This research develops biodegradable “living” water filters grown from kombucha cellulose membranes. Unlike conventional plastic filters, these biofilters can self-defend against harmful microbes and self-repair when damaged. The work aims to create affordable, sustainable, and effective water filtration systems that reduce plastic waste while improving access to clean drinking water.

This research develops a new chemical process for modifying cellulose while keeping it in water, overcoming longstanding compatibility problems between cellulose and oil-soluble molecules. The method enables cellulose to incorporate electronic and pharmaceutical components, opening pathways toward sustainable electronics, advanced materials, targeted medicines, and greener technologies based on renewable natural resources.
