摘要

Cervical cancer remains one of the leading cause of cancer death in women. As the development of nanomedicine, multifunctional nanoplatforms which integrate imaging and therapy for effective diagnostics and therapeutics of cancer have attracted great attention in recent years. In this work, we have designed and developed a kind of multimodal imaging and treatment strategy which combined near-infrared (NIR) fluorescence imaging with magnetic resonance imaging (MRI) as well as photothermal therapy (PTT) via a multifunctional nanoplatform. The poly lactic-co-glycolic acid (PLGA) was utilized to encapsulate magnetic Fe3O4 nanoparticles (NPs) and NIR fluorescent dye clinical indocyanine green (ICG), by which integrated the advantages of Fe3O4 NPs and clinical ICG under 808-nm laser excitation, to achieve highly efficient dual-modal imaging-guided cervical tumor ablation. This work provides a promising approach for multimodal imaging diagnosis and PTT of cervical cancer.
