An ultrasensitive and highly selective electrochemical method is described for the determination of dopamine (DA). It is based on the use of a multi-functional nanomaterial composed of water-soluble pillar[5]arene (WP5), dihydroxylatopillar[5]arene (2HP5)-modified gold nanoparticles (GNPs), and graphitic carbon nitride (g-C3N4), with an architecture of type 2HP5@GNP@WP5@g-C3N4. The modified GNPs were...
A novel chemiluminescence system for the determination of bismerthiazol is first described in this paper. It is based on the chemiluminescence reaction of bismerthiazol and Ce(IV) in nitric acid solution. The emission intensity could be enhanced greatly by Rhodamine B. The chemiluminescence intensity was proportional to bismerthiazol concentration over the range 30–1000 μg/L. The detection limit was...
