Abstract
BACKGROUND Global pediatric healthcare reveals significant morbidity and mortality rates linked to respiratory, cardiac, and gastrointestinal disorders in children and newborns, mostly due to the complexity of therapeutic management in pediatrics and neonatology, owing to the lack of suitable dosage forms for these patients, often rendering them "therapeutic orphans". The development and application of pediatric drug formulations encounter numerous challenges, including physiological heterogeneity within age groups, limited profitability for the pharmaceutical industry, and ethical and clinical constraints. Many drugs are used unlicensed or off-label, posing a high risk of toxicity and reduced efficacy. Despite these circumstances, some regulatory changes are being performed, thus thrusting research innovation in this field. DATA SOURCES Up-to-date peer-reviewed journal articles, books, government and institutional reports, data repositories and databases were used as main data sources. RESULTS Among the main strategies proposed to address the current pediatric care situation, nanotechnology is specially promising for pediatric respiratory diseases since they offer a non-invasive, versatile, tunable, site-specific drug release. Tissue engineering is in the spotlight as strategy to address pediatric cardiac diseases, together with theragnostic systems. The integration of nanotechnology and theragnostic stands poised to refine and propel nanomedicine approaches, ushering in an era of innovative and personalized drug delivery for pediatric patients. Finally, the intersection of drug repurposing and artificial intelligence tools in pediatric healthcare holds great potential. This promises not only to enhance efficiency in drug development in general, but also in the pediatric field, hopefully boosting clinical trials for this population. CONCLUSIONS Despite the long road ahead, the deepening of nanotechnology, the evolution of tissue engineering, and the combination of traditional techniques with artificial intelligence are the most recently reported strategies in the specific field of pediatric therapeutics.

Abstract
This study aims to encapsulate gemcitabine (GEM) using a phospholipid complex (PLC) in lipid nanoparticles (NPs) to achieve several desirable outcomes, including high drug loading, uniform particle size, improved therapeutic efficacy, and reduced toxicities. The successful preparation of GEM-loaded lipid NPs (GEM-NPs) was accomplished using the emulsification-solidification method, following optimization through Box-Behnken design. The size of the GEM-NP was 138.5 ± 6.7 nm, with a low polydispersity index of 0.282 ± 0.078, as measured by a zetasizer and confirmed by transmission electron and atomic force microscopy. GEM-NPs demonstrated sustained release behavior, surpassing the performance of the free GEM and phospholipid complex. Moreover, GEM-NPs exhibited enhanced cytotoxicity, apoptosis, and cell uptake in Panc-2 and Mia PaCa cells compared to the free GEM. The in vivo pharmacokinetics revealed approximately 4-fold higher bioavailability of GEM-NPs in comparison with free GEM. Additionally, the pharmacodynamic evaluation conducted in a DMBA-induced pancreatic cancer model, involving histological examination, serum IL-6 level estimation, and expression of cleaved caspase-3, showed the potential of GEM-NPs in the management of pancreatic cancer. Consequently, the lipid NP-based approach developed in our investigation demonstrates high stability and uniformity and holds promise for enhancing the therapeutic outcomes of GEM.

Abstract
A variety of colloidal chemical approaches has been developed in the last few decades for the controlled synthesis of nanostructured materials in either water or organic solvents. Besides the precursors, the solvents, reducing agents, and the choice of surfactants are crucial for tuning the composition, morphology and other properties of the resulting nanoparticles. The ligands employed include thiols, amines, carboxylic acids, phosphines and phosphine oxides. Generally, adding a single ligand to the reaction mixture is not always adequate to yield the desired features. In this review, we discuss in detail the role of the oleic acid/oleylamine ligand pair in the chemical synthesis of nanoparticles. The combined use of these ligands belonging to two different categories of molecules aims to control the size and shape of nanoparticles and prevent their aggregation, not only during their synthesis but also after their dispersion in a carrier solvent. We show how the different binding strengths of these two molecules and their distinct binding modes on specific facets affect the reaction kinetics toward the production of nanostructures with tailored characteristics. Additional functions, such as the reducing function, are also noted, especially for oleylamine. Sometimes, the carboxylic acid will react with the alkylamine to form an acid-base complex, which may serve as a binary capping agent and reductant; however, its reducing capacity may range from lower to much lower than that of oleylamine. The types of nanoparticles synthesized in the simultaneous presence of oleic acid and oleylamine and discussed herein include metal oxides, metal chalcogenides, metals, bimetallic structures, perovskites, upconversion particles and rare earth-based materials. Diverse morphologies, ranging from spherical nanoparticles to anisotropic, core-shell and hetero-structured configurations are presented. Finally, the relation between tuning the resulting surface and volume nanoparticle properties and the relevant applications is highlighted.

Abstract
A unique and pleiotropic polymer, d-alpha-tocopheryl polyethylene glycol succinate (Tocophersolan), is a polymeric, synthetic version of vitamin E. Tocophersolan has attracted enormous attention as a versatile excipient in different biomedical applications including drug delivery systems and nutraceuticals. The multiple inherent properties of Tocophersolan allow it to play flexible roles in drug delivery system design, including excipients with outstanding biocompatibility, solubilizer with the ability to promote drug dissolution, drug permeation enhancer, P-glycoprotein inhibitor, and anticancer compound. For these reasons, Tocophersolan has been widely used for improving the bioavailability of numerous pharmaceutical active ingredients. Tocophersolan has been approved by stringent regulatory authorities (such as the US FDA, EMA, and PMDA) as a safe pharmaceutical excipient. In this review, the current advances in nano-based delivery systems consisting of Tocophersolan, with possibilities for futuristic applications in drug delivery, gene therapy, and nanotheranostics, were systematically curated.

