Summary: Hydrogen peroxide (H2O2), an important reactive oxygen species (ROS), is closely related to various pathological and physiological processes in living organisms. Excessive H2O2 can lead to diseases such as cancer, diabetes, and cardiovascular diseases, necessitating the detection of H2O2 in living cells. This study designed a new fluorescent probe that effectively detects H2O2 with high selectivity and measures cellular ROS levels, providing a potential monitoring tool for various diseases caused by H2O2 excess.

Summary: Reconstructing miniaturized peptides to mimic specific protein functions is appealing but challenging. In this study, we propose a practical approach to construct a mimetic peptide of redox-sensitive green fluorescent protein-2 (roGFP2) by rethreading aromatic residues adjacent to the chromophore fragment. By fine-tuning the residues, we designed a mini tetrapeptide (Cys-Phe-Phe-His) that acts as a hydrogen peroxide sensor using ratiometric fluorescence. The roGFP2 mimetic tetrapeptide, with its assembly-induced emissions, is biocompatible, photostable, and exhibits competitive fluorescent properties compared to roGFP2. We demonstrated the ability of the ratiometric tetrapeptide to sense hydrogen peroxide in acidic chambers, providing a promising approach for artificially designing miniaturized peptides with desired functions.

Summary: Fluorescent probes have been widely used as important tools for detecting H2O2 to reflect the physiological and pathological conditions of biological systems, with boronate ester and boronic acid groups serving as sensitive responsive parts in these probes. This review summarizes fluorescent probes based on boronate ester/boronic acid groups reported from 2012 to 2020, and classifies the fluorophores into six categories to elaborate the design strategy and systematic performance comprehensively.

Summary: A novel ESIPT ratio fluorescent probe (probe 1) has been proposed for detecting H2O2 in water environment and biosystems. Probe 1 exhibits short response time, high sensitivity, and a large Stokes shift to H2O2. It has been successfully used to detect H2O2 in actual water samples as well as endogenous and exogenous H2O2 in living cells, with wide applications in environmental and biological systems.

Summary: This study presents a single-component NIR-II ratiometric molecular nanoprobe (LC-1250 NP) for early monitoring of gastrointestinal diseases via oral administration. LC-1250 NP shows stable fluorescence in the 1250 nm long-pass channel before and after disease detection, but exhibits enhanced fluorescence in the 1150 nm short-pass channel in the diseased gastrointestinal environment due to the activation of LC-1250 molecules by H2O2. The ratio of fluorescence signals (F1150SP/F1250LP) linearly increases with the concentration of H2O2, providing accurate mapping of the diseased areas and reliable evaluation for the progress of gastroenteritis.
