Application

• The lignin-based zinc oxide nanoparticles can be used as UV-blocking and antimicrobial ingredients in sunscreen formulations. Additionally, they have potential applications in body creams and other versatile industrial products requiring UV protection and antimicrobial activity.

Description

Scientists at the Center for Innovative and Applied Bioprocessing (CIAB) developed a sustainable antimicrobial sunscreen using lignin derived from agricultural waste, like wheat and rice husks. They synthesized zinc oxide (ZnO) nano-composites from lignin in a green, non-toxic process, making the product eco-friendly. These nano-formulations provide UV protection and antimicrobial properties, showing promise for use in body creams and other industrial applications. This innovative approach converts agricultural waste into valuable, eco-conscious bioproducts.

 

Pathway Description:

The process involves synthesizing zinc oxide (ZnO) nanoparticles using lignin from agricultural waste as a reducing and capping agent. This green, solvent-free method is performed in a water-ethanol solution, avoiding toxic chemicals and high temperatures.
