Multi-scene visual hydrazine hydrate detection based on a dibenzothiazole derivative

“…Fluorescence analysis has the advantages of simple operation, real-time response, and rapid detection, and has been considered to be an excellent detection method in the fields of environment and biomedicine in recent decades. 19–25 According to different detection objectives, designing and preparing targeted fluorescent probes can effectively exploit the advantages of fluorescence analysis to achieve the detection of the established objectives. At present, some fluorescence probes have emerged for the detection of N 2 H 4 .…”

Rational Construction of a Two-Photon NIR Ratiometric Fluorescent Probe for the Detection of Bisulfite in Live Cells, Tissues, and Foods

“…In recent years, there are many analytical methods reported to measure bisulfite content. − Among these methods, a fluorescent probe has been recognized as a highly promising tool to detect bisulfite owing to its outstanding advantages, such as real-time application, high sensitivity, simple operation, and low cost. − Particularly, ratiometric fluorescent probes have been widely designed based on the Michael addition reaction, which shows two different fluorescence emissions that set up a built-in correction to eliminate interference from external factors. − However, the majority of them are excited by one photon, which makes their excitation wavelength so short that it inevitably causes self-fluorescence interference and then generates measurement deviation. Although some research groups have constructed two-photon fluorescent probes for bisulfite detection, their emissions were less than 650 nm, which restricted their further application. − Therefore, how to construct a two-photon near-infrared (NIR) fluorescent probe remains a big challenge worthy of further exploration.…”
