Elucidating lysosome polarity effect in complicated biosystems was impeded with the deficiency of lacking multi-disease models for researching the relation between lysosomal polarity and diseases. So far, dissecting the abnormal lysosome polarity in the inflamed and obese living mice has not been realized. To overcome this challenge, a robust probe MND-Lys was proposed for monitoring lysosomal polarity with two-photon emission. Using the probe, monitoring the intrinsic polarity variance in embryos and adult zebrafish has been achieved for the first time. Moreover, besides obviously discriminating tumors from normal ones, the probe also enabled tracing polarity changes in inflammatory and obese mice for the first time. The unique tracking and distinguishing polarity in lysosome make the probe a promising agent for fluorescence visualization studies of LD-lysosome related bioprocess and metabolism diseases.
