Photographs and UV–Vis spectra of AuNPs15/HS–PEG3k–OMe (orange), AuNPs15/HS–PEG2k–SH (purple), and AuNPs15/c-PEG3k (red). a Before heating and after heating for b 4, c 8, d 12, e 24, and f 48 h at 85 °C. Rel. Abs was 2% for AuNPs15/HS–PEG3k–OMe, 64% for AuNPs15/HS–PEG2k–SH, and 75% for AuNPs15/c-PEG3k after 48 h.