Abstract
Modern-day search for the novel agents (their preparation and consequent implementation) to effectively treat the cancer is mainly fuelled by the historical failure of the conventional treatment modalities. Apart from that, the complexities such as higher rate of cell mutations, variable tumor microenvironment, patient-specific disparities, and the evolving nature of cancers have made this search much stronger in the latest times. As a result of this, in about two decades, the theranostic nanoparticles (TNPs) - i.e., nanoparticles that integrate therapeutic and diagnostic characteristics - have been developed. The examples for TNPs include mesoporous silica nanoparticles, luminescence nanoparticles, carbon-based nanomaterials, metal nanoparticles, and magnetic nanoparticles. These TNPs have emerged as single and powerful cancer-treating multifunctional nanoplatforms, as they widely provide the necessary functionalities to overcome the previous/conventional limitations including lack of the site-specific delivery of anti-cancer drugs, and real-time continuous monitoring of the target cancer sites while performing therapeutic actions. This has been mainly possible due to the association of the as-developed TNPs with the already-available unique diagnostic (e.g., luminescence, photoacoustic, and magnetic resonance imaging) and therapeutic (e.g., photothermal, photodynamic, hyperthermia therapy) modalities in the biomedical field. In this review, we have discussed in detail about the recent developments on the aforementioned important TNPs without/with targeting ability (i.e., attaching them with ligands or tumor-specific antibodies) and also the strategies that are implemented to increase their tumor accumulation and to enhance their theranostic efficacies for effective biomedical cancer treatments.

Abstract
Magnetic nanoparticles are intensively studied for magnetic resonance imaging (MRI) as contrast agents but yet there remained some gaps regarding their toxicity potential and clinical implications of their biodistribution in organs. This study presents the effects induced by magnetite nanoparticles encapsulated in polymeric micelles (MNP-DSPE-PEG) on biochemical markers, metabolic functions, and MRI signal in CD1 mice liver. Three groups of animals, one control and the other ones injected with a suspension of five, respectively, 15 mg Fe/kg bw nanoparticles, were monitored up to 14 days. The results indicated the presence of MNP-DSPE-PEG in the liver in the first two days of the experiment. The most significant biochemical changes also occurred in the first 3 days after exposure when the most severe histological changes were observed. The change of the MRI signal intensity on the T2-weighted images and increased transverse relaxation rates R2 in the liver were observed after the first minutes from the nanoparticle administration. The study shows that the alterations of biomarkers level resulting from exposure to MNP-DSPE-PEG are restored in time in mice liver. This was associated with a significant contrast on T2-weighted images and made us conclude that these nanoparticles might be potential candidates for use as a contrast agent in liver medical imaging.

Abstract
Magnetic fluid hyperthermia (MFH) treatment makes use of a suspension of superparamagnetic iron oxide nanoparticles, administered systemically or locally, in combination with an externally applied alternating magnetic field, to ablate target tissue by generating heat through a process called induction. The heat generated above the mammalian euthermic temperature of 37°C induces apoptotic cell death and/or enhances the susceptibility of the target tissue to other therapies such as radiation and chemotherapy. While most hyperthermia techniques currently in development are targeted towards cancer treatment, hyperthermia is also used to treat restenosis, to remove plaques, to ablate nerves and to alleviate pain by increasing regional blood flow. While RF hyperthermia can be directed invasively towards the site of treatment, non-invasive localization of heat through induction is challenging. In this review, we discuss recent progress in the field of RF magnetic fluid hyperthermia and introduce a new diagnostic imaging modality called magnetic particle imaging that allows for a focused theranostic approach encompassing treatment planning, treatment monitoring and spatially localized inductive heating.

Abstract
Aim: Transferrin anchored, poly(ethylene glycol) (PEG) and α-tocopheryl succinate (α-TOS) conjugated generation 4 dendrimer has been prepared in order to develop a tumor targeted delivery system of a hydrophobic chemotherapeutic agent, paclitaxel (PTX). Materials & methods: The dendrimers were characterized physicochemically for size, ζ and encapsulation ability. The cellular uptake, cytotoxicity potential and apoptosis of prepared nanoconstruct were evaluated in human cervical epithelial cells monolayer and 3D spheroids. Results & conclusion: G4-TOS-PEG-Tf demonstrated increased cellular uptake, cytotoxicity and apoptotic potential of PTX compared with free PTX and G4-TOS-PEG-PTX. G4-TOS-PEG-Tf-PTX inhibited growth of human cervical epithelial cells spheroids significantly. The newly developed dendrimers hold promise as an efficient delivery system for PTX or other hydrophobic chemotherapeutic agents for targeted delivery to tumors.

Abstract
Background S-HM-3 is a tumor angiogenesis inhibitor with short half-life (25 min). In this present, TPGS/Solutol polymeric micelles was prepared to load together insoluble paclitaxel (PTX) and soluble S-HM-3, expecting to together deliver them to the tumor site with long-circulating, targeting function and combating multi-drug resistance (MDR). Materials and methods PTX and S-HM-3 loaded TPGS/Solutol micelles (PHTSm) were prepared by the method of thin-film evaporation, and characterized by dynamic light scattering, transmission electron microscope (TEM), atomic force microscopy (AFM) and releasing properties. The anticancer effect of the polymeric micelles system was evaluated and confirmed by experiments of in vitro cell uptake study, in vivo pharmacokinetics, and pharmacodynamics studies. Results Micelles exhibited smooth spherical morphology with 20~30 nm and low critical micelle concentration (CMC) value of 0.000124 mg/mL. Only about 30% of PTX were slowly released from micelles at 48h, which can beneficial to the long circulation in blood. The results of in vitro cell assay proved that S-HM-3 could be easier to get into MDA-MB-231 cell, and its angiogenesis inhibition ability was also enhanced after integrating into micelles. In particular, the results of in vivo studies showed that the half-life of S-HM-3 and PTX was significantly prolonged 25.27 and 5.54 folds, and their AUC0-∞ was enhanced 129.78 and 15.65 times, respectively. Meanwhile 83.05% tumor inhibition rate of PHTSm was achieved compared with 59.99% of PTX. Conclusions TPGS and Solutol micelles hold promising potential to resolve the conundrum of combined therapy of cytotoxic drug and angiogenesis inhibitor with different physicochemical property and anticancer mechanism in clinical use.

