Figure 4From: ATP driven clathrin dependent entry of carbon nanospheres prefer cells with glucose receptorsZeta potential of different cell type after treatment with CSP. Zeta potential of different cell types viz. U373 cells, HeLa and NIH3T3 cells were measured in 40 mM HEPES buffer (pH 7.4) upon 30 minutes, 2 hours, and 12 hours of incubation with 10 μg/ml of CSP.Back to article page
