“…However, in acid system, contaminants were hardly oxidized directly. Its degradation was mainly through the reaction with reactive groups of the solution-indirect oxidation [24]. Thus, alkaline and neutral systems are favorable for the degradation of ARB if the effects of electrolyte are omitted.…”

Graphite-lead dioxide electrodes doped with rare earth Cerium (Ce-PbO 2 /C electrodes) were prepared by electrodeposition. The scanning electron microscope results showed that the microstructure and crystal orientation of electrode surface were changed by Cerium doping. CeO 2 was detected from modified electrodes by X-ray diffraction analysis. The cyclic voltammetry spectra indicated that the oxidation peak potential of cerium-doped electrode was smaller than pure PbO 2 electrode. Effects of the novel electrode on acid red B degradation were evaluated systematically under different parameters, including applied voltage, initial pH, supporting electrolyte concentration, electrode spacing, and influent concentration. The results indicated that chemical oxygen demand, decolorization, and ammonia nitrogen removal rate of Ce-PbO 2 /C electrodes reached 90.17, 99.98, and 97.23 %, respectively, after 60-min electrolysis at initial 1000 mg L −1 acid red B concentration. The possible mechanism of acid red B degradation over Ce-PbO 2 /C electrodes was monitored by gas chromatography-mass spectrometer.

Neurotransmitters, acting as chemical messengers, play an important role in neurotransmission, which governs many functional aspects of nervous system activity. Electrochemical probes have proven a very useful technique to study neurotransmission, especially to quantify and qualify neurotransmitters. With the emerging interests in probing neurotransmission at the level of single cells, single vesicles, as well as single synapses, probes that enable detection of neurotransmitters at the nanometer scale become vitally important. Electrochemical nanoprobes have been successfully employed in nanometer spatial resolution imaging of single nanopores of Si membrane and single Au nanoparticles, providing both topographical and chemical information, thus holding great promise for nanometer spatial study of neurotransmission. Here we present the current state of electrochemical nanoprobes for chemical detection of neurotransmitters, focusing on two types of nanoelectrodes, i.e. carbon nanoelectrode and nano-ITIES pipet electrode.

Dysregulation of neurotransmitters (NTs) in the human body are related to diseases such as Parkinson's and Alzheimer's. The mechanisms of several neurological disorders, such as epilepsy, have been linked to NTs. Because the number of diagnosed cases is increasing, the diagnosis and treatment of such diseases are important. To detect biomolecules including NTs, microtechnology, micro and nanoelectronics have become popular in the form of the miniaturization of medical and clinical devices. They offer high-performance features in terms of sensitivity, as well as low-background noise. In this paper, we review various devices and circuit techniques used for monitoring NTs in vitro and in vivo and compare various methods described in recent publications.
