Fluorescent Chemosensors for Zn²⁺ and Pyrophosphate

Abstract

Dual functions of napthoimidazole and naphthoimidazolium in the pre‐organized binding site were successfully applied to selectively detect Zn2+ and PPi via selective fluorescent changes.

Real-Time Fluorescence Screening Platform for Meat Freshness

“…As an emerging analytical method, fluorescent probes have gained increasing attention due to its advantages of simple operation, low cost, high specificity and sensitivity, rapid response, and real-time and visual monitoring of analyte. − Besides, small organic fluorescent probes have some other advantages: (1) chemical structure diversity. There are many types of chromophores such as rhodamine, fluorescein, coumarin, BODIPY, and so on.…”

Hydrogen sulfide‐activatable fluorescence turn‐on azide‐containing naphthalimide derivative

“…The H 2 S concentration‐dependent increase in fluorescence was observed at 0–40 μM of [H 2 S], and the increased fluorescence remained relatively unchanged at 50–250 μM of [H 2 S]. Based on these results, a linear plot of fluorescence improvement at 550 nm versus [H 2 S] (0–40 μM) was estimated, resulting in a limit of detection (LOD) 17,18 of Probe 1 for H 2 S as 2.29 μM (Figure 5b).…”

Dual-mode chemosensor for the fluorescence detection of zinc and hypochlorite on a fluorescein backbone and its cell-imaging applications

“…10 Therefore the development of various fluorescent chemosensors for the selective detection of Zn 2+ by in vitro and in vivo study has received great attention in recent years. 11,12 Though a number of excellent zinc sensors have been reported so far, the design of new sensors with better selectivity as well as sensitivity is still an active area of work. 13–19…”
