Metallic nanoparticle-based strategies for COVID-19 management in the post-pandemic era

Nanotechnology has emerged as a transformative tool in modern medicine, playing a vital role in the fight against infectious diseases. With the global spread of COVID-19, innovative nanomaterial applications became indispensable for enhancing diagnostic, therapeutic, and preventive strategies. In this context, the distinctive properties of some MNPs, such as surface plasmon resonance (SPR), have been harnessed for biomolecule identification and analysis of macromolecule interactions. The antiviral and antibacterial efficacy of MNPs is largely determined by their physical and chemical characteristics. Through this chapter, the applications of MNPs during the COVID-19 pandemic have been explored. Various in vivo, in vitro, and in silico studies have been analyzed, showing positive results for their application in therapeutics, diagnosis, personal protective equipments, and among others. This chapter has highlighted the potential and versatility of MNPs in virus detection, treatment, and disinfection. Continued research will not only make these technologies more available to a wider population but also ensure their production is environmentally responsible and economically viable.
