The current trend highly favors the synthesis and production of metallic
nanoparticles such as gold, silver, copper, zinc, iron, magnesium etc. utilizing plant
components that have superior properties. Simultaneously nanoparticles have been
produced utilizing diverse plant extracts sourced from leaves, roots, seeds and other
plants. Plant-extract-based nanoparticles are in high demand due to their outstanding
characteristics and versatile applications. These nanoparticles are extensively employed
in numerous medical procedures, devices and biological applications they do present
drawbacks attributed to nanotoxicity. This review offers a comprehensive view of the
mechanism of action, production, and medical applications of nanoparticles particularly
focusing on their potential health and environmental impacts. This study discusses
medicinal plants, plant- extract-based nanoparticles and their potential uses for
antiviral, anticancer, antibacterial, and antifungal treatment.
Keywords: Antibacterial, Anticancer, Mechanism of action, Nanoparticles.
