"Chitosan-based Method Bonds Hydrogels and Polymeric Materials"

Originally Published 1 year ago — by Phys.org

Scientists at the Wyss Institute for Biologically Inspired Engineering at Harvard University and Harvard John A. Paulson School of Engineering and Applied Sciences have developed a simple and versatile method to bond hydrogels and other polymeric materials using a thin film of chitosan, derived from shellfish. This new approach allows for rapid and strong bonding of hydrogels, opening up numerous potential applications in regenerative medicine and surgical care, such as tissue cooling, wound care, and prevention of surgical adhesions. The method could lead to the creation of devices for various medical challenges and offers elegant solutions for urgent unmet problems in regenerative and surgical medicine.

"Breakthrough: Biodegradable Film Extends Food Freshness"

Originally Published 2 years ago — by Phys.org

A research group in Brazil has developed a biodegradable film made from a compound derived from limonene, the main component of citrus fruit peel, and chitosan, a biopolymer derived from crustacean exoskeletons. The film has enhanced bioactive properties, including antioxidant and antimicrobial properties, and performs well in terms of light and water vapor protection. However, it is not yet available for commercial use due to the need for optimization of the production process and scalability of chitosan-based plastic. The researchers are working on improving the yield and testing the film during the manufacturing of commercial packaging.
