Uptake of Single-Walled Carbon Nanotubes Conjugated with DNA by Microvascular Endothelial Cells

Figure 3

Intracellular compartmentalization and fluorescence intensity of SWCNT-DNA-FITC (10 μg/mL) and DNA-FITC (10 μg/mL) in microvascular ECs and observed at 6, 12, 24, and 48 hrs. (a) Representative projection images acquired by confocal microscopy; (b) Quantitative analysis of fluorescence intensity of SWCNT-DNA-FITC and DNA-FITC conjugates. The 𝑃 -values less than 0.05 and 0.01 are expressed as * and **, respectively ( 𝑛 = 3–12). The scale bar is applicable to all images.