Abstract
Magnetic nanoparticles encapsulated in biocompatible and biodegradable polymeric matrices are promising materials for biomedical applications, such as transport of antitumoral drugs and cancer treatment by hyperthermia. In this study, biobased poly(thioether-ester), PTEe, was obtained by thiol-ene polymerization and superparamagnetic nanoparticles, MNPs, were successfully incorporated in PTEe nanoparticles by miniemulsification followed by solvent evaporation. MNPs-PTEe nanoparticles with average diameter around 150 nm presented superparamagnetic behavior as confirmed by magnetization curves analysis. MNPs-PTEe nanoparticles did not present hemolytic damage on human red blood cells when incubated for 24 h. According to the cell viability assays, nanoparticles did not present any cytotoxic effect on murine fibroblast cell (NIH3T3) and human cervical cancer (HeLa). Hyperthermia assays were applied, demonstrating that AC magnetic field application (110 KHz-500 Oe) for 20 min significantly reduced the cells viability. The morphology evaluation of HeLa showed a hypoxia region one hour after hyperthermia application. Therefore, the results indicated that the superparamagnetic poly(thioether-ester) nanoparticles can be an excellent alternative for the targeted delivery of antitumor drugs and cancer treatment for hyperthermia.

Abstract
In this review we provide a broad overview on the use of nanotechnology for the fight against breast cancer (BC). Nowadays, detection, diagnosis, treatment, and prevention may be possible thanks to the application of nanotechnology to clinical practice. Taking into consideration the different forms of BC and the disease status, nanomaterials can be designed to meet the most forefront objectives of modern therapy and diagnosis. We have analyzed in detail three main groups of nanomaterial applications for BC treatment and diagnosis. We have identified several types of drugs successfully conjugated with nanomaterials. We have analyzed the main important imaging techniques and all nanomaterials used to help the non-invasive, early detection of the lesions. Moreover, we have examined theranostic nanomaterials as unique tools, combining imaging, detection, and therapy for BC. This state of the art review provides a useful guide depicting how nanotechnology can be used to overcome the current barriers in BC clinical practice, and how it will shape the future scenario of treatments, prevention, and diagnosis, revolutionizing the current approaches, e.g., reducing the suffering related to chemotherapy.

Abstract
In this work, we report the synthesis of hydrophilic and surface-functionalized superparamagnetic iron oxide nanoparticles (SPIOs) to utilize them as nanomedicines for treating liver cancer via magnetic fluid hyperthermia (MFH)-based thermotherapy. For this purpose, initially, we have synthesized the SPIOs through co-precipitation/thermolysis methods, followed by in situ surface functionalization with short-chained molecules, such as 1,4-diaminobenzene (14DAB), 4-aminobenzoic acid (4ABA) and 3,4-diaminobenzoic acid (34DABA) and their combination with terephthalic acid (TA)/2-aminoterephthalic acid (ATA)/trimesic acid (TMA)/pyromellitic acid (PMA) molecules. The as-prepared SPIOs are investigated for their structure, morphology, water dispersibility, and magnetic properties. The heating efficacies of the SPIOs are studied in calorimetric MFH (C-MFH) with respect to their concentrations, surface coatings, dispersion medium, and applied alternating magnetic fields (AMFs). Although all of the as-prepared SPIOs have exhibited superparamagnetic behavior, only 14DAB-, 4ABA-, 34DABA-, and 4ABA-TA-coated SPIOs have shown higher magnetization values (Ms = 55-71 emu g-1) and good water dispersibility. In C-MFH studies, 34DABA-coated SPIO-based aqueous ferrofluid (AFF) has revealed faster thermal response to the applied AMF and reached therapeutic temperature even at the lowest concentration (0.5 mg mL-1) compared with 14DAB-, 4ABA-, and 4ABA-TA-coated SPIO-based AFFs. Moreover, 34DABA-coated SPIO-based AFF has exhibited high heating efficacies (i.e., specific absorption rate/intrinsic loss power values of 432.1 W gFe-1/5.2 nHm2 kg-1 at 0.5 mg mL-1), which could be mainly due to (i) enhanced π-π conjugation paths of surface-attached 34DABA coating molecules because of intrafunctional group attractions and (ii) improved anisotropy from the formation of clusters/linear chains of the SPIOs in ferrofluid suspensions, owing to interfunctional group attractions/interparticle interactions. Moreover, the 34DABA-coated SPIOs have demonstrated (i) very good cytocompatibility for 24/48 h incubation periods and (ii) higher killing efficiency of 61-88% (via MFH) in HepG2 liver cancer cells as compared to their treatment with only AMF/water-bath-based thermotherapy. In summary, the 34DABA-coated SPIOs are very promising heat-inducing agents for MFH-based thermotherapy and thus could be used as effective nanomedicines for cancer treatments.

