Near-infrared image-guided delivery and controlled release using optimized thermosensitive liposomes.

abstract：PURPOSE:The objective of this study was to evaluate nanoparticle uptake by the Caco-2 monolayer model in vitro. Special emphasis was placed on the localization and the quantification of the uptake of fluorescently labeled polystyrene and poly(lactic-co-glycolic acid) (PLGA) nanoparticles. METHODS:Intracellular fluores...
