 5-FU free PNPs. Subsequently, cellular uptake studies showed significantly increased internalization of folic acid attached PNPs. In conclusion, the developed PNPs appeared to be of great promise in redox responsive drug release for targeted drug delivery.

Abstract
PEGylation in polymeric nanomedicine has gained substantial predominance in biomedical applications due to its resistance to protein absorption, which is critically important for a therapeutic delivery system in blood circulation. The shielding layer of PEGylation, however, creates significant steric hindrance that negatively impacts cellular uptake and intracellular distribution at the target site. This unexpected effect compromises the biological efficacy of the encapsulated payload. To address this issue, one of the key strategies is to tether the disulfide bond to PEG for constructing a disulfide-bridged cleavable PEGylation. The reversible disulfide bond can be cleaved to enable selective PEG detachment. This article provides an overview on the strategy, method and progress of PEGylation nanosystem with the cleavable disulfide bond.

Abstract
An oral delivery system intended for treatment of colon cancer in HT29 cancerous cells was investigated by encapsulating hSET1 antisense and SN38 anticancer in nanoparticles based on cysteine trimethyl chitosan (cysTMC) and carboxymethyl dextran (CMD). Studies have shown hSET1 as the main type of histone methyltransferase (HMT) complex, is significantly overexpressed in malignant cells. In this study, hSET1 antisense was employed to inhibit gene expression. Additionally, SN38 was incorporated into nanoparticles to enhance the efficiency of the system by inhibition of topoisomerase 1. CysTMC was synthetized and characterized by (1)H NMR and FTIR. Nanoparticles were prepared through complexation of CMD and cysTMC. Particle size and surface charge was 100-150 nm and 17-21 mV respectively with drug content of around 2.6%. Gel electrophoresis assay proved the stability of antisense in simulated gastric and intestinal fluids. Nanoparticles showed high mucoadhesion and glutathione responsive release. Cellular uptake was observed by confocal microscopy and quantified by flow cytometry. Cytotoxicity of NPs was assessed using MTT assay. Results showed hSET1/SN38 nanoparticles had significantly higher cytotoxicity against HT29 cells compared with nanoparticles containing SN38, free SN38 or naked hSET1. Therefore, present system could be considered an effective combination therapy of highly hydrophobic SN38 and hSET1.

Abstract
A reversible-PEGylated polylysine is designed and developed for efficient delivery of siRNA. In this unique structure, the ε-amino groups of disulfide linked poly(ethylene glycol) (PEG) and polylysine (mPEG-SS-PLL) are partially replaced by histidine groups, in order to develop the histidylated reversible-PEGylated polylysine (mPEG-SS-PLH), for enhanced endosome escape ability. The transfection efficacy of mPEG-SS-PLH is found to closely correlate with histidine substitution. Its maximum transfection efficiencies are determined, respectively, to be 75%, 42%, and 24%, against 293T, MCF-7, and PC-3 cells. These data indicate that the transfection efficiencies can equal or even outweigh PEI-25k in the corresponding cells (80%, 38.5%, and 20%). The in vivo circulation and biodistribution of the polyplexes are monitored by fluorescent imaging. The in vivo gene transfection is carried out by intravenous injection of pEGFP to BALB/c mice using the xenograft models. The in vivo experimental results show effective inhibition of tumor growth by mPEG-SS-PLH/siRNA-VEGF, indicating its high potential for clinical applications.

