Figure 2. Uptake values of various types of gold nanoparticles for cells positioned in the upright and inverted configurations.

Figure 2

The number (N) of particles taken up per cell was measured for both the as-prepared and PEGylated samples using the UV-vis method. The nanoparticles and their concentrations (based on particle number) used to incubate with the cells were: a, 15-nm nanospheres (120 pM); b, 54-nm nanospheres (20 pM); c, 100-nm nanospheres (2.8 pM); d, 62-nm nanocages (20 pM); e, 118-nm nanocages (2.6 pM); and f, nanorods (20 pM). Error bars shown in the plots are standard errors with n=4.
