Figure 11

Near infrared fluorescence images of the ICG encapsulating HBPH nanoparticles (Fol-ICG-HBPH NPs) incubated with A) MCF 7 and B) A549 cells, indicating receptor-mediated internalizations of our theranostic HBPH nanoparticles. Images taken from a Xenogen IVIS system using ICG filter set. Each well contains an increasing amount (from left to right, 20, 40, 60 80 µL) of Fol-ICG-HBPH NPs (3.2 mg/mL), which translate into an increasing uptake of nanoparticles and higher fluorescence emission.
