Gold nanoparticles (AuNPs), due to their unique properties and surface modification abilities, have become a promising carrier for a range of biomedical applications. AuNPs have intrinsic antiviral characteristics because of their capacity to enhance drug distribution by making antiviral medications more stable and soluble, which assures that higher quantities reach the intended site. Through surface changes, AuNPs can bind directly to viral particles or infected cells, increasing therapeutic efficiency and reducing side effects. AuNPs efficiently damage cell membranes and hinder viral reproduction within a host cell. Furthermore, because of their large surface area-to-volume ratio, which enables many functional groups to connect, improving interaction with virus particles and ceasing their multiplication. By altering dimensions and morphology or conjugating it with additional antiviral drugs, AuNPs can array their synergistic antiviral activity. Thus, the development of AuNP conjugated therapy presents a promising avenue to address the demand for novel anti-viral therapeutics against infections resistant to several drugs.
