Abstract

The junction of nanotechnology and biomedical sciences unfasten the possibility for a wide range of biological research topics and medical uses at the molecular and cellular level. In the present study silver nanoparticles were synthesized by using Leucas aspera leaf extract support of biological process. The extract incubated with 1mM AgNO3 solution showed gradual change in the color of the extract from greenish to reddish brown. Reduction of silver ions by the leaf extract was examined by UV-visible spectroscopic technique. Further, it was confirmed by Fourier Transformations Infrared spectroscopic (FTIR) analysis. The purity of the synthesized silver nanoparticles was examined through X-Ray Diffraction (XRD) analysis. The nanoparticles were examined for the antibacterial activities of antibiotic (Tetracycline), silver nanoparticles and the combined effect of both antibiotic and nanoparticles against the multi drug resistant human pathogens.
