In the present research program, cost effective and environment friendly gold nanoparticless were synthesized using the onion (Allium cepa) extract as the reducing agent. The nanoparticless were characterized using UV-visble, XRD, and SEM, TEM methods. The absorption peak at 540 nm was found to be broaden with increase in time indicating the polydispersity nature of the nanoparticles. The XRD results suggested that the crystallization of the bio-organic phase occurs on the surface of the gold nanoparticles or vice versa. The broadening of peaks in the XRD patterns was attributed to particle size effects. The internalization of nanoparticles within cells could occur via processes including phagocytosis, fluid-phase endocytosis and receptor mediated endocytosis.
