Tumor-associated mast cells (TAMCs) have been recently revealed to play a multifaceted role in the tumor microenvironment. Noninvasive optical imaging of TAMCs is thus highly desired gain insights into their functions cancer immunotherapy. However, due lack single enzyme that specific cells, common probe design approach based on single-enzyme activation not applicable. Herein, we reported bienzyme-locked molecular (THCMC) photoinduced electron transfer-intramolecular charge-transfer hybrid strategy for vivo TAMCs. The mechanism ensures THCMC exclusively turns near-infrared (NIR) fluorescence only presence both tryptase and chymase specifically coexpressed by cells. Thus, effectively distinguishes from other leukocytes, including T neutrophils, macrophages, capability lacking single-locked probes. Such high specificity allows noninvasive tracking fluctuation living mice during results reveal decreased intratumoral signal after combination immunotherapy correlates well with reduced population TAMCs, accurately predicting inhibition growth. this study presents first NIR fluorescent but also proposes generic cell imaging.
