Abstract
Background: Osteoarthritis causes tremendous damage to the joints, reducing the quality of life and imposing significant financial burden. An implantable drug-delivery system can improve the symptomatic manifestations with low doses and frequencies. However, the free drug has short retention in the joint cavity. Materials & methods: This study used electrostatic spinning technology to create an implantable drug-delivery system loaded with celecoxib (celecoxib nanofibers [Cel-NFs]) to improve retention and bioavailability. Results: Cel-NFs exhibited good formability, hydrophilicity and tensile properties. Cel-NFs were able to continuously release drugs for 2 weeks and increase the uptake capacity of Raw 264.7 cells, ultimately ameliorating symptoms in osteoarthritis rats. Conclusion: These results suggest that Cel-NFs can effectively ameliorate cartilage damage, reduce joint pain and alleviate osteoarthritis progression.

Abstract
The aim of this study was to design a chitosan-coated hollow tin dioxide nanosphere (CS-HSn) for loading febuxostat (FEB) using an adsorption method to obtain a sustained-release system (CS-HSn-FEB) to improve the oral bioavailability of FEB. The morphological characteristics of hollow tin dioxide nanospheres (HSn) and CS-HSn were analyzed by transmission electron microscopy (TEM) and dynamic light scattering (DLS). The hemolysis test and CCK-8 test were used to assess the biosafety of HSn and CS-HSn. Powder X-ray diffraction (PXRD) and differential scanning thermal analysis (DSC) were performed on CS-HSn-FEB to analyze the drug presence status. The dissolution behavior and changes in plasma drug concentration of CS-HSn-FEB were evaluated in vitro and in vivo. Sections of intestinal tissues from SD rats were obtained to observe whether chitosan could increase the distribution of nanoparticles in the intestinal tissues. The results showed that FEB was present in CS-HSn in an amorphous state. Moreover, CS-HSn, with good biosafety, significantly improved the water solubility and oral absorption of FEB, indicating that CS-HSn has great potential to improve the intestinal absorption and oral bioavailability of insoluble drugs.

Abstract
This study presents a method for a one-step co-encapsulation of PLGA nanoparticles in hydrophilic nanofibers. The aim is to effectively deliver the drug to the lesion site and achieve a longer release time. The celecoxib nanofiber membrane (Cel-NPs-NFs) was prepared by emulsion solvent evaporation and electrospinning with celecoxib as a model drug. By this method, nanodroplets of celecoxib PLGA are entrapped within polymer nanofibers during an electrospinning process. Moreover, Cel-NPs-NFs exhibited good mechanical strength and hydrophilicity, with a cumulative release of 67.74% for seven days, and the cell uptake at 0.5 h was 2.7 times higher than that of pure nanoparticles. Furthermore, pathological sections of the joint exhibited an apparent therapeutic effect on rat OA, and the drug was delivered effectively. According to the results, this solid matrix containing nanodroplets or nanoparticles could use hydrophilic materials as carriers to prolong drug release time.

Abstract
Riboflavin (RF) is one kind of vitamin B, which has low bioavailability due to the low water solubility and the high photosensitivity during food processing and storage. The anti-solvent precipitation method was applied to fabricate a zein-sodium alginate (SA) binary complexes delivery system with the loading of RF, which was aimed to enhance the delivery efficiency, stability, and controlled release of RF in the gastrointestinal (GI) tract. The formation mechanism, physicochemical properties as well as the digestion behaviors were investigated. The incorporation of SA significantly increased the diameter and decreased the surface positive charge of the nanoparticles. The surface morphology of the nanoparticles was characterized using the scanning electron microscope. The FTIR analysis revealed that the electrostatic attraction was the dominant binding force in the formation of the zein-SA binary complexes nanoparticles. In addition, the study on the in vitro release process showed that the zein-SA nanoparticles could delay the release of the RF under the simulated GI tract conditions, which improved their oral bioavailability. In summary, the zein-SA nanoparticle is an effective vehicle for the oral delivery of RF as well as other vitamins and bioactives in the applications of food and nutrition.

Abstract
With the rapid progress of nanotechnology, various nanoparticles (NPs) have been applicated in our daily life. In the field of nanotechnology, metal-based NPs are an important component of engineered NPs, including metal and metal oxide NPs, with a variety of biomedical applications. However, the unique physicochemical properties of metal-based NPs confer not only promising biological effects but also pose unexpected toxic threats to human body at the same time. For safer application of metal-based NPs in humans, we should have a comprehensive understanding of NP toxicity. In this review, we summarize our current knowledge about metal-based NPs, including the physicochemical properties affecting their toxicity, mechanisms of their toxicity, their toxicological assessment, the potential strategies to mitigate their toxicity and current status of regulatory movement on their toxicity. Hopefully, in the near future, through the convergence of related disciplines, the development of nanotoxicity research will be significantly promoted, thereby making the application of metal-based NPs in humans much safer.

