ABSTRACT
Nanomaterials can revolutionise the range and nature of various functions leading to an increase in demand day by day. Therefore, to fulfil this need, nanomaterials are being synthesized using various mechanisms. However, the large-scale synthesis of the nanoparticles and waste products released has raised the issue of toxicity to the environment affecting various flora and fauna of the ecosystem as well as human health. In recent years it has been observed that the biological synthesis of nanoparticles is cost-effective and eco-friendly as well as showing lesser toxicity in comparison to chemically and physically synthesized nanoparticles. Cytotoxicity can be checked using various in vivo and in vitro models. This chapter discusses the strategies for the biological synthesis of silver nanoparticles and their biological effects, including cytotoxicity.
