Biologically inspired nanoparticle synthesis is currently a rapid expanding area of research in nanotechnology. Nanoparticle synthesis utilizing the bioresources such as plants and microbes appears to be a viable, low-cost, and eco-friendly approach. Especially mushrooms can be used for largescale synthesis of silver nanoparticles as mushroom produces many proteins that reduce the silver nitrate during the biosynthesis. Silver nanoparticles can be characterized using ultraviolet-visible (UV-VIS) spectroscopy, fourier transform infrared spectroscopy, X-ray diffraction, scanning electron microscopy, energy dispersive X-ray, and transmission electron microscope. Silver nanoparticles possess high antibacterial activity since silver in different forms has been extensively used as a medicine for curing diseases and promote wound healing. Silver nanoparticles have high surface specific area, which will lead to excellent antimicrobial activity as compared with bulk metallic silver. Further, the silver nanoparticles show anticancer activity against various cell lines such as human epidermoid larynx carcinoma (HEP-2), colon adenocarcinoma (HCT-116), breast adenocarcinoma (MCF-7), liver carcinoma (Hep-G2), and intestinal adenocarcinoma (Caco2) were well documented. This review intends to present green synthesis of silver nanoparticles and their application as antimicrobial and anticancer agents.

In this present study, the green synthesized molybdenum (Mo5O14) nanoparticles (NPs) were successfully synthesized using the co-precipitation method using Eisenia fetida vermiwash extract and their application to the seed germination of Vigna radiata. UV visible spectroscopy and Fourier transform infrared spectroscopy (FTIR) confirm the formation of molybdenum nanoparticles and their interaction with the functional group of enzymes present in the vermiwah. The X-ray diffraction (XRD) study reveals that the crystallinity has a tetragonal shape and is 35 nm in size. A SEM study shows the formation of Mo5O14 NPs. The TEM and SAED patterns also exhibit a spherical shape with a size of 210.85 nm and polycrystalline Mo5O14 NPs. In order to evaluate the bio-potential properties of Mo5O14 NPs, seed germination studies were carried out with green gram (V. radiata) with different concentrations of Mo5O14 NPs and showed a positive influence on the germination of green gram. However, Mo5O14 NPs are being them as nanofertilizer in agriculture.
