Antimicrobial resistance (AMR) presents an escalating global challenge as conventional antibiotic treatments become less effective. In response, photodynamic therapy (PDT) and photothermal (PTT) have emerged promising alternatives. While rooted in ancient practices, these methods evolved with modern innovations, particularly through the integration of lasers, refining their efficacy. PDT harnesses photosensitizers to generate reactive oxygen species (ROS), which are detrimental microbial cells, whereas PTT relies on heat induce cellular damage. The key effectiveness lies utilization photosensitizers, especially when integrated into nano- or micron-scale supports, amplify ROS production enhance antimicrobial activity. Over last decade, carbon dots (CDs) a highly nanomaterial, attracting increasing attention owing distinctive properties versatile applications, including PTT.
