The green synthesis of silver nanoparticles has garnered significant interest because of
the unique physicochemical and biological properties they possess. These nanoparticles could have
applications in a wide variety of fields, including biomedicine, cellular imaging, cosmetics,
healthcare tourism, food and agriculture. The formation of nanoparticles is facilitated by the use of
bionanofactories, or green synthesis processes, which utilise living organisms, biomolecules, and
plant-based materials as bio reductive or bio sealing agents. Green chemistry is cost-effective in addition to being environmentally friendly, non-toxic, and biodegradable. By considering the results
of recent studies using techniques like scanning electron microscopy, transmission electron microscopy, atomic force microscopy, ultraviolet/visible spectrophotometry, Fourier transform infrared
spectroscopy or X-ray diffraction, we illuminate the most recent advances in green synthesis and
the physicochemical properties of green silver nanoparticles. We also discuss the properties of silver nanoparticles that make them effective against bacteria, fungi, and parasites.
