Nanoparticles; Their Use as Antibacterial and DNA Cleaving Agents

Abstract

Nanoparticles have revolutionized the field of nanotechnology, owing to their specialized characteristics. The immense use of nanoparticles in various fields has led to the great demand in terms of production as well as the fabrications methods. Apart from conventional methods, the use of environmental friendly methods had gained much impetus, particularly, using biological material, including plant extracts. The obtained metals based nanoparticles are applied in innumerable areas including drug discovery, antibacterial and DNA cleaving agents, while as DNA cleaving ability of nanoparticles is to be explored extensively. The various nanoparticles generated have been characterized by different spectroscopic, optical and thermal techniques to establish their precise structure and size. Thus, this chapter reports the importance of nanotechnology in the form of nanoparticles based on their various modes of synthesis, their biological significance in terms of targeting microbes and DNA.