Abstract
The review provides insights into current advancements in electrospinning-assisted manufacturing for optimally designing biomedical devices for their prospective applications in tissue engineering, wound healing, drug delivery, sensing, and enzyme immobilization, and others. Further, the evolution of electrospinning-based hybrid biomedical devices using a combined approach of 3 D printing and/or film casting/molding, to design dimensionally stable membranes/micro-nanofibrous assemblies/patches/porous surfaces, etc. is reported. The influence of various electrospinning parameters, polymeric material, testing environment, and other allied factors on the morphological and physico-mechanical properties of electrospun (nano-/micro-fibrous) mats (EMs) and fibrous assemblies have been compiled and critically discussed. The spectrum of operational research and statistical approaches that are now being adopted for efficient optimization of electrospinning process parameters so as to obtain the desired response (physical and structural attributes) has prospectively been looked into. Further, the present review summarizes some current limitations and future perspectives for modeling architecturally novel hybrid 3 D/selectively textured structural assemblies, such as biocompatible, non-toxic, and bioresorbable mats/scaffolds/membranes/patches with apt mechanical stability, as biological substrates for various regenerative and non-regenerative therapeutic devices.

Abstract
On-demand drug delivery systems using nanofibers have attracted significant attention owing to their controllable properties for drug release through external stimuli. Near-infrared (NIR)-responsive nanofibers provide a platform where the drug release profile can be achieved by the on-demand supply of drugs at a desired dose for cancer therapy. Nanomaterials such as gold nanorods (GNRs) exhibit absorbance in the NIR range, and in response to NIR irradiation, they generate heat as a result of a plasmon resonance effect. In this study, we designed poly (N-isopropylacrylamide) (PNIPAM) composite nanofibers containing GNRs. PNIPAM is a heat-reactive polymer that provides a swelling and deswelling property to the nanofibers. Electrospun nanofibers have a large surface-area-to-volume ratio, which is used to effectively deliver large quantities of drugs. In this platform, both hydrophilic and hydrophobic drugs can be introduced and manipulated. On-demand drug delivery systems were obtained through stimuli-responsive nanofibers containing GNRs and PNIPAM. Upon NIR irradiation, the heat generated by the GNRs ensures shrinking of the nanofibers owing to the thermal response of PNIPAM, thereby resulting in a controlled drug release. The versatility of the light-responsive nanofibers as a drug delivery platform was confirmed in cell studies, indicating the advantages of the swelling and deswelling property of the nanofibers and on-off drug release behavior with good biocompatibility. In addition, the system has potential for the combination of chemotherapy with multiple drugs to enhance the effectiveness of complex cancer treatments.

Abstract
Hydrophilic polyvinyl alcohol (PVA) based electrospun nanofibrous mats (ENMs) are recently being used for the designing and fabrication of active wound dressing materials. Thus, in this study an inclusion complex (IC) of curcumin (CUR) and β-cyclodextrin (β-CD) was optimally incorporated in electrospun PVA nanofibers, to obtain uniform bead-free nanofibers with minimum average diameter and variation using Taguchi's design of experiments (DOE). The optimum level parameters were ascertained using Taguchi's methodology, to obtain IC loaded PVA based bead-free ENMs, by varying IC (∼20, ∼40, and ∼60 wt.%) loading, applied voltage, solution concentration, and N, N-dimethylformamide (DMF) content in the electrospinning solution mixture. Validation experiments revealed a good agreement between the predicted and experimental values of fiber diameter, diameter-variation, and bead-numbers. Analysis of variance (ANOVA) showed a major influence of IC loading on the average fiber diameter and the number of bead defects, for IC-loaded PVA based ENMs. However, the DMF content of the solvent mixture significantly influenced the diameter variations of ENMs. The surface morphologies of ENMs were analyzed using Scanning Electron Microscopy (SEM) whereas the microstructural aspects were studied by Wide-Angle X-ray Diffraction (WAXD) and Fourier transform infrared (FT-IR) spectroscopy. The thermal properties were characterized by differential scanning calorimetry (DSC) and thermogravimetric analysis (TGA) whereas the mechanical properties were measured by using uniaxial tensile testing and dynamic mechanical analysis (DMA). The variation in properties of IC loaded PVA based ENMs were correlated with neat PVA based ENMs fabricated using a similar set of optimized electrospinning process parameters. The study conceptually demonstrated the optimal designing of structurally-engineered hydrophilic IC loaded PVA based ENMs by using the Taguchi approach based on orthogonal DOE as potential drug release substrates.

Abstract
We have designed a new magnetic targeting drug carrier Fe3O4-PVA with a core of triiron tetroxide (Fe3O4) and a shell made of polyvinyl alcohol (PVA) to improve the hydrophilicity of Fe3O4. With adriamycin hydrochloride as a model drug, this study goes on to measure the drug carrier performance of Fe3O4-PVA. In addition, the thermal stability and enthalpy of thermal decomposition of Fe3O4-PVA were measured using a differential scanning calorimeter with a non-isothermal decomposition method. The kinetics of thermal decomposition of Fe3O4-PVA were also investigated. Over the course of this study, it was determined that the resulting drug carrier Fe3O4-PVA exhibited high drug loading levels and excellent release levels.
