Characterization of amphiphilic gold nanorods. (a) UV-visible spectra of gold nanorods (AuNRs) stabilized by cetyltrimethylammonium bromide (CTAB) in water (green line) and AuNRs coated with PEG and polylactide (AuNR@PEG/PLA) (Mn (PEG) = 5,000, Mn (PLA) = 13,000) in chloroform (orange line). (b) GPC traces of the PLA brush detached from amphiphilic AuNR@PEG/PLA, with a molecular weight of Mn = 13,000. (c) 1H-NMR of AuNR@PEG/PLA with PEG:PLA molecular ratios of 1:3 (green line), 1:4 (black line) and 1:5 (blue line). (d) TGA characterization of AuNR@PEG/PLA (the weight fraction of the organic polymer is 13.5%). Image adapted with permission from ref. 35, American Chemical Society.
