Caveolae-dependent endocytosis mediates the cellular uptake of CdTe quantum dots in ovarian cancer cell lines.

Background And Purpose: Quantum dots (QDs) are semiconductor nanocrystals that are widely used in biology due to their good optical properties. QDs, especially cadmium-based QDs, play an important role in the diagnosis and treatment of cancer due to their intrinsic fluorescence. The aim of the present study was the evaluation of the cellular uptake mechanisms of CdTe QDs in ovarian cancer cell lines.
