The emergence of multi-resistant bacteria to drugs is recognized as a major cause of the increasing
number of deaths in hospitals. Killing these bacteria require multiple expensive drugs that
can have side effects. Metal nanoparticles may provide a new strategy to combat them. Due the antimicrobial
and antiviral properties, nanoparticles (NPs) have outstanding biological properties that can be handled properly
for desired applications. This review presents antibacterial and antiviral activity of metal NPs, including the molecular
mechanisms by which NPs annihilate multidrug-resistant bacteria.
Keywords: Antibacterial, Antiviral, Drug-multiresistant bacteria, Molecular mechanism.
