Three types of chitosan-based films have been prepared and evaluated: a non-modified chitosan film bearing cationizable aliphatic amines and two films made of N-sulfopropyl chitosan derivatives bearing both aliphatic amines and negative sulfonate groups at different ratios. Cell adhesion and proliferation on chitosan films of C2C12 pre-myoblastic cells and B16 cells as tumoral model have been tested. A differential cell behavior has been observed on chitosan films due to their different surface modification. B16 cells have shown lower vinculin expression when cultured on sulfonated chitosan films. This study shows how the interaction among cells and material surface can be modulated by physicochemical characteristics of the biomaterial surface, altering tumoral cell adhesion and proliferation processes.

Chitosan is a modified natural biopolymer obtained through the deacetylation of chitin, which is primarily found in the shells of crustaceans. Chitosan has recently attracted a lot of attention due to its possible use in the chemical, medical and food and industries. Due to its distinct biological activities and functional properties, its applications in the food industry are especially noteworthy.

The multifunctional systems presented here introduce an innovative and deeply thought-out approach to the more effective and safer use of temozolomide (TMZ) in treating glioma. The developed hydrogel-based flakes were designed to address the issues of local GBL therapy, bacterial neuroinfections, and the bleeding control needed during tumor resection. The materials obtained comprise TMZ and vancomycin (VANC) loaded into cyclodextrin/polymeric capsules and embedded into gelatin/hyaluronic acid/chitosan-based hydrogel films cross-linked with genipin.

This study addresses the growing need for sustainable and multifunctional materials by developing novel polycaprolactone (PCL)/chitosan (CS)/zirconium dioxide (ZrO) nanocomposite films. While PCL and CS offer biocompatibility and biodegradability, their combined use presents limitations for advanced applications requiring specific functional features. The incorporation of ZrO nanoparticles aims to overcome these limitations and create materials with enhanced mechanical, electrical, optical, and antibacterial properties.

In this work, cerium oxide nanoparticles prepared through the solvothermal route (sCeO NPs) are integrated into chitosan (CH) matrices to serve as an efficient coating for banana preservation. The morphological, structural, mechanical, and water-barrier properties of nanocomposite films integrated with various sCeO concentrations were investigated to determine the optimal sCeO NPs concentration within the film matrix. Furthermore, the sensory evaluation and physicochemical properties of the coated and uncoated bananas, including visual attributes, peel browning, CO production, firmness, weight loss, ripening rate (based on total soluble solids and titratable acidity), and pH, are considered during storage.

Fresh walnuts are prone to moisture loss and spoilage after harvest, leading to reduced appearance and sensory quality. In this study, a multifunctional chitosan (CS)-based film was fabricated by incorporating a bacterial cellulose/oregano essential oil (BC/OEO) Pickering emulsion, with hydrogen bonding promoting cohesive matrix integration. The film's physicochemical properties, along with its antimicrobial and antioxidant activities, were systematically evaluated.
