Preparation and Biological Activity of Lignin-Silver Hybrid Nanoparticles.

Silver nanoparticles (AgNPs) are excellent antimicrobial agents and promising candidates for preventing or treating bacterial infections caused by antibiotic resistant strains. However, their increasing use in commercial products raises concerns about their environmental impact. In addition, traditional physicochemical approaches often involve harmful agents and excessive energy consumption, resulting in AgNPs with short-term colloidal stability and silver ion leaching.

Bimetallic nanoparticle production using and waste extracts.

The utilization of waste materials for the synthesis of nanoparticles has gained significant attention due to its potential for waste valorization and contribution to circular economy. In this study, bimetallic nanoparticles were produced using extracts derived from and waste, focusing on their green synthesis and antimicrobial activity against Gram-negative bacteria, specifically several strains of . The canes and post-extraction waste from were processed using an ethanol extraction method.
