“…Just as discussed above, a series of POMs based electrochemical sensors had been prepared and used to detect oxidants, but their electrocatalytic oxidation behaviors was seldom studied [16,29]. In this paper, ascorbic acid (AA) was chosen as model to investigate the electrocatalytic oxidation behavior of the PEI/PTA multilayer films modified electrode.…”

“…For example, Lee group had successfully fabricated the PDPA/PTA multilayer film, which possessed a remarkable electrocatalytic activity towards oxidation of ascorbic acid (AA) [15]. Ma et al had found that the P 2 W 16 V 2 -AuPd/PEI multilayer film can electrocatalyze oxidation of dopamine [16]. Cox and his co-workers had reported that the PMo 12 /PAMAM multilayer film exhibited efficient catalysis oxidation of arsenite [17] …”

“…Optical sensor (ECL, SERS and colorimetric) based on AuNPs and AuNPs-based nanocomposites provided a simple analytical Fig. 13 The schematic illustration of layer-by-layer self-assembly of P 2 W 16 V 2 -AuPd/PEI) 8 film [106] tool to detect DA with a quick response. The aggregation/ disaggregation of plasmonic AuNPs causes a color changing due to the SPR properties, giving it extra advantages as the optical probe in optical sensor.…”

This review (with 110 refs.) gives an overview on the progress that has been made in the past few years on the use of gold nanoparticles (AuNPs) for use in sensors and analytical tools for the determination of dopamine (DA). Both AuNPs and their composites with other organic and inorganic materials including noble metals are treated. Following an overview on the clinical significance of DA, we discuss the various analytical methods that are (a) electrochemiluminescence (ECL); (b) surface enhanced Raman scattering (SERS); (c) colorimetric probing and visual detection; and (d) the large class of electrochemical sensors. Subsections cover sensors based on plain AuNPs, bimetallic NPs, AuNP-metal@metal oxide nanocomposites, AuNP nanocomposites with organic polymers, AuNP nanocomposites with carbon nanotubes or with graphene, and finally sensors based on ternary materials containing AuNPs. The review ends with a conclusion on current challenges of sensors for DA and an outlook on future trends.

“…Secondly, VC plays a great role in the essential physiological processes of human bodies, such as cell division, gene expression, and activation of biological defense mechanisms (Arrigoni and Tullio 2002). Thirdly, VC has been used for the prevention and treatment of common cold, mental illness, infertility, cancer and so on (Du et al 2013;Zhou et al 2013;Cameron and Pauling 1978;Verrax and Calderon 2008;Takemura et al 2010). To attribute the success to the crucial role of VC in industrial applications and biochemistry, the development of a simple, rapid, and lowcost method for its determination has attracted great attention.…”

In pH 2.55 HCl solution, vitamin C (VC) could deoxidize [Fe(CN) 6 ] 3− producing [Fe(CN) 6 ] 4− , which reacted with Zr (IV) to form Zr[Fe(CN) 6 ] complex, then aggregated to produce {Zr[Fe(CN)6]} n nanoparticles by virtue of hydrophobic force and van der Waals force. The intensity of RRS at 340 nm is directly proportional to the concentration of VC in the range of 0.1-1.45 μg mL −1 , and the detection limit (3 s/k) is 0.128 ng mL −1 . In this work, the spectral characteristics of RRS, the optimum condition, the reaction mechanism of the reaction, and their influencing factors especially the effect of organic solvent have been studied. The sensitive, rapid, and simple method based on resonance Rayleigh scattering was successfully applied to determine trace amount VC in VC injection and tablet.
