Synthesis of Silver Nanoparticles from Plants and Their Applications

Nanobiotechnology defines applications of biosystems to produce novel functional materials. Production of metal nanoparticles is increasing to develop innovative technologies. There are various techniques to characterize the synthesized silver nanoparticles. UV-Vis spectroscopy is used for absorbance pattern, X-ray diffraction reveals crystalline nature with FCC geometry with mean particle size, Fourier transform infrared spectroscopy is for chemical compositions associated with NPs, and transmission electron microscopy is used to determine the shape of the NPs. AgNPs are one of the important materials having wide applications in optoelectronic devices, biosensors, and catalysis. Application of silver nanoparticles depends on the different charges, chemical composition, size, and shape. There are various methods to synthesize AgNPs. Keeping in view of synthesis and applications of AgNPs, a brief study of available literature for biosynthesis method and practices of silver nanoparticles has been reviewed.
