(a) UV-vis absorption spectra of the synthesized PEG-AuNPs with respect to . Inset shows color of synthesized PEG-AuNPs. (b-c) TEM images and their corresponding size distributions of the synthesized PEG-AuNPs synthesized at different −124.2°C/min (b) and 34.2°C/min (c). (d) UV-vis spectra of PEG-AuNPs recorded at 24 h with PBS and NaCl.
