Red-blood-cell-membrane-enveloped magnetic nanoclusters as a biomimetic theranostic nanoplatform for bimodal imaging-guided cancer photothermal therapy

Abstract

-weighted magnetic resonance imaging (MRI) signal of MNCs. Furthermore, upon exposure to 808 nm laser irradiation, the tumors grown on the mice with the intravenous injection of Cyp-MNC@RBCs show a higher temperature increase than the tumors grown on the mice injected with plain MNC@RBCs and thus are significantly suppressed via photothermal ablation. This study presents the preparation of biomimetic Cyp-MNC@RBCs with greatly improved tumor-homing capacity as multifunctional nanotheranostic agents for fluorescence and MRI bimodal imaging-guided cancer photothermal therapy.
