Fluorescence intensity of AuNPs-Cy5.5-A&C in C6 cells. A Image of C6 cells incubated with AuNPs-Cy5.5-A&C and other probes for 24 h. 20 μM Atorvastatin (Ato) was added to inhibit AEP activity. The bottom pictures were bright-field (BF) images of C6 cells of each group. B Fluorescent intensity of AuNPs-Cy5.5-A&C and other probes in C6 cells was measured by flow cytometry analysis. *P < 0.05, **P < 0.01 between groups as indicated; one-way ANOVA, n = 3 independent experiments. C Viability of C6 cells after 24-h incubation with various nanoparticles. n = 3 independent experiments
