“…The sensitive sensing system is also well-designed to further improve the analytical performance of NO sensor. There are two major channels for the design of NO sensitive surface, one is to employ redox mediator, such as macrocyclic metal complexes [31][32][33][34][35][36][37][38], watersoluble dyes [39][40][41][42][43] or metalloproteins [44][45][46][47][48][49], and the other is to introduce nanomaterials for the construction of the sensing interface.…”

Electrochemical sensing has been demonstrated to represent an efficient way to quantify nitric oxide (NO) in challenging physiological environments. A sensing interface based on nanomaterials opens up new opportunities and broader prospects for electrochemical NO sensors. This review (with 141 refs.) gives a general view of recent advances in the development of electrochemical sensors based on nanomaterials. It is subdivided into sections on (i) carbon derived nanomaterials (such as carbon nanotubes, graphenes, fullerenes), (ii) metal nanoparticles (including gold, platinum and other metallic nanoparticles); (iii) semiconductor metal oxide nanomaterials (including the oxides of titanium, aluminum, iron, and ruthenium); and finally (iv) nanocomposites (such as those formed from carbon nanomaterials with nanoparticles of gold, platinum, NiO or TiO 2 ). The various strategies are discussed, and the advances of using nanomaterials and the trends in NO sensor technology are outlooked in the final section.

“…The authors evaluated the effect of interfering species present in the extracellular brain fluid. The microsensor was selective towards NO (Santos 2013). Metallophtalocyanines are another group of metal-ligand complex displaying similar catalytic properties for NO oxidation/reduction to porphyrins (Bedioui and Griveau 2013).…”

Neurotransmitters are important biological molecules that are essential to many neurophysiological processes including memory, cognition, and behavioral states. The development of analytical methodologies to accurately detect neurotransmitters is of great importance in neurological and biological research. Specifically designed microelectrodes or microbiosensors have demonstrated potential for rapid, real-time measurements with high spatial resolution. Such devices can facilitate study of the role and mechanism of action of neurotransmitters and can find potential uses in biomedicine. This paper reviews the current status and recent advances in the development and application of electrochemical sensors for the detection of small-molecule neurotransmitters. Measurement challenges and opportunities of electroanalytical methods to advance study and understanding of neurotransmitters in various biological models and disease conditions are discussed.

“…Currently, a variety of NO determination methods have been proposed, such as photoluminescence, , surface-enhanced Raman spectroscopy (SERS), , and X-ray photoelectron spectroscopy . By contrast, electrochemical sensing has attracted much attention due to its simple operation, low cost, fast response, and excellent sensitivity. ,, Functional materials, such as metal and metal oxide nanoparticles, carbon nanomaterials, transition-metal complexes, and conducting polymers, have been extensively investigated and used in the field of electrochemical sensing of NO. Hu et al presented a sensor based on a cocoon-derived layered carbon fiber network fabricated with iron porphyrins of heme chloride, which achieves high sensitivity and selectivity in detecting NO molecules released from living cells cultured on its surface .…”

As a typical reactive nitrogen species, nitric oxide (NO) regulates various physiological processes in tissues. It is challenging to meet the requirements of low detection limit (a few nM) and wide detection range (larger than 1 μM) in detecting NO released from living cells. Herein, we prepare a nanoscale Ce-based metal–organic framework (CeMOF) biomimetic NO sensor, which obtains a high sensitivity (3.10 μA–1 μM–1 cm–2), a long detection range (6.00 nM to 312.67 μM), and a low detection limit (2.00 nM). Further, a CeMOF nanoparticle (NP) screen-printed electrode (SPE) chip is fabricated for cell adhesion and culture. By culturing cells on the surface, the CeMOF NPs/SPE achieves monitoring of NO molecules released from living HeLa and 293A cells. The Michaelis–Menten constant (K m) of the CeMOF biomimetic NO sensor is 1.3 nM, which indicates its excellent catalytic activity, which can be ascribed to the Ce coordination in CeMOF NPs to create high-density active catalytic centers for NO oxidation.
