Cypate-mediated thermosensitive nanoliposome for tumor imaging and photothermal triggered drug release.

It is an emerging focus to explore controlled release drug delivery systems for simultaneous cancer imaging and therapy. Herein, we synthesized a photothermal sensitive multifunctional nano-liposome drug delivery system, with doxorubicin wrapped in the hydropholic layer as the therapeutical agent and cypate doped in the hydrophobic layer as the diagnostic agent. A series of in vitro and in vivo characterization demonstrated the stability of synthesized liposome, as the DL% was 9 ± 1.5 and the EE% was 82.7 ± 2.1. And the liposome achieved the functions of target-delivery, enhanced photochemical internalized drug release, and simultaneous chemotherapy and thermal therapy, indicating that this multifunctional nano-liposome is a promising drug delivery system for tumor diagnosis and targeting therapy.
