 Antimicrobial nanoparticles are gaining increasing attention due to their unique properties such as high surface area, enhanced reactivity, and functionalizable structure. These particles can be used to deliver antibiotics or other antimicrobial agents to targeted sites within the body, thus providing a more efficient and controlled method of treatment than traditional methods. Metal, metal oxides, and other types of nanoparticles have been studied extensively for their antimicrobial activity. This review focuses on the development of nanoparticle-based therapeutic strategies against infectious diseases, highlighting the advantages of using nanoparticles for antimicrobial drug delivery.