Abstract
Image-guided treatment of cancer enables physicians to localize and treat tumors with great precision. Here, we present in vivo results showing that an emerging imaging modality, magnetic particle imaging (MPI), can be combined with magnetic hyperthermia into an image-guided theranostic platform. MPI is a noninvasive 3D tomographic imaging method with high sensitivity and contrast, zero ionizing radiation, and is linearly quantitative at any depth with no view limitations. The same superparamagnetic iron oxide nanoparticle (SPIONs) tracers imaged in MPI can also be excited to generate heat for magnetic hyperthermia. In this study, we demonstrate a theranostic platform, with quantitative MPI image guidance for treatment planning and use of the MPI gradients for spatial localization of magnetic hyperthermia to arbitrarily selected regions. This addresses a key challenge of conventional magnetic hyperthermia-SPIONs delivered systemically accumulate in off-target organs ( e.g., liver and spleen), and difficulty in localizing hyperthermia results in collateral heat damage to these organs. Using a MPI magnetic hyperthermia workflow, we demonstrate image-guided spatial localization of hyperthermia to the tumor while minimizing collateral damage to the nearby liver (1-2 cm distance). Localization of thermal damage and therapy was validated with luciferase activity and histological assessment. Apart from localizing thermal therapy, the technique presented here can also be extended to localize actuation of drug release and other biomechanical-based therapies. With high contrast and high sensitivity imaging combined with precise control and localization of the actuated therapy, MPI is a powerful platform for magnetic-based theranostics.

Abstract
Interest in theranostic agents has continued to grow because of their promise for simultaneous cancer detection and therapy. A platform-based nanosized combination agent suitable for the enhanced diagnosis and treatment of cancer was prepared using polymeric polyethylene glycol-phosphatidylethanolamine-based micelles loaded with both, poorly soluble chemotherapeutic agent paclitaxel and hydrophobic superparamagnetic iron oxide nanoparticles (SPION), a Magnetic Resonance Imaging contrast agent. The co-loaded paclitaxel and SPION did not affect each other's functional properties in vitro. In vivo, the resulting paclitaxel-SPION-co-loaded PEG-PE micelles retained their Magnetic Resonance contrast properties and apoptotic activity in breast and melanoma tumor mouse models. Such theranostic systems are likely to play a significant role in the combined diagnosis and therapy that leads to a more personalized and effective form of treatment.

Abstract
PURPOSE Transferrin receptor (TfR) is up-regulated in various malignant tumors not only to meet the iron requirement, but also to increase the cell survival via participation in various cellular signaling pathways. Here we explored transferrin as ligand for Poly(ethylene Glycol) (PEG)-ylated vitamin-E/lipid (PE) core micelles (VPM). METHODS Transferrin modified polymer was synthesized and drug loaded micelles were evaluated in 2D Hela and HepG2 cancer cells for cellular uptake and cytotoxicity and in 3D Hela spheroids for growth inhibition, uptake and penetration studies. RESULTS Targeted (Tf-VPM) and non-targeted (VPM) micelles showed mean hydrodynamic diameter of 114.2 ± 0.64 nm and 117.4 ± 0.72 nm and zeta potential was -22.8 ± 0.62 and -14.8 ± 1.74 mV, respectively. Cellular uptake study indicated that the Tf-CVPM were taken up by cancer cells (Hela and HepG2) with higher efficiency. Enhanced cytotoxicity was demonstrated for Tf-VPM compared to CVPM. Marked spheroid growth inhibition following treatment with Tf-CVPM was observed compared to the treatment with non-targeted CVPM. CONCLUSIONS The developed transferrin-modified micelles have improved ability to solubilize the loaded drugs and could actively target solid tumors by its interaction with over-expressed transferrin receptors. Therefore, the nano-micelles could be further explored for its potential utilization in cancer therapy.

Abstract
The conventional chemotherapeutics could not be traced in vivo and provide timely feedback on the clinical effectiveness of drugs. Methods: In this study, a tumor-penetrating peptide RGERPPR (RGE) modified, Gd-DTPA conjugated, and doxorubicin (DOX) loaded Fe3O4@SiO2@mSiO2 nanoparticle drug delivery system (Fe3O4@SiO2@mSiO2/DOX-(Gd-DTPA)-PEG-RGE NPs) was prepared for tumor theranostics. Results: The Fe3O4@SiO2@mSiO2/DOX-(Gd-DTPA)-PEG-RGE NPs showed a z-average hydrodynamic diameter of about 90 nm, and a pH-sensitive DOX release profile. The 3 T MRI results confirmed the relaxivity of the NPs (r1 = 6.13 mM-1S-1, r2 = 36.89 mM-1S-1). The in vitro cellular uptake and cytotoxicity assays on U87MG cells confirmed that the conjugation of RGERPPR played a significant role in increasing the cellular uptake and cytotoxicity of the NPs. The near-infrared fluorescence in vivo imaging results showed that the NPs could be significantly accumulated in the U87MG tumor tissue, which should result from the mediation of the tumor-penetrating peptide RGERPPR. The MRI results showed that the NPs offered a T1-T2 dual mode contrast imaging effect which would lead to a more precise diagnosis. Compared with unmodified NPs, the RGE-modified NPs showed significantly enhanced MR imaging signal in tumor tissue and antitumor effect, which should also be attributed to the tumor penetrating ability of RGERPPR peptide. Furthermore, the Hematoxylin and Eosin (H&E) staining and TUNEL assay proved that the NPs produced obvious cell apoptosis in tumor tissue. Conclusions: These results indicated that Fe3O4@SiO2@mSiO2/DOX-(Gd-DTPA)-PEG-RGE NPs are an effective targeted delivery system for tumor theranostics, and should have a potential value in the personalized treatment of tumor.

