Fig. 5From: Resveratrol-Loaded Albumin Nanoparticles with Prolonged Blood Circulation and Improved Biocompatibility for Highly Effective Targeted Pancreatic Tumor Therapy a Confocal fluorescence images of PANC-1 cells after incubation with HRP NPs, HRP–RGD NPs with RGD blocking, and HRP–RGD NPs labeled by FITC. Green and blue colors represent FITC fluorescence and DAPI stained cell nuclei, respectively. Scale bar = 20 μm. b The quantitative cellular uptake of PANC-1 cells towards HRP NPs, HRP–RGD NPs with RGD blocking, and HRP–RGD NPs by flow cytometryBack to article page
