Ligand enhanced cellular uptake in BON cells measured by flow cytometry and CLSM. (A) Flow cytometry revealed that intracellular uptake of micelles labeled with DOX (2 h incubation, DOX concentration: 1 μg/mL), was 4 times higher for OCT-conjugated micelles comparing to their non-targeted controls. (B) CLSM images showed that OCT conjugated nanocarriers had faster cellular uptake after 2 h incubation (DOX concentration: 1 μg/mL).
