RESUMEN
Globally, concerns regarding the COVID-19 pandemic its prevention have become important. Because of COVID-19 and other microbial diseases, enhance research work has emerged revealing new antimicrobial and antiviral materials and techniques. Tremendous growth in nanotechnology has opened up the door to fabricating numerous nanomaterials. These nanomaterials are employed as antimicrobial and antiviral agents for various applications with 99.99% effectiveness compared with conventional techniques. Nanoparticles possess unique physicochemical characteristics for multiple applications. This chapter details the use of nanoparticles for antifungal, antimicrobial, and antiviral applications. It describes various kinds of nanoparticles, such as nanometals, metal oxides, polymeric nanomaterials, and carbon-based nanomaterials. © 2023 Elsevier Inc. All rights reserved.
