Abstract	Nanotechnology has emerged as the most attractive field of research due to its significant benefits for all fields of science. Lately, tin oxide has gained a lot of interest because of its unique properties, that were recently enhanced through nanometer-scale synthesis. Tin oxide (SnO2) nano particles (NPs) are used in many areas such as catalytic, electrochemical, and biomedical applications. Tin oxide nanoparticles not only exhibit promise in water treatment but demonstrate potential applications in cancer therapy. In this work, Tin oxide nanoparticles were successfully synthesized through a wet chemical method using jasmine leaves extract. The synthesized tin oxide nanoparticles, SnO2 – ZnO and SnO2 – PEG nano composites were prepared and characterized by Fourier transform infrared spectroscopy (FTIR) to figure out the functional groups present. UV–visible spectroscopy was used to characterize SnO2 NPs, and the values showed at 234-275 nm wavelengths and 0.294 absorbance(Abs), SnO2 – ZnO nano composite the values showed at 279- 382 nm and 1.363-1.358 abs and SnO2 – PEG nano composites the value showed at 307 nm and 0.140 Abs. Tin oxide nanoparticles and SnO2 – ZnO nano composite, SnO2 – PEG nano composite were characterized by Transmission electron microscopy studies (TEM). The results showed nano size and crystalline, and the presence of spherical morphology and fringes demonstrated the crystallographic orientation relationship. The electrical conductivity was identified and characterized for SnO2 NPs, SnO2 – ZnO and SnO2 – PEG nano composites. Tin oxide nanoparticles and the two composites were screened for antimicrobial activity and were tested on Escherichia coli, Staphylococcus aureus and Streptococcus pyogenes. And they are promising candidates for bio medical applications.
