ABSTRACT

Nanotechnology is one of the upcoming imperative fields of research in the present scenario. Nanomaterials can be produced by a variety of physical and chemical methods, which in turn creates biological and environmental risks due to the toxicity of the used chemicals. Perhaps it is more prominent nowadays to adopt biosynthesis process via green chemistry based techniques. Biosynthesis is an emerging method of green and safe technique for the synthesis of nanoparticles using biological entities such as various plants and microbes as a source of precursor material. However, using the various plant extracts for synthesis purpose is more beneficial over using microbes due to the ease of use and fewer biohazards. These nanoparticles play a pivotal role in many fields, especially in biomedical applications. Therefore, the small nanoparticles are showing the applications in bioimaging, biotransformation, sensor, anticancer, antifungal, antioxidant, antibacterial, and antimicrobial activity. In this chapter, we examine to explore the biosynthesis of nanoparticles such as gold, silver, titanium, copper, zinc, iron, selenium, and platinum. The aim of this chapter is afford an impression of recent trends in synthesizing nanoparticles via biosynthesis entities and their various characterizations techniques, properties, and potential cancer therapeutic applications.
