A Fluorescent Probe based on a Carbazole Derivative for Detecting Brilliant Blue in Food
Here a fluorescent probe based on a carbazole derivative (CNS) was developed to increase the detection range and reduce the detection limit of brilliant blue. Characteristics of CNS are studied. Due to the quenching ability of colorants, CNS shows an excellent current response to brilliant blue (from 1 to 10 µM) with a detection limit of 2.7×10−8 mol/L (3σ/k) in the conditions of a 1:1 volume ratio of water to tetrahydrofuran. And the stability and reproducibility of CNS in the detection of actual samples indicate great potential for application.
