Native polyacrylamide gel electrophoresis characterization of ultrasmall AuNPs in biological media. Data were obtained for (a) AuMBA, (b) AuGSHzwt, (c) AuGSHzwt@1st and (d) AuGSHzwt@10st in PBS, 40 mg/mL BSA and fetal bovine serum (FBS). The AuNPs were pre-incubated in the different media for 1 h prior to loading into the gel. The percentage of acrylamide in the running and stacking gels were 15 and 5%, respectively. Arrows mark the interface between the stacking and running gels where AuMBA and AuGSHzwt@10st accumulate.
