Synthesis of PEG-Iodine-Capped Gold Nanoparticles and Their Contrast Enhancement in In Vitro and In Vivo for X-Ray/CT
Figure 5
X-ray photoelectron spectroscopic (XPS) data for the methoxy PEG-capped AuNPs (sample-1) and the methoxy PEG-iodine-capped AuNPs (sample-2). These data show the change of binding energy of gold and iodine.
