Abstract
The effective management of biofilm-associated infections remains a pressing concern in clinical practice, necessitating the development of efficient eradication strategies. This study introduces biotin-modified mesoporous silica nanoparticles (MSN-Biotin) designed to facilitate the delivery of phytochemical agents, including gallic acid and quercetin, for biofilm disruption. We elucidate the synthesis, characterization, and biofilm penetration ability of MSN-Biotin towards gram-negative E. coli biofilm and gram-positive S. mutans biofilms, emphasizing their potential in anti-biofilm drug delivery. Importantly, in vitro experiments demonstrate that MSN-Biotin loaded with phytochemicals achieved significantly better penetration into E. coli and S. mutans biofilms than traditional mesoporous silica nanoparticles and better biofilm eradication ability than free phytochemical molecules. These findings underscore the promise of MSN-Biotin as a potential efficient platform for delivering antimicrobial agents. This study introduces a novel surface modification approach for the development of antibiofilm nanoparticle systems and establishes their significant potential in biofilm infection management.
