“…Developing HPOM-based materials in EC-sensing and biosensor applications has been acknowledged as one of the most promising potentials in POM chemistry, owing to the ideal reversible charge-transfer capability of HPOMs. − Studies have demonstrated that HPOMs can act as efficient electron donors or acceptors without structural change, which makes HPOMs valuable candidates for electron-exchange reactions. Because of their unique electronic structure, CNs have been favorably investigated to prepare POM–CN composites, in which a combination of POMs and CNs will contribute to a significantly enhanced electronic transport capability . Considering all of the above-mentioned factors, the composite of 1 with CFMCN has been proposed to modify glassy carbon electrodes (GCEDs) for further the EC detection of EDO.…”

Organic−inorganic hybrid metal−oxide clusters have been pursued for many years, benefiting from their abundant structures and prominent performances. Upon our exploration, a family of unusual mixed-heteroatom (Sb III , P III )-directing lanthanoid (Ln)-inserted h eteropolyoxotungstates ( Ln-HPOTs),functionalized by 1,2,3-propanetricarboxylic acid (H 3 ptca) was a c h i e v e d . T h e i n t r i g u i n g t r i m e r i c [ L n 4 ( H12− polyanion was established by two trivacant [B-α-Sb III W 9 O 33 ] 9− segments mounted on both sides and one rare [HP III W 4 O 18 ] 8− segment at the bottom, which are bridged via an organic−inorganic hybrid [W 4 Ln 4 (H 2 O) 12 O 10 (H 2 ptca) 2 ] 14+ central moiety. Such Ln-HPOTs involving dual-heteroatom-directing mixed building blocks, and even simultaneously modified by tricarboxylic ligands, are rather unseen in polyoxometalate chemistry. Moreover, the detection of 17β-estradiol through a 1-based electrochemical biosensor has been explored, demonstrating a low detection limit (7.08 × 10 −14 M) and considerable stability.

Carbon‐Nanotube‐Based Materials for Electrochemical Sensing of the Neurotransmitter Dopamine

2018

The development of new tools with outstanding performance for monitoring neurotransmitters is a challenging task in neuroscience. Electrochemical probes have attracted tremendous attention for the identification and quantification of neurotransmitters, owing to their demonstrated potential for quick response, real‐time measurements, elevated selectivity and sensitivity. In this Review, we have focused on the recent developments of carbon nanotube (CNT)‐based electrochemical sensors for dopamine detection. The use of CNTs is beneficial for this task, because of their high tensile strength, flexibility, good electrical conductivity, and low thermal expansion coefficient. Therefore, electrochemical sensing approaches with CNTs have opened the door for researchers working towards neurobiomedical applications.

The study of electrochemical behavior of bioactive molecules has become one of the most rapidly developing scientific fields. Biotechnology and biomedical engineering fields have a vested interest in constructing more precise and accurate voltammetric/amperometric biosensors. One rapidly growing area of biosensor design involves incorporation of carbon-based nanomaterials in working electrodes, such as one-dimensional carbon nanotubes, two-dimensional graphene, and graphene oxide. In this review article, we give a brief overview describing the voltammetric techniques and how these techniques are applied in biosensing, as well as the details surrounding important biosensing concepts of sensitivity and limits of detection. Building on these important concepts, we show how the sensitivity and limit of detection can be tuned by including carbon-based nanomaterials in the fabrication of biosensors. The sensing of biomolecules including glucose, dopamine, proteins, enzymes, uric acid, DNA, RNA, and H2O2 traditionally employs enzymes in detection; however, these enzymes denature easily, and as such, enzymeless methods are highly desired. Here we draw an important distinction between enzymeless and enzyme-containing carbon-nanomaterial-based biosensors. The review ends with an outlook of future concepts that can be employed in biosensor fabrication, as well as limitations of already proposed materials and how such sensing can be enhanced. As such, this review can act as a roadmap to guide researchers toward concepts that can be employed in the design of next generation biosensors, while also highlighting the current advancements in the field.
