Figure 3From: Contact-mediated intracellular delivery of hydrophobic drugs from polymeric nanoparticlesFlow cytometry histograms illustrating cellular uptake and inhibition of uptake of Nile Red. Cells incubated with nanoparticles for 3 h together with endocytosis inhibitors chlorpromazine or genistein (a) and cells incubated at 37°C or 4°C with either nanoparticles or free Nile Red for 1 h (b).Back to article page
