Several small molecular probes have been designed to detect singlet oxygen for the evaluation of PDT efficacy. However, little attention was paid to the precise visualization of the 1O2 signal at the subcellular organelle level in living biological systems. Herein, a super-pH-resolved (SPR) nanosensor was developed to specifically illuminate 1O2 in endocytic organelles through encoding the cell-impermeant singlet oxygen sensor green (SOSG) into pH-sensitive micelles. The acid-activatable SPR-SOSG achieved more than 10-fold amplification of the 1O2 signal, leading to extremely higher sensitivity of singlet oxygen detection in specific endocytic organelles of living cells and animals, as compared with the nonactivatable nanoprobe and the commercially available 2',7'-dichlorofluorescein diacetate (DCFH-DA) probe. Hence, the SPR-SOSG nanoplatform provides a promising tool to evaluate the efficacy and mechanism of nanocarrier-based photodynamic therapy.Nanopesticides were selected as one of the top 10 emerging technologies in chemistry that will change our world in 2019. Facile, smart, and degradable metal-organic framework MIL-101(FeIII) nanopesticides gated with FeIII-tannic acid (TA) networks are created using a universal strategy. The capping of the FeIII-TA network gatekeepers is instinctively oriented by the coordinatively unsaturated FeIII sites on the surfaces of the MIL-101(FeIII) nanocarriers; thus, their combination is perfectly matched. This is the first example that one smart gated nanoparticle is integrated with seven stimuli-responsive performances to meet the diverse co