Abstract
Alkyl groups (CnH2n+1) are prevalent in engineered bionanomaterials used for many intracellular applications, yet how alkyl groups dictate the interactions between nanoparticles and mammalian cells remains incomprehensively investigated. In this work, we report the effect of alkylation on the cellular uptake of densely polyethylene glycol-coated nanoparticles, which are characterized by their limited entry into mammalian cells. Specifically, we prepare densely PEGylated gold nanoparticles that bear alkyl chains of varying carbon chain lengths (n) and loading densities (termed "alkyl-PEG-AuNPs"), followed by investigating their uptake by Kera-308 keratinocytes. Strikingly, provided a modest alkyl mass percentage of 0.2% (2 orders of magnitude lower than that of conventional lipid-based NPs) in their PEG shells, dodecyl-PEG-AuNPs (n = 12) and octadecyl-PEG-AuNPs (n = 18) can enter Kera-308 cells 30-fold more than methoxy-PEG-AuNPs (no alkyl groups) and hexyl-PEG-AuNPs (n = 6) after 24 h of incubation. Such strong dependence on n is valid for all serum concentrations considered (even under serum-free conditions), although enhanced serum levels can trigger the agglomeration of alkyl-PEG-AuNPs (without permanent aggregation of the AuNP cores) and can attenuate their cellular uptake. Additionally, alkyl-PEG-AuNPs can rapidly enter Kera-308 cells via the filipodia-mediated pathway, engaging the tips of membrane protrusions and accumulating within interdigital folds. Most alkyl-PEG-AuNPs adopt the "endo-lysosomal" route of trafficking, but ∼15% of them accumulate in the cytosol. Regardless of intracellular location, alkyl-PEG-AuNPs predominantly appear as individual entities after 24 h of incubation. Our work offers insights into the incorporation of alkyl groups for designing bionanomaterials for cellular uptake and cytosolic accumulation with intracellular stability.

Sci Rep 2017; 7:2964. [PMID: 28592843 PMCID: PMC5462762 DOI: 10.1038/s41598-017-03123-y] [Citation(s) in RCA: 75] [Impact Index Per Article: 10.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/22/2017] [Accepted: 04/24/2017] [Indexed: 11/09/2022] Open
Abstract
A novel polymeric mixed micelle composed of Pluronic F127 and D-α-tocopheryl polyethylene glycol succinate (TPGS) was developed to improve the delivery of fluorescent dyes and protein across the blood brain barrier (BBB). Rhodamine 123 (Rho123) and DiR loaded mixed micelles, composed of Pluronic F127 and TPGS with proportion of 4:1 (FT), were prepared by thin-film hydration, and β-galactosidase (β-Gal) loaded FT mixed micelles were prepared by self-assembly. The brain-targeted capability of FT mixed micelles were evaluated both in vitro and in vivo. The FT mixed micelles showed that a average particle size of 20.03 nm, and a low CMC of 0.0031% in water. The in vitro release of Rho123 from Rho123 loaded FT mixed micelles (FT/Rho123) presented a sustained-release property. FT/Rho123 also showed higher efficiency for the accumulation in brain capillary endothelial cells (BCECs) and brain tissues. β-Gal, a model protein, was also delivered and accumulated efficiently in the brain by spontaneous loading in the FT mixed micelles. Therefore, the results indicated that F127/TPGS mixed micelles may be considered as an effective nanocarrier for the brain-targeted delivery of diagnostic and therapeutic drugs.

Abstract
Nanomedicines have emerged as a promising treatment strategy for cancer. Multiple drug resistance due to overexpression of various drug efflux transporters and upregulation of apoptotic inhibitory pathways in cancer cells are major barriers that limit the success of chemotherapy. Here, we developed a d-α-tocopherol (α-TOS)/lipid-based copolymeric nanomicellar system (VPM) by conjugating phosphatidyl ethanolamine (PE) and α-TOS with poly(ethylene glycol) (PEG) via an amino acid linkage. The synthesized polymers were characterized by Fourier transform IR, gas-phase chromatography, and 1H and 13C NMR spectroscopy. VPM exhibited mean hydrodynamic diameter of 141.0 ± 0.94 nm with low critical micelles concentrations (CMC) of 15 μM compared to plain PEG-PE micelles (PPM) with size of 23.9 ± 0.34 nm and CMC 20 μM. The bigger hydrophobic compartment in VPM resulted in improved loading of a potent chemotherapeutic drug, curcumin (Cur), and increased encapsulation efficiency (EE) (% drug loading 98.3 ± 1.92, and 85.3 ± 3.29; EE 14.8 ± 0.16 and 12.8 ± 0.09 for VPM and PPM, respectively). Curcumin loaded Vitamin E based micelles exhibited higher cytotoxicity compared to Curcumin loaded PEG-PE micelles in tested cancer cell lines. C-VPM demonstrated ∼3.2 and ∼2.7-fold higher ability to reverse multiple drug resistance compared to PPM and verapamil (concentration used 30 μM), respectively. In the in vivo study by using B16F10 implanted C57Bl6/J mice, C-VPM reduced the tumor volume and weight more efficiently than C-PPM by inducing apoptosis as analyzed by TUNEL assay on tumor cryosections. The newly developed polymeric micelles, VPM with improved drug loadability and ability to reverse the drug resistance could successfully be utilized as a nanocarrier system for hydrophobic chemotherapeutic agents for the treatment of drug-resistant solid tumors.

