Fluorescent probes that emit in the far-red (600–700 nm), first near-infrared (NIR-I, 700–900
nm), and second NIR (NIR-II, 900–1700 nm) regions possess unique advantages, including …

Hydrogen sulfide (H2S) is not only a well-established toxic gas but also an important small
molecule bioregulator in all kingdoms of life. In contemporary biology, H2S is often classified …

In this work, a phenothiazine-based fluorescent probe (PR) has been developed for the
selective detection of hydrogen sulfide (H2S) in biosystems and monitoring H2S produced in …

The active sulfur small molecules such as biothiols, hydrogen sulfide, hydrogen polysulfides
and sulfur dioxide are closely related to various diseases in the biological system and have …

Recent studies suggest that inorganic hydrogen polysulfides (H2Sn, n≥ 2) play important
regulatory roles in redox biology. Modulation of their cellular levels could have potential …

Hydrogen polysulfide (H2S n), derived from hydrogen sulfide (H2S), has attracted increasing
attention, which is suggested to be the actual signal molecule instead of H2S in …

Hydrogen polysulfide (H 2 S n, n> 1) is an important component of reactive sulfur species
(RSS), which is an important substance for maintaining the redox balance in cells. However …

Reactive sulfur species (RSS) play important physiological and pathological roles in
biological redox homeostasis, cell signaling and the regulation of metabolism. Recent …

Hydrogen polysulfide (H 2 S n) is an emerging topic of research because it plays a critical
role in the pathological and physiological activities of an organism. Therefore, visual …

The development of probes for rapid, selective, and sensitive detection of the hydrogen
polysulfides is of great importance in biological science. We report here a new Near-infrared …
