The growing demand for sustainable materials in medical technology has led to increased interest in bio-based polymers. A recent publication in RSC Sustainability highlights chitosan as a highly promising material for implantable sensors and bioelectronic systems. Its biocompatibility, functional amino groups, and tunable mechanical and electrical properties make chitosan particularly attractive for next generation biomedical devices.

Chitosan is a versatile biopolymer that is gaining increasing importance in the food and packaging sectors. With its antimicrobial properties, biodegradability, and film-forming capacity, it offers sustainable solutions for shelf-life extension and plastic-free packaging. However, its effectiveness is not determined by degree of deacetylation (DDA) and molecular weight (MW) alone – rather, it results from a combination of chemical and physical characteristics that determine its suitability for different applications.
