Abstract
Bacterial and biofilm infections remain a leading cause of global mortality, prompting a shift beyond conventional antibiotic drug development due to the rapid emergence of antimicrobial resistance. This mini-review delves into giving a brief understanding of the realm of metal-containing nanomaterials, emphasizing their potential in antimicrobial phototherapy free from bacterial resistance. The focus extends to transition metalincorporated materials as a tool to induce photoredox properties akin to photoredox catalysis. Despite highlighting the promise of such materials, the review also addresses concerns regarding biosafety for their in vivo applications. Nonetheless, the utilization of multifaceted photoredox strategies leveraging diverse metal oxidation states, alongside the advantageous light-driven physicochemical attributes of nanosystems, shows promise for combatting challenging pathogenic infections using inorganic materials.
