Development of cell adhesive and inherently antibacterial polyvinyl alcohol/polyethylene oxide nanofiber scaffolds via incorporating chitosan for tissue engineering

Bioprinted biomimetic hydrogel matrices guiding stem cell aggregates for enhanced chondrogenesis and cartilage regeneration

“…20 In addition to low-adhesive polymers, chitosan has been found to improve the calcium binding capacity of the substrate and up-regulate the N-cadherin adhesion molecule, facilitating stem cells into spheroids. 21,22 Moreover, it is remarkable that the cellular spheroids on chitosan-based scaffolds exhibited long-term proliferation and high chondrogenic differentiation efficiency. 23 Various chitosan-based coatings, films, and nanofiber sponges have been prepared for improving the formation of cell spheroids due to the biological signaling function of chitosan.…”

Fabrication and Characterization of Electrospun Chitosan/Polylactic Acid (CH/PLA) Nanofiber Scaffolds for Biomedical Application

“…The presence of nanosized pores within the fibrous mats enhances their permeability, facilitating the exchange of oxygen and nutrients with the surrounding environment. Moreover, the porous structure of the fibrous mat promotes the absorption of wound exudate while reducing the risk of bacterial infections [ 22 ].…”

Engineering the optical, and dielectric properties of (PVA: PVP)/BaSnO3 polymer nanocomposites as promising films for optoelectronics and energy storage applications

“…18,20 Accordingly, the combination of two polymers (PVA/PVP), in one blend perceived special interest in recent years because it yields polymeric membranes with synergetic properties. 21,22 Also, it has been recognized that the final blend member has a grand compatibility that comes from the interaction of the hydrogen bond 23,24 making it a very adequate host for different fillers. 17 More than that, the interaction between the hydroxyl group ( OH) of PVA with the carbonyl group (C O) of PVP provides the final blend with high stability.…”
