Macrophages are key factors in the formation of unstable atherosclerotic plaques, which may be identified through macrophage imaging. We tested whether activatable fluorescence probes of iron oxide nanoparticles (IONPs) conjugated with indocyanine green (ICG) (IONP-ICG), consisting of biocompatible reagents, can visualize macrophages present in atherosclerotic plaques.IONP-based probes conjugated...
Detecting detailed atherosclerotic plaques is important to reduce risk factors during surgery. However, there are few methods to evaluate them during surgery. The aim of this study was to establish an in vivo, non-contact, and label-free imaging method for identifying atherosclerotic plaque lesions from outside vessels with a diffuse-reflectance near-infrared (NIR) hyperspectral imaging (HSI) system...