Abstract
A novel oral drug delivery system, TPGS modified docetaxel proniosomes (DTX-TPGS-PNs), was designed to enhance the oral bioavailability and antitumor efficiency of the poorly water-soluble drug docetaxel. DTX-TPGS-PN niosomes were 93 ± 6.5 nm in size, -18.53 ± 1.65 mV in zeta potential and exhibited spherical morphology, with an encapsulation efficiency of 97.31 ± 0.60%. The system showed sustained release in both simulated gastric and intestinal fluid. The results of caco-2 monolayer, everted gut sac model and improved single-pass intestinal perfusion model transport studies showed that DTX-TPGS-PN niosomes could significantly improve the absorption of DTX. The pharmacokinetics study suggested the absolute bioavailability of DTX-TPGS-PN niosomes were 7.3 times that of DTX solution. In addition, a higher antitumor efficacy than DTX solution was demonstrated in MCF-7 and MDA-MB-231 cells in vitro and in MCF-7 tumor-bearing mice model in vivo. Our results demonstrated DTX-TPGS-PN is promising in enhancing the bioavailability and efficiency of poorly water-soluble drug DTX, and the potential of proniosomes as stable precursors for oral drug delivery.

Abstract
Superparamagnetic iron oxide nanoparticles (SPIO NPs) have a wide range of biomedical applications such as in magnetic resonance imaging, targeting, and hyperthermia therapy. Aggregation of SPIO NPs can occur because of the hydrophobic surface and high surface energy of SPIO NPs. Here, we developed a facile method to encapsulate SPIO NPs in amphiphilic biodegradable polymer. Anionic biodegradable polyurethane nanoparticles (PU NPs) with ~35 nm size and different chemistry were prepared by waterborne processes. SPIO NPs were synthesized by chemical co-precipitation. SPIO NPs were then added to the aqueous dispersion of PU NPs, followed by application of high-frequency (~20 kHz) ultrasonic vibration for 3 min. This method rendered SPIO-PU hybrid NPs (size ~110 nm) suspended in water. SPIO-PU hybrid NPs contained ~50-60 wt% SPIO and retained the superparamagnetic property (evaluated by a magnetometer) as well as high contrast in magnetic resonance imaging. SPIO-PU NPs also showed the ability to provide cell hyperthermic treatment. Using the same ultrasonic method, hydrophobic drug (Vitamin K3 [VK3]) or (9-(methylaminomethyl) anthracene [MAMA]) could also be encapsulated in PU NPs. The VK3-PU or MAMA-PU hybrid NPs had ~35 nm size and different release profiles for PUs with different chemistry. The encapsulation efficiency for VK3 and MAMA was high (~95%) without burst release. The encapsulation mechanism may be attributed to the low glass transition temperature (Tg) and good mechanical compliance of PU NPs. The new encapsulation method involving waterborne biodegradable PU NPs is simple, rapid, and effective to produce multimodular NP carriers.

Abstract
Conventional chemotherapy is the most valid method to cope with cancer; however, it has serious drawbacks such as decrease in production of blood cells or inflammation of the lining of the digestive tract. These side effects occur since generally the drugs used in chemotherapy are distributed evenly within the body of the patient and cannot distinguish the cancer cells from the healthy ones. In this study, folic acid (FA)-conjugated, polyethylene-coated magnetic nanoparticles (FA-MNPs), and doxorubicin (Dox)-loaded formulation (Dox-FA-MNPs) were prepared. The cytotoxicity of these nanoparticles on HeLa and Dox-resistant HeLa cells was investigated. Magnetic nanoparticles (MNPs), polyethylene glycol (PEG)-coated MNPs (PEG-MNPs), and FA-MNPs were successfully synthesized and characterized by several methods. Dox loading of FA-MNPs and release profile of Dox from the nanoparticles were studied. Cytotoxic effects of FA-MNPs and Dox-FA-MNPs on HeLa cells were analyzed. MNPs, PEG-MNPs, and FA-MNPs all had small sizes and supermagnetic behavior. High amounts of Dox could be loded onto the nanoparticles (290 μgmL-1). In 24 h, 15.7% of Dox was released from the Dox-FA-MNPs. The release was increased in acidic conditions (pH 4.1). Internalization studies showed that FA-MNPs and Dox-FA-MNPs were taken up efficiently by HeLa cells. The investigation of cytotoxicity of the particles indicated that 38-500 μgmL-1 Dox-FA-MNPs significantly decreased the proliferation of HeLa cells compared to FA-MNPs. Due to their size, magnetic properties, internalization, drug release, and cytotoxicity characteristics, the MNPs prepared in this study may have potential application as a drug delivery system in cancer chemotherapy.

Abstract
To enhance the formononetin (FN) antitumor effect, we developed a passive targeting FN-contained formulation. FN-contained Vitamin E d-α-tocopheryl polyethylene glycol 1000 succinate (vitamin E TPGS or TPGS)/phospholipid micelles were prepared by the solvent injection method. Particle size, polydispersity, zeta potential, encapsulation efficiency, drug release profile, and micelles morphology were evaluated and characterized by various methods including high-performance liquid chromatography, dynamic light scattering, and transmission electron microscopy. Cellular uptake of micelles was evaluated with fluorescence imaging coupled with HPLC method. Cytotoxicity of FN micelles and free FN was compared using MTT method. In vivo imaging was employed to assess the accumulation of DiR micelles and free DiR at tumor site. The antitumor effect of FN micelles was examined in tumor-bearing mice. The results showed that prepared FN micelles had an average particle diameter of 111.91 ± 5.82 nm with good stability. FN micelles enhanced the cellular uptake and improved cell cytotoxicity than free FN. Furthermore, DiR micelles quickly accumulated at the tumor site than free DiR. FN micelles significantly improved tumor inhibition rate compared to that observed with free FN in tumor-bearing mice with great biosafety. Thus, FN micelles demonstrated a clear treatment advantage and provided an ideal drug administration system to improve the antitumor effect of FN.

