Antimicrobial Coating from Agricultural Waste

Recently, a team of scientists from the Department of Biotechnology-Center of Innovative and Applied Bioprocessing (DBT-CIAB), Mohali, has developed a nanocomposite using lignin and nanoparticles of cadmium sulfide called L@CdS QDs (quantum dots).

About Lignin

• Lignin is a complex, woody biopolymer that gives mechanical support to plants and helps transport water and nutrients.
• Post-harvest, lignin is left over as stubble, either burnt or used as cattle feed. Lignin is rich in carbon, polyphenols, and antioxidants, besides having antimicrobial properties.

Key Points

• The Nanocomposite: In their attempt to derive biodegradable nanomaterials for biomedical applications, the team used green methods to synthesize ....
