Nov 27, 2025 A thermoplastic form of chitosan retains biological activity, enabling molded biodegradable plastics that store enzymes or living microbes and break down pollutants while maintaining strength and stability. (Nanowerk Spotlight) Materials that maintain biological activity are usually soft, wet, and fragile. They exist as hydrogels, thin membranes, or...
Metal-organic framework coatings puncture bacteria to stop biofilms without antibiotics
Nov 27, 2025 Nanostructured metal-organic framework coatings mechanically puncture bacteria, stopping biofilms on surfaces without antibiotics or toxic metals and reducing resistance risks. (Nanowerk News) Bacteria that multiply on surfaces are a major headache in healthcare when they gain a foothold on, for example, implants or in catheters. Researchers at...