Abstract
Targeted drug delivery is one of the key challenges in cancer nanomedicine. Stoichiometric and spatial control over the antibodies placement on the nanomedicine vehicle holds a pivotal role to overcome this key challenge. Here, a DNA tetrahedral is designed with available conjugation sites on its vertices, allowing to bind one, two, or three cetuximab antibodies per DNA nanostructure. This stoichiometrically definable cetuximab conjugated DNA nanostructure shows enhanced targeting on the breast cancer cells, which results with higher overall killing efficacy of the cancer cells.

Abstract
The effective treatment of brain cancer is hindered by the poor transport across the blood-brain barrier (BBB) and the low penetration across the blood-tumor barrier (BTB). The objective of this work was to formulate transferrin-conjugated docetaxel (DTX)-loaded d-alpha-tocopheryl polyethylene glycol 1000 succinate (vitamin E TPGS or TPGS) micelles for targeted brain cancer therapy. The micelles with and without transferrin conjugation were prepared by the solvent casting method and characterized for their particle size, polydispersity, drug encapsulation efficiency, drug loading, in vitro release study and brain distribution study. Particle sizes of prepared micelles were determined at 25 °C by dynamic light scattering technique. The external surface morphology was determined by transmission electron microscopy analysis and atomic force microscopy. The encapsulation efficiency was determined by spectrophotometery. In vitro release studies of micelles and control formulations were carried out by dialysis bag diffusion method. The particle sizes of the non-targeted and targeted micelles were <20 nm. About 85% of drug encapsulation efficiency was achieved with micelles. The drug release from transferrin-conjugated micelles was sustained for >24 h with 50% of drug release. The in vivo results indicated that transferrin-targeted TPGS micelles could be a promising carrier for brain targeting due to nano-sized drug delivery, solubility enhancement and permeability which provided an improved and prolonged brain targeting of DTX in comparison to the non-targeted micelles and marketed formulation.

Abstract
An α-tocopheryl succinate (α-TOS) containing diblock copolymer micellar system was used to deliver doxorubicin (Dox), an anticancer drug, for HCT116 colon cancer therapy. The α-TOS containing diblock copolymers were synthesized by conjugation of α-TOS molecules and a mPEG-b-PHEMA hydrophilic diblock copolymer by ester bonds. The Dox-loaded polymeric micelles were then obtained by solvent exchange process. In acidic surroundings such as endosomes or secondary lysosomes, the structures of the Dox-loaded polymeric micelles deformed and released the drug loads. Additionally, Dox-loaded polymeric micelles enhanced the cytotoxicity of Dox and α-TOS to cancer cells in vitro. Dox-loaded polymeric micelles also showed an exceptional tumor inhibiting effect in vivo. This study indicates that the α-TOS containing polymeric micelle system can be used as a drug carrier for cancer therapy.

Abstract
Superparamagnetic iron oxide (SPIO) nanoparticles have the potential for use as a multimodal cancer therapy agent due to their ability to carry anticancer drugs and generate localized heat when exposed to an alternating magnetic field, resulting in combined chemotherapy and hyperthermia. To explore this potential, we synthesized SPIOs with a phospholipid-polyethylene glycol (PEG) coating, and loaded Doxorubicin (DOX) with a 30.8% w/w loading capacity when the PEG length is optimized. We found that DOX-loaded SPIOs exhibited a sustained DOX release over 72 hours where the release kinetics could be altered by the PEG length. In contrast, the heating efficiency of the SPIOs showed minimal change with the PEG length. With a core size of 14 nm, the SPIOs could generate sufficient heat to raise the local temperature to 43 °C, sufficient to trigger apoptosis in cancer cells. Further, we found that DOX-loaded SPIOs resulted in cell death comparable to free DOX, and that the combined effect of DOX and SPIO-induced hyperthermia enhanced cancer cell death in vitro. This study demonstrates the potential of using phospholipid-PEG coated SPIOs for chemotherapy-hyperthermia combinatorial cancer treatment with increased efficacy.

Abstract
Application of superparamagnetic iron oxide nanoparticles (NPs) as a negative contrast agent in magnetic resonance imaging (MRI) has been of widespread interest. These particles can enhance contrast of images by altering the relaxation times of the water protons. In this study, dextrin-coated zinc substituted cobalt-ferrite (Zn0.5Co0.5Fe2O4) NPs were synthesized by a co-precipitation method, and the morphology, size, structure and magnetic properties of the NPs were investigated. These NPs had superparamagnetic behavior with an average size of 3.9 (±0.9, n=200)nm measured by transmission electron microscopy. Measurements on the relaxivities (r2 and r2(*)) of the NPs were performed in vitro by agarose phantom. In addition, after subcutaneous injection of the NPs into C540 cell line in C-57 inbred mice, the relaxivities were measured in vivo by a 1.5T MRI system. These NPs could effectively increase the image contrast in both T2-and T2(*)-weighted samples.

Abstract
The various classes of gene delivery vectors possess distinct advantages and disadvantages, each of which impacts on cargo loading, delivery and, ultimately, its function. With this in mind, herein we report on a small layered double hydroxide (sLDH)–liposome composite system, drawing upon the salient features of LDH and liposome classes of vectors, while avoiding their inherent shortfalls when used independently. sLDH–liposome composites were prepared by the hydration of freeze-dried matrix method. These composite systems, with a Z-average size of ≈200 nm, exhibited low cytotoxicity and demonstrated good suspension stability, both in water and cell culture medium after rehydration. Our studies demonstrate that short dsDNAs/ssDNAs were completely bound and protected in the composite system at an sLDH:DNA mass ratio of 20:1, regardless of the approach to DNA loading. This composite system delivered DNA to HCT-116 cells with ≈3-fold greater efficiency, when compared to sLDH alone. Our findings point towards the sLDH-liposome composite system being an effective and biocompatible gene delivery system.