Abstract
Bioreducible polymers have appeared as ideal gene delivery vectors due to the high stability in extracellular fluids and rapid DNA unpacking in an intracellular reducing environment, as well as decreased cytotoxicity. Disulfide bonds have long been regarded as the only golden standard for this design. Recently, diselenide bonds have emerged as a new reduction-sensitive linkage. However, its reduction sensitivity has not been systematically reported. The primary aim of this study is to compare its reduction sensitivity with the golden standard disulfide bonds. Bioreduction-triggered polymer degradation revealed that diselenide bonds are more stable than disulfide bonds with a lower redox potential (i.e. 10 μM GSH). The changes in DNA binding ability, particle size, zeta potential, and morphology all demonstrated that diselenide bonds have similar reduction sensitivity as disulfide bonds, but it could be only cleaved at a tumor-relevant glutathione concentration (i.e. 10 mM GSH). Förster resonance energy transfer (FRET) spectra suggested that diselenide bond conjugated OEI800 (OEI-SeSex) complexes could not only maintain high stability under 10 μM GSH conditions, but could also timely release DNA under 10 mM GSH conditions. Cell viability assay results showed that OEI-SeSex has a similar cell viability profile as disulfide bond conjugated OEI800 (OEI-SSx), which is much less toxic than PEI25k. Biological efficacy assessment indicated comparable or even outweigh transfection efficiency of OEI-SeSex with OEI-SSx and PEI25k. These results suggested that the unique properties of diselenide bonds have enabled a versatile design of multifunctional bioreducible polymers for in vivo gene delivery.

Abstract
Polylysine with cleavable PEGylation and hydrophobic histidylation (mPEG-SS-Lysn-r-Hism) was designed and developed for efficient siRNA delivery and tumor therapy. mPEG-SS-Lysn-r-Hism was used to carry and deliver small interfering RNA (siRNA) for silencing endogenous vascular endothelial growth factor (VEGF) expression and inhibiting tumor growth in HepG2 tumor-bearing mice. In this gene vector, histidine(Bzl) was selected for hydrophobic histidylation for the proton sponge ability of the imidazole ring and hydrophobic benzyl group. Cleavable PEGylation was introduced for in vivo circulation as well as selective PEG detachment in response to intracellular reduction condition in order to release the genetic payload. PEG detachment induced gene release was supported by agarose gel electrophoresis retardation assay, undertaken in the intracellular relevant reduction condition. In vitro transfection evaluation of histidylated copolymers, using pEGFP as genetic model, indicated significantly higher GFP expression than unmodified counterparts, comparable to the gold standard PEI. The efficacy of hydrophobic histidylation was found to be pronounced in mesenchymal stem cells (MSCs). In vivo application of the VEGF-siRNA package by tailored mPEG-SS-Lysn-r-Hism showed distinct tumor suppression in terms of macroscopic tumor volume and molecular analysis.

Abstract
In the treatment of cancer, multidrug resistance (MDR) has been the major obstacle to the success of chemotherapy. The underlying mechanism relies on the overexpression of drug-efflux transporters that prevent the intracellular transport of the drug. In this study, reduction-cleavable vesicles were designed and developed with efficient glutathione-mediated drug-release behavior for reversing drug resistance. Polymeric vesicles were self-assembled from triblock copolymers with disulfide-bond-linked poly(ethylene glycol) (PEG) and poly(ε-benzyloxycarbonyl-L-lysine) (PzLL). Observations from transmission electron microscopy (TEM) and confocal laser scanning microscopy (CLSM) outline an obvious hollow structure surrounded by a thin outer layer, indicating the successful formation of the vesicles. Using fluorescently detectable doxorubicin hydrochloride (DOX·HCl) as the model drug, a significant acceleration of drug release regulated by glutathione (GSH) was found (>3-fold difference). Upon incubation of the DOX·HCl-loaded polymeric vesicles with the HeLa cervical cancer cell line exposed to glutathione, an enhanced nuclear accumulation of DOX·HCl was observed, elicited by the preferred disassembly of the vesicle structure under reducing conditions. Importantly, by using the gemcitabine hydrochloride (GC·HCl)-resistant breast cancer cell line MDA-MB-231, it was found that cell viability was significantly reduced after treatment with GC·HCl-loaded polymeric vesicles, indicating that these vesicles can help to reverse the drug resistance.

