Agri-biomass such as rice straw, wheat straw contains 15-20% lignin. Lignin is a naturally abundant polymer rich in polyphenols which possesses immense antioxidant, antimicrobial, adsorbent and UV-blocking properties. Lignin can be used for the preparation of antimicrobial spray, UV-protectant coating, therapeutic nanoparticles and hydrogels for controlled drug release. In this line our research group has been working on developing such lignin derived materials. These materials are industrially relevant and can be used on glass window (as UV protectant coating), on common surfaces (as antimicrobial spray), in drug delivery (as hydrogel) and in wastewater cleanup (as adsorbent). These products are green, low cost and scalable for industrial production and commercialization.
