Abstract
Rapid advances in nanotechnology have led to its emergence as a tool for the development of green synthesized noble metal nanoparticles, especially silver nanoparticles (AgNPs), for applications in diverse fields such as human health, the environment and industry. The importance of AgNPs is because of their unique physicochemical and antimicrobial properties, with a myriad of activities that are applicable in various fields, including the pharmaceutical industry. Countries with high biodiversity require the collection and transformation of information about biological assets into processes, associations, methods and tools that must be combined with the sustainable utilization of biological diversity. Therefore, this review paper discusses the applicable studies of the biosynthesis of AgNPs and their antimicrobial activities towards microorganisms in different areas viz. medicine and agriculture. The confirmed antiviral properties of AgNPs promote their applicability for SARS-CoV-2 treatment, based on assimilating the virus’ activities with those of similar viruses via in vivo studies. In this review, an insight into the cytotoxicity and safety issues of AgNPs, along with their future prospects, is also provided.

Nanotechnology represents a crucial turning point in the history of the universe
Kim et al (2007) used Muller Hinton agar plates to study the antimicrobial activities of AgNPs against E. coli, Staphylococcus aureus and yeast, showing that they are suitable for various medical devices and antimicrobial control systems [247]
The enhanced properties of green synthesized AgNPs can be exploited for use in almost all areas of science and everyday life, including preventing epidemics and treating contagious diseases
Summary
The endless desire and intelligence of humans have paved the way for groundbreaking inventions such as the internet, smartphones, rocket science, artificial intelligence and in vitro fertilization techniques, which carry many moral issues; for this reason, nanotechnology is a field of science that was previously considered to be controversial Overcoming these drawbacks, nanotechnology has emerged as an important tool in material science, which involves the fabrication, synthesis and manipulation of bulk molecules/particles in nanoscale dimensions. Nanotechnology has unlocked new opportunities in diverse sectors such as food packaging, the environment, animal husbandry, agriculture and healthcare, making it one of the most fascinating industrial phenomena of the modern era It is an Nanomaterials 2021, 11, 2086.
