Radiation preparation and application status of photosensitive antibacterial composite hydrogel

Abstract

Hydrogels comprise hydrophilic polymer networks. Owing to their good biocompatibility and hydrophilicity, they are widely used in wound dressings, drug delivery, tissue engineering, bioreactors, contact lenses, and other fields. This article summarizes some typical photocatalysts, photosensitizers, and hydrogel composite materials and their antibacterial activities, as well as the basic mechanisms of photothermal and photodynamic effects. In addition, the advantages of radiation technology for preparing photosensitive antibacterial hydrogels are discussed in detail, along with the applications of hydrogels in various fields and the challenges in their use. Finally, future development of photosensitive antibacterial hydrogels is discussed.
