Manganese (Mn)-based hybrid nanomaterials as theranostic agents and their application in tumor. (A) Schematic illustration of multifunctional nanocapsule and the systemic delivery of the self-sufficient theranostic nanoplatform (64). (B) Preparation and characterization of a core–shell MnS@Bi₂S₃-PEG nanostructure theranostic agents (70). (C) In vivo multimodal imaging (PA images, CT images, and MR images with the red circles mark the tumors) and corresponding signal analysis of tumor-bearing mice before and after intravenous injection of the monolayer bi-anchored Mn boride nanosheets (MBBN) (71). (D) In vivo therapeutic evaluation of FHCPC@MnO₂ nanoflowers (polyphosphazene coated onto Fe₃O₄ nanoclusters, with MnO₂ nanosheets as outer shell). Scale bar = 75 μm (72). PA, photoacoustic; FHCPC, coating multifunctional polyphosphazenes onto Fe₃O₄ nanoclusters and then growing manganese oxide nanosheets as outer shell; MBBN, Bi-anchored manganese boride nanosheets.
