A novel fluorescence probe based on p-acid-Br and its application in thiourea detection

Abstract

A novel organic fluorescence system was developed to detect thiourea based on p-acid-Br, which in the range of 0.5–1000 nM and with a detection limit of 0.26 nM. And this method provides a new promising platform for clinical analysis.

Determination of Pb2+ in water using poly(pyrrole thiourea) electrode coupled with an electrochemical flow analysis device

“…Thiourea, which is the main raw material for medicine, pesticides, fertilizer, silk industry, agriculture, metal processing and so on [10a–c], has been reported that Pb 2+ could be highly absorbed by thiourea [11a–c]. Therefore, it could be considered that thiourea and pyrrole are simultaneously polymerized to form poly(pyrrole thiourea), and S atom of thiourea is introduced into the polymer to increase the active site of the polymer.…”

Thiourea Derivatives, Simple in Structure but Efficient Enzyme Inhibitors and Mercury Sensors

“…Fluorescence sensors employ a fluorescent signal for the detection of analytes. In order to detect different organics at an earlier stage of a disease development, a low detection limit of the organics is desirable [33]. Thiourea derivatives possess the ability to detect both anions and cations and are therefore attracting the attention to be versatile detectors in coming decades [5].…”
