Multimodal lung cancer theranostics via manganese phosphate/quercetin particle

could activate the cGAS-STING signalling pathway and promote the maturation of dendritic cells and infiltration of activated T cells, thus inducing tumor immunogenic cell death (ICD). Furthermore, it exhibited effective T2-weighted MRI enhancement for tumor imaging, making them valuable for clinical diagnosis. In vitro and in vivo experiments demonstrated that AHA@MnP/QCT NPs enabled non-invasive imaging and tumor treatment, which presented a one-stone-for-two-birds strategy for combining tumor diagnosis and treatment, with broad potential for clinical application in non-small cell lung cancer therapy.
