Quantification of the cellular uptake of PHBV nanoparticles: time dependency. To evaluate time dependency in the cellular uptake of NPs, HeLa (a), SKOV-3 (b) and PBMC (c) cells were incubated with a 100 µg/mL PHBV-RN at several times. d Mean fluorescence intensity analysis of the three different cells. Mean fluorescence intensity was determined by flow cytometry (n = 3)
