Abstract

Quantum dots (QDs) semi-conducting nanocrystals have found numerous applications in many fields of science. Nowadays one can observe a growing perspective to use them in biomedicine. Thanks to QDs unique fluorescence properties (narrow emission spectra, high extinction coefficients, high quantum yields, photostability) and possibility to form conjugates with bioactive molecules, they can become a chance for better cancer cells imaging in cancer therapy. Therefore there is a need for better understanding of biological interactions between QDs and cancer cells in vitro. For this purpose we performed cytotoxicity tests of CdSeS/ZnS quantum dots stabilized with mercaptopropionic acid (MPA) ligand, on human lung cancer cell line (A549) in vitro in macro- (96-well plate) and micro-scale (a specially designed and fabricated microfluidic device). The results obtained demonstrated a little extent of cytotoxic effect of selected solutions of QDs to A549 cells.