Abstract
miRNA-16 (miR16) plays an important role in modulating the drug resistance of SGC7901 cell lines to adriamycin (ADR). A variety of viral carriers have been designed for miRNA delivery. However, the safety concerns are currently perceived as hampering the clinical application of viral vector-based therapy. Herein a type of magnetic nanoparticles (MNPs) was designed and synthesized using poly(ethylene glycol) (PEG)-coated Fe₃O₄ nanoparticles as a miRNA delivery system for the purpose of reducing drug resistance of gastric cancer cells by enforcing miR16 expression in SGC7901/ADR cells. The MNPs with good biocompatibility were synthesized by thermal decomposition, and then conjugated with miRNA via electrostatic interaction producing miR16/MNPs. After co-culture with miR16/MNPs, ADR-induced apoptosis of SGC7901/ADR was examined by MTT and TUNEL. miR16/MNPs treatment significantly increased cell apoptosis in vitro. SGC7901/ADR(fluc) tumor-bearing nude mice under ADR therapy were treated with miR16/MNPs by tail vein injection for in vivo study. After intraperitoneal injection of ADR, tumor volume measurement and fluorescence imaging were performed to for the death of SGC7901/ADR cells in vivo. Results showed that miR16/MNPs were able to significantly suppress SGC7901/ADR tumor growth, probably through increasing SGC7901/ADR cells' sensitivity to ADR. Our results suggest the efficient delivery of miR16 by MNPs as a novel therapeutic strategy for drug resistant tumor treatment.

Novel nelfinavir mesylate loaded d-α-tocopheryl polyethylene glycol 1000 succinate micelles for enhanced pediatric anti HIV therapy: In vitro characterization and in vivo evaluation. Colloids Surf B Biointerfaces 2014; 123:302-10.

Abstract
Worldwide more than 35 million people are living with Human Immunodeficiency Virus (HIV) where 3.3 million are children. This translates in approximately 700 new daily infections in children only in 2012. Prolonged High Activity Antiretroviral Therapy (HAART) regimes could present low-patient compliance, especially in children, affecting therapeutic success. Nelfinavir mesylate (NFV) is a non-peptidic HIV-1 protease inhibitor (IP) which was the first IP recommended for pediatric use (>2 years-old). It exhibits pH-dependant aqueous solubility which results highly restricted at physiological pH values. The former represents a main clinical limitation due to the reduction on drug absorption along the small intestine after an oral administration, leading to unpredictable drug bioavailability. Moreover a liquid formulation of NFV is not available worldwide, preventing appropriate dose adjustment and more convenient administration. In this framework, the present investigation reports the development of a NFV highly concentrated aqueous formulation for a more appropriate management of pediatric anti-HIV therapy. The aim was to encapsulate NFV within D-α-tocopheryl polyethylene glycol 1000 succinate micelles to improve its aqueous solubility and its oral pharmacokinetic parameters. Results show that NFV aqueous solubility was increased up to 80.3 mg/mL. NFV-loaded micelles exhibited a hydrodynamic diameter of 5.6 nm and a spherical morphology as determined by dynamic light scattering and transmission electronic microscopy, respectively. In vitro NFV release profile demonstrated a cumulative drug release of 56% at 6 h. Finally, in vivo data showed a significant (p<0.01) increase of Area-Under-the-Curve between 0 and 24 h for NFV encapsulated in micelles in comparison with a NFV suspension prepared with glycerin 20% v/v and carboxymethylcellulose sodium 0.5% w/v, representing an increment on drug oral relative bioavailability of 1.71-fold. Thereby, this formulation represents an innovative nanotechnological platform to improve pediatric HIV pharmacotherapy.

Abstract
Polymeric micelles represent an effective delivery system for poorly water-soluble anticancer drugs. With small size (10-100 nm) and hydrophilic shell of PEG, polymeric micelles exhibit prolonged circulation time in the blood and enhanced tumor accumulation. In this review, the importance of rational design was highlighted by summarizing the recent progress on the development of micellar formulations. Emphasis is placed on the new strategies to enhance the drug/carrier interaction for improved drug-loading capacity. In addition, the micelle-forming drug-polymer conjugates are also discussed which have both drug-loading function and antitumor activity.

Abstract
Nanotheranostics is to apply and further develop nanomedicine strategies for advanced theranostics. This review summarizes the various nanocarriers developed so far in the literature for nanotheranostics, which include polymer conjugations, dendrimers, micelles, liposomes, metal and inorganic nanoparticles, carbon nanotubes, and nanoparticles of biodegradable polymers for sustained, controlled and targeted co-delivery of diagnostic and therapeutic agents for better theranostic effects with fewer side effects. The theranostic nanomedicine can achieve systemic circulation, evade host defenses and deliver the drug and diagnostic agents at the targeted site to diagnose and treat the disease at cellular and molecular level. The therapeutic and diagnostic agents are formulated in nanomedicine as a single theranostic platform, which can then be further conjugated to biological ligand for targeting. Nanotheranostics can also promote stimuli-responsive release, synergetic and combinatory therapy, siRNA co-delivery, multimodality therapies, oral delivery, delivery across the blood-brain barrier as well as escape from intracellular autophagy. The fruition of nanotheranostics will be able to provide personalized therapy with bright prognosis, which makes even the fatal diseases curable or at least treatable at the earliest stage.
