New dual electrochemical detector for microbore liquid chromatography determination of dopamine and serotonin in rat striatum dialysates

Simultaneous measurement of dopamine, serotonin, their metabolites and tryptophan in mouse brain homogenates by high-performance liquid chromatography with dual coulometric detection

“…Fluorescence (Lee Chin, 1992) and amperometric detection (Seegal et al, 1986;Herregodts and Michotte, 1987;Shibata and Onodera, 1988;Martin and Aldegunde, 1989;Leung and Tsao, 1992) are also commonly used. More recently, dual amperometric (Cheng et al, 1993(Cheng et al, , 1996 and fluorimetric and oxidative amperometric detection in series have been used (Lee Chin, 1992). To our knowledge, only one method has been described using coulometric detection (Saito et al, 1992).…”

Differential alteration of catecholamine release during chemical hypoxia is correlated with cell toxicity and is blocked by protein kinase C inhibitors in PC12 cells

“…Catecholamine measurements have been described previously [Cheng et al, 1996[Cheng et al, , 2000. Dialysis probes were perfused with Ringer's solution at 1 l/min using a CMA/100 microinfusion pump.…”

A disposable amperometric sensor for rapid detection of serotonin in the blood and brain of the depressed mice based on Nafion membrane-coated colloidal gold screen-printed electrode

“…Thus, fast detection of 5-HT in the blood is significant to the diagnosis, illness monitoring, prognosis and outcome of the depressed patients. Various approaches like fluorometry, HPLC-ECD, coulometry, capillary electrophoresis, TLC, voltammetry, mass and ELISA have been used to determine the concentration of 5-HT [3][4][5][6][7][8][9][10][11][12][13][14][15][16]. Although these conventional methods are the best choice for 5-HT detection in real samples, they are cumbersome and time-consuming, which makes them unsuitable for rapid detection, especially inconvenient for everyday test.…”
