“…Against this background, Jiao et al incorporated bimetallic Pd-Pt alloy (Pd@Pt) NPs with outstanding conductivity and chemical stability [170] as well as MWCNT with large surface area and excellent conductivity into a composite containing a POM for DA determination. [171] The CNT suspension was dispersed on a PEI coated ITO electrode which was subsequently immersed in a solution of a polyoxometalate (PMo 9 V 3 ) and Pd@Pt NPs to obtain an electrode tagged PMo 9 V 3 -Pd@Pt/CNT/ITO. In an AP experiment, LOD of 12.5 nM was obtained with this electrode.…”

Neurotransmitters (NTs) are chemical compounds that play an important physiological role in the functioning of central nervous, renal, hormonal, and cardiovascular systems. Their function is to regulate neural interactions by reducing the permeability of gap junctions between adjacent neurons of the same type. The abnormal level may lead to diseases, such as Parkinson's disease, Huntington's disease, Alzheimer's diseases, and other neurological diseases. The devastating health hazards associated with the abnormal presence of NTs in biological systems coupled with the demerits of most modern detection methods necessitates the continuous development of novel electrochemical sensors. Carbon nanotube (CNT)-based sensors, as a result of the large surface area, biocompatibility, and chemical stability supplied by CNTs, have proven to offer massive sensitivity and low limit of detection (LOD). Its significance in sensors applications toward the detection of different group of compounds cannot be overemphasized. There are several review articles on NTs and their determination using different chemically modified electrodes and sensor platform. However, this review highlights the significance of notable NTs and the progress made in the last decade in the design of CNT-based sensors for the detection of common NTs.

Polyoxometalates (POMs) have been used for spectrophotometric determinations of silicon and phosphorus under acidic conditions, referred to as the molybdenum yellow method and molybdenum blue method, respectively. Many POMs are redox active and exhibit fascinating but complicated voltammetric responses. These compounds can reversibly accommodate and release many electrons without exhibiting structural changes, implying that POMs can function as excellent mediators and can be applied to sensitive determination methods based on catalytic electrochemical reactions. In addition, some rare-earth-metal-incorporated POMs exhibit fluorescence, which enables sensitive determination by the enhancement and quenching of fluorescence intensities. In this review, various analytical applications of POMs are introduced, mainly focusing on papers published after 2000, except for the molybdenum yellow method and molybdenum blue method.

In this work, we demonstrate the incorporation of two-dimensional (2D) layered materials into a metal–organic framework (MOF) derived from one-dimensional (1D) cerium oxide (CeO2) for the electrochemical detection of dopamine. Ce-MOF was employed as a sacrificial template for preparing CeO2 with 2D materials by the pyrolysis process. The influence of the pyrolysis temperature was studied to achieve a better crystal structure of CeO2. Siloxene improved the dopamine sensing performance of CeO2 compared with graphitic carbon nitride (g-C3N4) due to the basal plane surface oxygen and hydroxyl groups of 2D siloxene. Under optimal conditions, the fabricated CeO2/siloxene electrode exhibited a detection limit of 0.292 μM, with a linear range from 0.292 μM to 7.8 μM. This work provides a novel scheme for designing the CeO2 material with siloxene for excellent dopamine sensors, which could be extended towards other biosensing applications.
