Polymeric Nanogels for Antimicrobial Therapy

At present, the development of antimicrobial systems requires ongoing and consistent improvement in their efficacy and versatility. Polymeric nanogels can serve as an efficient tool for this purpose, as they have become an excellent alternative for the design of tissue engineering and bone regeneration scaffolds, in addition to vehicles for the delivery of drugs or active substances, and they have recently been investigated as wound dressings. Nanogels have also been shown to be an excellent alternative for nanomedicine due to their antimicrobial activity and specific properties, such as swelling, biocompatibility, and biodegradability. In this review, we present an analysis of the use of polymeric nanogels for antimicrobial therapy and provide a discussion focused on different types of nanogels and their advantages and disadvantages, which will serve as a reference point for the future development of nanogels with antimicrobial properties. We also focus on the analysis of the different methodologies employed to prepare nanogels.
