(a) LDI-MS spectra recorded using (A) AptMUC1–Au NPs (1.0 nM), (B) AptMUC1–Au NPs/GO ([AptMUC1–Au NPs] = 1.0 nM; [GO] = 0.25 g L–1), and (C) T45–Au NPs/GO [(T45–Au NPs) = 1.0 nM; (GO) = 0.25 g L–1] a probes for the detection of 105 MCF-7 cells. (b) Peak intensities of [Aun]+ ions obtained from (A) AptMUC1–Au NPs, (B) AptMUC1–Au NPs/GO, and (C) T45–Au NPs/GO after labeling of MCF-7 cells. (c) Concentrations of Au NPs accumulated in MCF-7 cells, as determined using ICP-MS. Other conditions were the same as those described in Fig. 1.
