The treatment of liver diseases is based on a clear understanding of the process underlying liver injury and repair. However, intravital real-time imaging of liver injury and repair is still limited due to the lack of in vivo reversible visualization methods. To this end, we proposed a rational design strategy for the development of reversible upconversion luminescence nanoprobe that allows real-time and in vivo imaging of liver injury and repair processes. As a proof of demonstration, we first developed a small molecule probe NB3 which can reversibly respond to related analytes of early liver injury (peroxynitrite, ONOO-) and liver repair (glutathione, GSH). The small molecule probe was then integrated with a core-shell upconversion nanoparticle to form a sophisticated nanoprobe. Compared to traditional small molecule probes, this nanoprobe exhibited higher selectivity to ONOO−, longer retention time in liver, and a wider response dynamic range to GSH after oxidized by ONOO−. The novel nanoprobe facilitated the successful monitoring and discrimination among the different degrees of liver injury and repair in a mouse model.
