摘要:"In vitro or in vivo fluorescence imaging based on quantum dots (QDs) has shown promise for the nonin-vasive diagnosis of atherosclerosis. However, simultaneous in vitro and in vivo imaging remains challeng-ing due to the limitation of the current synthesis method of dual-emission QDs (dual-emitting hybrid QDs, and broad-spectrum emitting QDs). Herein, we fabricate a dual-emission (visible region and near -infrared region emission) QDs (ZAISe/ZnS) via the ""bottom to up"" method of a quaternary inorganic com-pound for the foam cells and atherosclerosis plaque imaging simultaneously without the intricate size modulation and the strict optical filter requirements. The oil-soluble ZAISe/ZnS is further encapsulated with bovine serum albumin (BSA) to realize phase transfer and ultimately possess the inflammation -targeting properties via biomimetic treatment with MMV (macrophage-derived micro-vesicle). The results first indicate that the as-constructed ZAISe/ZnS@BSA@MMV could accurately locate the foam cells and conduct long-term imaging of the atherosclerotic plaque, which provides a new strategy for the early and noninvasive diagnosis of atherosclerosis.