Abstract
Targeting drug formulations to specific tissues and releasing the bioactive content in response to a certain stimuli remains a significant challenge in the field of biomedical science. We have developed a nanovehicle that can be used to deliver "drugs" to "specific" tissues. For this, we have simultaneously modified the surface of the nanovehicle with "drugs" and "tissue-specific ligands". The "tissue-specific ligands" will target the nanovehicle to the correct tissue and release the "drug" of interest in response to specific stimuli. We have synthesised a "lactose surface-modified gold nanovehicle" to target liver cells and release the model fluorescent drug (coumarin derivative) in response to the differential glutathione concentration (between blood plasma and liver cells). Lactose is used as the liver-specific targeting ligand given the abundance of L-galactose receptors in hepatic cells. The coumarin derivative is used as a fluorescent tag as well as a linker for the attachment of various biologically relevant molecules. The model delivery system is compatible with a host of different ligands and hence could be used to target other tissues as well in future. The synthesised nanovehicle was found to be non-toxic to cultured human cell lines even at elevated non-physiological concentrations as high as 100 μg/mL. We discover that the synthesised gold-based nanovehicle shows considerable stability at low extracellular glutathione concentrations; however coumarin is selectively released at high hepatic glutathione concentration.

Abstract
Nanoparticles are attractive drug carriers that can combine drug molecules and targeting moieties in order to improve treatment efficacy and reduce unwanted side effects. In addition, activatable nanoparticles may enable drug release in the target sites at accurate timings or conditions, in which drug discharge can be controlled by specific stimuli. Especially, gold nanoparticles provide a great opportunity as drug carriers because of the following advantageous features: i) simple formulation with various sizes and shapes and non-toxicity; ii) easy incorporation of targeting molecules, drugs or other therapeutic molecules on them; iii) triggered drug release by means of external or internal stimuli. In this chapter, we describe relevant examples of the preparation techniques and the performance of various types of gold nanoparticles for drug delivery as well as theranostics.

Abstract
Polymeric nanoparticles are promising candidates as drug and gene carriers. Among polymeric nanoparticles, those that are responsive to internal or external stimuli are of greater interest because they allow more efficient delivery of therapeutics to pathological regions. Stimulus-sensitive polymeric nanoparticles have been fabricated based on numerous nanostructures, including micelles, vesicles, crosslinked nanoparticles, and hybrid nanoparticles. The changes in chemical or physical properties of polymeric nanoparticles that occur in response to single, dual, or multiple stimuli endow these nanoparticles with the ability to retain cargoes during circulation, target the pathological region, and release their cargoes after cell internalization. This Review focuses on the most recent developments in the preparation of stimulus-sensitive polymeric nanoparticles and their applications in drug and gene delivery.

Abstract
A dual stimulus-responsive mPEG-SS-PLL(15)-glutaraldehyde star (mPEG-SS-PLL(15)-star) catiomer is developed and biologically evaluated. The catiomer system combines redox-sensitive removal of an external PEG shell with acid-induced escape from the endosomal compartment. The design rationale for PEG shell removal is to augment intracellular uptake of mPEG-SS-PLL(15)-star/DNA complexes in the presence of tumor-relevant glutathione (GSH) concentration, while the acid-induced dissociation is to accelerate the release of genetic payload following successful internalization into targeted cells. Size alterations of complexes in the presence of 10 mM GSH suggest stimulus-induced shedding of external PEG layers under redox conditions that intracellularly present in the tumor microenvironment. Dynamic laser light scattering experiments under endosomal pH conditions show rapid destabilization of mPEG-SS-PLL(15)-star/DNA complexes that is followed by facilitating efficient release of encapsulated DNA, as demonstrated by agarose gel electrophoresis. Biological efficacy assessment using pEGFP-C1 plasmid DNA encoding green fluorescence protein and pGL-3 plasmid DNA encoding luciferase as reporter genes indicate comparable transfection efficiency of 293T cells of the catiomer with a conventional polyethyleneimine (bPEI-25k)-based gene delivery system. These experimental results show that mPEG-SS-PLL(15)-star represents a promising design for future nonviral gene delivery applications with high DNA binding ability, low cytotoxicity, and high transfection efficiency.
