Abstract

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.

Keywords: Silver nanoparticles, bio reduction, bio-encapsulation substances, bionanofactories, applications in biomedicine, green synthesis.
