Effect of 4 °C incubation and sodium azide on the uptake of AuNRs with different modifications by cells. These cells were treated at 4 °C (gray bars) in the presence of sodium azide (closed bars) for 45 min. The cellular uptake of AuNRs was normalized to cells without inhibition treatment (open bars). Data represent mean values for n = 3, and error bars are one standard deviation of the means. Statistical significance: *P < 0.01 compared with values for treated cells at 4 °C and with sodium azide (student’s t-test).
