Green synthesis of Cobalt Nanoparticles using Ethanolic extract of Cadiospermum halicacebium Characterisation and its anticancer applications

In the present study, cobalt nano particles were synthesized by an ecofriendly and cost effective method using Cadiospermum halicacebium leaf extract. The leaf extract acts as both reducing and capping agent. The biosynthesised cobalt nanoparticles were characterized by using various techniques such as UV-visible spectro photometry, Fourier transform infrared spectrometry, XRD and Scanning electron microscopy. The spectroscopic methods confirmed the formation of cobalt nano particles and the microscopic technique confirmed the shape and size of the cobalt nano particles. The anticancer activity of samples on Hela and VERO cell line were determined by the MTT assay.
