Simultaneous determination of ascorbic acid, dopamine, uric acid, tryptophan, and nitrite on a novel carbon electrode

SU-8 based pyrolytic carbon for the electrochemical detection of dopamine

“…2 Carbon materials are widely used in the detection of DA and recently the detection of physiological concentration (o700 nM 3,4 ) of DA has been achieved by many approaches. [5][6][7][8][9][10][11][12][13][14] Even though the detection of DA using carbon based materials is widely examined, the roles of different oxygen based functional groups in this process are not known unambiguously. Here we show that the strong interaction between the hydroxyl groups on the surface and DA facilitates the redox reactions of DA.…”

Developing an electrochemical sensor for thein vivomeasurements of dopamine

“…In most cases, the sensor's exposure to the solution is short, and its surface is regularly cleaned and polished physically and chemically. Therefore, faced with reports of 2 weeks, 187 30 days, 188,189 60 days, 190 or 68 days 191 of sensor stability, it is necessary to pay attention to the determination environment.…”

Electrochemical Detection of Nitrite Using an Asymmetrically Substituted Cobalt Phthalocyanine Conjugated to Metal Tungstate Nanoparticles

“…These substances coexist with nitrite in the biological system and they all play vital roles in human and animal physiological processes. Various reports have been published emphasising the importance of the simultaneous detection of these substances [73][74][75][76]. Figure S7 shows the differential pulse voltammograms (DPV) of nitrite, ascorbic acid, dopamine, and uric acid on GCE/ CoPc/Bi 2 WO 6 .…”
