제목 IR-780 dye loaded Zwitterionic Micellar Nanoparticle for NIR imaging and Photothermal therapy in a Cervical tumor model.
초록 PEGylation of nanoparticles supports in long term circulation of nanoparticle in blood stream, although it limits the intracellular uptake of nanoparticle. Hence, we developed a micellar nanoparticles using the amphiphilic zwitterionic polymer-lipid synthesized via RAFT polymerization, and encapsulated with IR-780 dye (PCB-lipid–IR-780). The nanoparticle exhibited low cytotoxicity and remarkable photothermal cytotoxicity to cervical cancer cells (TC-1) upon near-infrared (NIR) laser irradiation. The PCB-lipid–IR-780 nanoparticle showed higher accumulation in tumor and following NIR laser irradiation of the tumor region resulted in enhanced tumor ablation and subsequent tumor regression in the TC-1 xenograft model. Hence, these zwitterionic polymer-lipid hybrid micellar nanoparticles show great potential for cancer theranostics and might be beneficial for clinical applications.
