Fabrication of a photothermal antibacterial platform for bacterial infectious skin wound healing: a review

Abstract

Antibiotics are currently the main strategy to treat bacterial infections, but they can cause antimicrobial resistance. Thus, it is urgent to solve this problem. The emergence of photothermal therapy provides a new opportunity for the prevention and control of bacterial infection. In recent years, photothermal agents have been widely used in infection control and wound healing due to their strong antibacterial properties and low drug resistance. Photothermal agents (PTAs) are nanomaterials themselves, or small molecules loaded in nanoparticles, and are the basic elements of PPT. In this review, we discuss the characteristics of wound dressings in skin wound healing, types and main functions of antibacterial photothermal therapy (PTA), and the fabrication and application of wound dressings. Finally, the current challenges and future development of PTAs as a photothermal antibacterial platform for wound healing are summarized and discussed.
