The aim of this research is to study the dynamics and efficiency of liposome accumulation in sensitive and resistant human breast cancer cells. Methods: Methods of fluorescence microscopy, fluorescence microspectroscopy and MTT-test have been used. Results: The liposome-to-cell interaction and dye cellular uptake in sensitive, cisplatin-resistant and doxorubicin-resistant MCF-7 human breast cancer cells have been analyzed using time changes in both fluorescence resonance energy transfer signal from the donor probe DiO to the acceptor one DiI preloaded in liposomes and cell image brightness. Conclusion: Obtained results show that resistant cells accumulate dye-loaded liposomes more effectively and reveal more effective dye molecule cellular uptake.
