The research progress of organic fluorescent probe applied in food and drinking water detection

A Simple Turn-off Schiff Base Fluorescent Sensor for Copper (II) Ion and Its Application in Water Analysis

“…In recent years, fluorescent probes have been widely used in the field of rapid detection (food, metal ion, anion, biomarker, etc.) due to advantages such as ease of operation, low cost, high selectivity, and sensitivity [ 1 , 2 , 3 , 4 ]. Copper is an earth abundant element which plays an important role in many domains like industrial material, [ 5 ] bactericide, and herbicide [ 6 , 7 ], etc.…”

A ratiometric fluorescent probe for the detection of β-galactosidase and its application

“…To validate this method, the b-gal activity in these samples was tested using the b-galactosidase spectrophotometric method. 40,41 The b-gal activity of all samples was 0 U mL À1 . No bgal activity was detected in the kiwi (ripe) sample by the GB/T 33409-2016 method; this could be because the b-gal activity in kiwis (ripe) and the LOD of this method are of the same order of magnitude.…”

“…[37][38][39] However, uorescent probes used in fruit detection are extremely rare in scientic literature. 40,41 To develop a simple detection method for b-gal activity in fruit, a ratiometric uorescent probe (Probe 1) with high accuracy and detection precision was developed. This ratiometric uorescent probe has the characteristics of high accuracy and strong anti-interference.…”

A smartphone-adaptable fluorescent sensing tag for non-contact and visual monitoring of the freshness of fish

“…Fluorescent probes for food detection and quality monitoring have attracted great attention in recent years due to the advantages of high sensitivity and selectivity, and in situ fluorescence imaging. 22 Some fluorescent sensors with various recognition sites including aldehydes, 15,23 carboxylic acids, 17,24 esters, 19,19 and pyrylium salts, 21,25 were prepared for the sensing of biogenic amines. However, most of these sensors showed poor selectivity and low sensitivity, and can work only in solution, which limited their applicability.…”
