  Abstract:

  We synthesized AuPt alloyed nanoparticles in colloidal solution   by a one-pot procedure based on synchrotron x-ray irradiation in   the presence of PEG (polyethylene glycol). The exclusive presence   of alloyed nanoparticles with fcc structure was confirmed by   several different experiments including UV–vis spectroscopy,   x-ray diffraction (XRD) and transmission electron microscopy   (TEM). The composition of the AuPt alloyed nanoparticles can be   varied in a continuous fashion by simply varying the feed ratios   of Au and Pt precursors. The nanoparticles exhibited colloidal   stability and biocompatibility, important for potential   applications.
