Congratulations to Taoran Wang and Wusigale (co-first authors) on having their research paper published in Advanced Composites and Hybrid Materials. The article, entitled "Polydopamine-coated chitosan hydrogel beads for synthesis and immobilization of silver nanoparticles to simultaneously enhance antimicrobial activity and adsorption kinetics", showcases our recent collaborative project on developing the innovative and multi-functional chitosan-based hydrogel beads with immobilized with silver nanoparticles (AgNPs) via polydopamine coating to simultaneously enhance antimicrobial and adsorption activity. The findings from this study demonstrate that AgNPs (2.5 nm) not only significantly improved the adsorption performance of the chitosan hydrogel beads and but also dramatically enhanced their antibacterial activity against both Gram-negative bacteria than Gram-positive bacteria. This work has developed an integrative approach to efficiently control both the microbial and chemical quality of wastewater. Please read the paper here.
Polydopamine coating on chitosan beads enables the immobilization of in situ synthesized silver nanoparticles for superior adsorption and antimicrobial activity.
