Second near infrared (NIR-II) window fluorescence imaging between 1000–1700 nm with reduced scattering and autofluorescence, and deep tissue light penetration allows early and non-invasive determination of vascular pathologies. Here, we demonstrate in vivo NIR-II imaging techniques for tracking hyperglycaemia-induced Intracerebral Hemorrhage (ICH) and Blood Brain Barrier (BBB) hyperpermeability in Cerebral Cavernous Malformation (CCM) deficient mice (CCM1+/−). We synthesised PEGylated Ag2S quantum dots (QDs) with a bright fluorescent emission peak centred at 1135 nm under 808-nm NIR light for dynamic imaging of cerebral vasculature in mice and determined the development of ICH and BBB impairment in hyperglycaemic CCM1+/− mice. In vivo optical imaging was verified with micro-CT (including k-mean cluster analysis) as well as in vivo permeability assays using FITC-dextran perfusion and IgG staining, respectively. The increased BBB permeability in CCM1+/− mice was further demonstrated to be associated with high-glucose-caused decrease of CCM1 expression. This study validates that deep-penetrating NIR-II QDs can be used for the tracking of ICH and BBB hyperpermeability in transgenic mice models of cerebral vascular anomalies.
