Fig. 1. (A) TEM images of DOX–AuGCs and (A1) histogram size nanoparticles (scale bars: 50 nm); (B) UV-Vis of DOX–AuGCs and (C) Raman spectra of-AuGCs (DOX and CTL–PEG diacide are also reported for comparison). The spectra were normalized on the intensity of the band at 990 cm−1. Experimental conditions: λexc = 785 nm; laser power 20 mW; 1200 Tof 180 s.
