Figure 2

Cellular uptakes of CPBs 2 and SPNPs 2. (a) CLSM images of A549, SH-SY5Y, and HUVEC cells after 4 h incubation with the FITC-labeled CPBs 2 and SPNPs 2 at 37°C, respectively. Scale bars = 20 μm. (b) Mean fluorescence intensity (MFI) in A549, SH-SY5Y, and HUVEC cells measured by flow cytometry after 4 h incubation with the FITC-labeled CPBs 2 and SPNPs 2 at 37°C, respectively. Data as mean values ± SD (n = 3). P < 0.001 (CPBs 2 versus SPNPs 2).
