The present manuscript deals the design and synthesis of some novel organobismuth compounds which are synthesized by the method reported earlier and characterized with the help of M.P., elemental and I.R. spectral analysis along with their antimicrobial studies, against different pathogenic bacterial and fungal strains and in-vitro antitumor activity against human breast (MCF-7) and mammary cancer (EVSA-7) cell line and found that compounds have potentiality as antitumor and antimicrobial agents.

Nanoparticles have attracted extensive scientific and industrial interest due to their unique electronic, optical, and catalytic properties. Many techniques such as chemical reduction radiolysis reduction of copper ions with supercritical fluids and thermal decomposition methods are developed to synthesize copper nanoparticles. The primary application of copper nanoparticles is catalysis, just like the bulk copper metal. On the other hand, copper nanoparticles offer higher catalytic efficiency per gram than the bulk one due to their large surface-to volume ratios. Copper and its oxide (Cu2O and CuO) nanoparticles were synthesized by using Copper(II) oxalate precursor and oleylamine as capping agent. Copper and its oxide Nanoparticles so obtained were characterized by UV- Visible spectroscopy, Fourier Transform Infrared Spectroscopy, and X-Ray diffraction analysis. X-Ray diffraction analysis proves the formation of Copper and its oxide Nanoparticles. SEM and AFM analyses show the presence of nanoparticles.
