Size distribution and morphology of AuC18 and AuC20 NPs. (a) Size distribution of AuC18 and AuC20 NPs, as determined by measuring the diameter of at least 200 NPs on TEM images, is presented as frequency distribution (size [nm] versus % of AuNP with a particular size) and as whiskers. (b) Representative TEM images of the AuC18 and AuC20 taken 1 day or 3 months after the synthesis by modular USP.
