Abstract :

The field of nanotechnology has recently witnessed spectacular advances in the methods of nanomaterial faication and utilizing their exotic physicochemical and optoelectronic properties. Nanoparticles exhibited “Brownian movement” in suspensions and the particle size distribution can be determined using scattering analysis. A. galanga derived AgNPs confirmed the particles size distribution about 169.9 nm. The zeta potential of the particles, however, strongly depends on the pH and the electrolyte concentration of the dispersion. Supporting the above statement, AgNPs dispersed in physiological saline was highly stable with a zeta potential value of âˆ’12.6 mV. Antimicrobial activity of biological compound was studied by agar well diffusion method, killing curve assay, DNA fragmentation analysis, SDS–PAGE and in silico interaction studies
