Summary: Cellulose and its derivatives are commonly used as nanofibrous biomaterials, but research on obtaining 3D cellulose nanofibers is limited. This study presents a simple method for converting electrospun 3D cellulose acetate/lactic acid nanofibers into a 3D cellulose/calcium lactate nanocomposite matrix, resulting in a stronger and more cell-friendly material suitable for bone tissue engineering. The successful conversion was verified through various analytical techniques, and the scaffolds were found to provide a suitable environment for cell growth and infiltration.

Summary: In this study, a two-stage approach for preparing composites with covalently anchored AuNPs was proposed. Firstly, 5 nm AuNPs with high catalytic activity for the reduction of 4-nitrophenol were synthesized and stabilized using fully oxidized and solubilized 2,3-dialdehyde cellulose (DAC). Then, the prepared nanoparticles were tethered to chitosan nanofibers using the carbonyl groups in the nanoparticle shell through an affinity anchoring process. The composite showed improved stability over a wide pH range and demonstrated high catalytic efficacy, fast conversion rates, and direct reusability.

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 has shown to be an effective alternative for coating surfaces due to its broad antibacterial spectrum. The study identified a chitosan sample with the best antibacterial effect, which was successfully grafted onto PTFE surfaces. Comparing two different spacer molecules, poly(ethylene glycol) bis (carboxymethyl) ether and poly(ethylene-alt-maleic anhydride), the latter resulted in a coating with more attached chitosan and significantly better antibacterial action against bacterial strains, while also showing compatibility with human fibroblasts in cytotoxicity tests.
