Fig. 3From: One-step, Rapid and Green Synthesis of Multifunctional Gold Nanoparticles for Tumor-Targeted Imaging and TherapyXPS spectrum of the Au 4f of the (a) NLS-GNPs, (b) DRN-GNPs. The Au 4f7/2 binding energy of the original spectra (black) and fitted results (red) could be deconvoluted into two components, Au(0)-blue curve and Au(I)-purple curve. UV-Visible absorption spectra and images of DRN-GNPs dispersed in PBS, NaCl, NaOH, and HCl, respectively (c).Back to article page
