Ultrasound assisted poly(ethylene glycol) templated bismuth oxynitrates modified screen printed electrodes for dopamine electrochemical detection

2025

Abstract

Abstract The detection of dopamine represents an intriguing and relevant field of application for electrochemical sensors. The sensors tailored with inorganic species are of great interest due to their high tuneability in both morphology and chemical features. In this work, we investigate the effect of different amounts of poly(ethylene glycol) used as template agent for ultrasound assisted synthesis of bismuth oxynitrates on composition and morphology. We found that the increase in poly(ethylene glycol) induced a surface defectiveness on bismuth oxynitrate boosting electrochemical sensing performances reaching sensitivity of up to 16 μA/mM and LOD close to 2 μM and achieving a sixfold increase in the electron transfer rate compared with the bare electrode.

Ethylene glycol

Ethylene glycol (IUPAC name: ethane-1,2-diol) is an organic compound (a vicinal diol) with the formula . It is mainly used for two purposes, as a raw material in the manufacture of polyester fibers and for antifreeze formulations. It is an odorless, colorless, flammable, viscous liquid. Ethylene glycol has a sweet taste, but it is toxic in high concentrations. This molecule has been observed in outer space. Ethylene glycol is produced from ethylene (ethene), via the intermediate ethylene oxide.

Ethylene oxide

Ethylene oxide is an organic compound with the formula . It is a cyclic ether and the simplest epoxide: a three-membered ring consisting of one oxygen atom and two carbon atoms. Ethylene oxide is a colorless and flammable gas with a faintly sweet odor. Because it is a strained ring, ethylene oxide easily participates in a number of addition reactions that result in ring-opening. Ethylene oxide is isomeric with acetaldehyde and with vinyl alcohol. Ethylene oxide is industrially produced by oxidation of ethylene in the presence of a silver catalyst.

Diethylene glycol

Diethylene glycol (DEG) is an organic compound with the formula (HOCH2CH2)2O. It is a colorless, practically odorless, and hygroscopic liquid with a sweetish taste. It is a four carbon dimer of ethylene glycol. It is miscible in water, alcohol, ether, acetone, and ethylene glycol. DEG is a widely used solvent. It can be a contaminant in consumer products; this has resulted in numerous epidemics of poisoning since the early 20th century. DEG is produced by the partial hydrolysis of ethylene oxide.
