0D Fluorescent Nanomaterials: Preparation, Properties, and its Antibacterial Applications

Currently, the overuse of antibiotics has led to the widespread dissemination of multidrug‐resistant bacteria, making the development of novel antimicrobial agents an urgent scientific challenge. 0D fluorescent nanomaterials (including carbon quantum dots, semiconductor quantum dots, and metal nanoclusters) exhibit outstanding antibacterial performance due to their unique nanoscale size effects, excellent biocompatibility, and remarkable surface‐area effects, positioning them as a promising solution against multidrug‐resistant bacterial infections. This review systematically summarizes the synthesis strategies and characteristic properties of these materials, with a focus on their antimicrobial applications in medical and health care, the food industry, agriculture, and industry. Furthermore, the advantages and current technical limitations of these emerging antimicrobial agents are critically discussed. The aim of this review is to provide a theoretical foundation for the rational design and development of nanoantibacterial materials while facilitating their translational applications in biomedicine.
