摘要：The threat posed by antibiotic-resistant bacteria and the challenge of biofilm formation has highlighted the inadequacies of conventional antibacterial therapies, leading to increased interest in antibacterial photodynamic therapy (aPDT) in recent years. This approach offers advantages such as minimal invasiveness, low systemic toxicity, and notable effectiveness against drug-resistant bacterial strains. Porphyrins and their derivatives, known for their high molar extinction coefficients and singlet oxygen quantum yields, have emerged as crucial photosensitizers in aPDT. However, their practical application is hindered by challenges such as poor water solubility and aggregation-induced quenching. To address these limitations, extensive research has focused on the development of porphyrin-based nanomaterials for aPDT, enhancing the efficacy of photodynamic sterilization and broadening the range of antimicrobial activity. This review provides an overview of various porphyrin-based nanomaterials utilized in aPDT and biofilm eradication in recent years, including porphyrin-loaded inorganic nanoparticles, porphyrin-based polymer assemblies, supramolecular assemblies, metal-organic frameworks (MOFs), and covalent organic frameworks (COFs). Additionally, insights into the prospects of aPDT is offered, highlighting its potential for practical implementation. Antibacterial photodynamic therapy (aPDT) has gained increasing interest due to its minimal invasiveness, low toxicity, and effectiveness against drug-resistant bacteria. Porphyrins, as key photosensitizers in aPDT, face challenges of poor solubility and low photodynamic efficiency caused by aggregation. This review highlights the development of porphyrin-based nanomaterials including nanoparticles, polymer nano-assemblies, supramolecular nano-assemblies, MOFs, and COFs, to enhance aPDT efficacy and antimicrobial activity. image
