From: Peptide-biphenyl hybrid-capped AuNPs: stability and biocompatibility under cell culture conditions
TEM images of AuNPs in EMEM/S- after preparation. (a) Au[(TrCys)2B], (c) Au[(Gly-Tyr-TrCys)2B] and (e) Au[(Gly-Tyr-Met)2B], and at 24 h of incubation; (b) Au[(TrCys)2B], (d) Au[(Gly-Tyr-TrCys)2B] and (f) Au[(Gly-Tyr-Met)2B] [Scale bar (c) and (d) is 20 nm, and for all other images, scale bar is 50 nm]; asterisk and bold letters are used to signal the most stable AuNP.
