Representative work: Atherosclerosis is a primary cause of cardiovascular and cerebrovascular diseases, with the unpredictable rupture of vulnerable atherosclerotic plaques enriched with lipid-laden macrophages being able to lead to heart attacks and strokes. Activating macrophage autophagy presents itself as a promising strategy for preventing vulnerable plaque formation and reducing the risk of rupture. In this study, we have developed a novel metal-free nanozyme (HCN@DS) that integrates the functions of multimodal imaging-guided therapy for atherosclerosis. HCN@DS has demonstrated high macrophage-targeting abilities due to its affinity toward scavenger receptor A (SR-A), along with excellent photoacoustic and Boron neutron capture therapy (BNCT) stands out as a noninvasive potential modality for invasive malignant tumors, with boron drugs playing a crucial role in its efficacy. Nevertheless, the development of boron drugs with biodegradability, as well as high permeability and retention effects, continues to present significant challenges. Here, we fabricate a size-tunable boron nanoreactor (TBNR) via assembling boron nitride quantum dots (BNQDs) and Fe3+ for tumor BNCT and chemodynamic (CDT) synergistic treatment. The obtained TBNR with an appropriate size exhibits superior tumor accumulation and retention. Upon stimulation by the tumor microenvironment (TME), the contained Fe3+ undergo redox re
