Summary: This study addressed the insufficient mechanical strength of natural hydrogel scaffolds in bone tissue engineering by incorporating regenerated cellulose nanofibers into chitosan hydrogel. The resulting rCL/CS composite scaffold showed improved compressive strength, biomineralization, and pre-osteoblast cell viability. The enhanced osteogenic differentiation ability of rCL/CS composite scaffold suggests its promise as a three-dimensional bio-scaffold for bone tissue engineering.

Summary: Chitosan-based nanofibers are promising biomaterials for wound healing and dressing applications due to their biocompatibility, biodegradability, and antibacterial properties. However, their unstable spinnability has limited their further use. In this study, oleamide, a fatty acid amide, was added to chitosan to improve the spinnability of the nanofibers. The addition of oleamide resulted in lower viscosity of the electrospinning solution, leading to enhanced spinnability. The chitosan/oleamide nanofibers exhibited higher hydrophobicity and decreased tensile strength compared to chitosan-only nanofibers. Cell adhesion in vitro was similar or slightly higher on the blended nanofibers, but cell proliferation was decreased, likely due to the increased hydrophobicity. These findings suggest that chitosan/oleamide nanofibers with improved spinnability could be used for wound dressing with antibacterial properties and moderate hydrophobicity.

Summary: In this study, CS/PA6 composite nanofibers were prepared by electrospinning and the addition of GO improved the performance of the composite nanofibers. The results showed that the addition of GO led to the formation of a spider-web-like structure and improved the Young's modulus and thermal degradation resistance of the nanofibers. Furthermore, the prepared composite nanofibers exhibited good adsorption capacity for lead ions.

Summary: This study investigated the impact of the surface charge of concentrated polymer brush (CPB)-grafted cellulose nanofibers (CNFs) on HepG2 cell flocculation. The results showed that the surface charge affected the floc size, with anionic CNF forming larger flocs compared to cationic ones, and lower zeta-potential leading to smaller floc sizes. Appropriate electrostatic interactions are crucial for floc formation and improved cell function in three-dimensional (3D) cell culture systems.
