Cellular uptake of nanoparticles with fluorescence labeling. (A) Confirmation of DiR hybrid nanoparticles. All the nanoparticles were separated by centrifuge and filtration, the fluorescence intensity was detected by resolved precipitate in solvent, which showed almost all DiR successfully hybrid into nanoparticles with only a few free DiR left in suspension; (B) Comparison of cellular uptake of PDN and PDNM on various cell lines, visualized by DiR fluorescence imagining.
