A colorimetric and fluorescent lighting-up sensor based on ICT coupled with PET for rapid, specific and sensitive detection of nitrite in food

Abstract

A colorimetric and fluorogenic sensor exhibiting rapid, specific and sensitive detection of potentially toxic nitrite in food is described.

Advances in fluorescent and colorimetric sensors for anionic species

“…52) [123]. A chemodosimeter for nitrite colorimetric and fluorometric sensing based on anthracene carboxyimide 59 was reported by Zeng, Niu, Kim and collaborators [124]. The recognition is based on the reaction between vicinal aryl diamines and NO2to form triazoles (Fig.…”

A novel highly specific colorimetric fluorescent probe for the detection of nitrite in aqueous solution

“…[ 4–7 ] However, NO 2 − ions are hazardous, and excessive NO 2 − ion intake causes serious harm to human health, such as poisoning, goiter, infant deformity, and even cancer. [ 3,8–12 ] With the aggravation of environmental pollution, the content of NO 2 − ions is also increasing rapidly in surface water and groundwater. The maximum contaminant level of NO 2 − ions is 3 ppm (65.1 μM) in drinking water, which is legislated by the World Health Organization.…”

Photoluminescent sea urchin-shaped carbon-nanobranched polymers as nanoprobes for the selective and sensitive assay of hypochlorite

“…In the eld of organic uorescent probes, D-p-A structured molecules are frequently designed to accomplish targetinduced emission colour changes through linking electronrich and electron-poor groups to p-conjugated spacers. 12,13 Inspired by this strategy, we decided to synthesize photoluminescent nanomaterials with similar structures via a facile approach for obtaining a high-contrast chromism.…”
