“…A c c e p t e d M a n u s c r i p t 8 show better dispersion, in good agreement with the literature [51][52][53]. It has been confirmed that GO or ERGO, which could be physico-chemically and structurally regarded as unconventional polymeric surfactant structures, may act as capping agent or stabilizer to disperse and hamper the growth of the NPs [21].…”

“…The electrochemical detection of DA and UA has been investigated on graphene or GO-based in some papers [47][48][49][50][51][52][53], but the necessity of continuing further studies with an intention to attain lower detection limits exists now [54][55][56][57][58][59][60]. And one-step electrodeposition of Pt-Au bimetallic nano-clusters loaded onto GO for simultaneous DA and UA has not been reported.…”

“…Graphene has already been used in various fields, especially in catalysis, and sensors. [16][17][18][19][20][21][22][23] The graphene sheets can be readily synthesized by reducing oxygen functional groups such as hydroxyl, epoxide, and carboxyl groups (on planes and edges) present on the surface of graphene oxide (GO). 24 Doping is one of the simple and efficient way to increase the catalytic activity of graphene catalysts because they not only exhibit excellent electrocatalytic activity but also possess other advantages including low cost, better stability, and environment-friendly.…”

Both nitrogen and sulfur dual doped graphene supported Fe 2 O 3 (NSG-Fe 2 O 3 ) have been prepared by hydrothermal methods and subsequently utilized for the electrochemical determination of dopamine (DA) in presence of ascorbic acid (AA). The NSG-Fe 2 O 3 has been characterized via transmission electron microscopy (TEM) and X-ray photoelectron spectroscopic (XPS). The electrochemical detection of DA was measured through the cyclic voltammetry, differential pulse voltammetry, and amperometric techniques in a 0.1 M phosphate buffer solution (PBS) at pH 7.4. Interferences have been investigated in presence of AA, glucose, serotonin, N 2 H 4 , and uric acid. The NSG-Fe 2 O 3 has shown good analytical performance for DA with comparatively better sensitivity (29.1 μA mM −1 ), long linear detection range (0.3-210 μM) and detection limit (0.035 μM) (S/N = 3). The catalytic rate constant for DA detection has been calculated as 9.6 × 10 4 M −1 s −1 with a good diffusion coefficient of 3.5 × 10 −4 cm 2 s −1 . The electrooxidation of DA may enhances by fast proton acceptance and/or electron donation due to higher electron density for excess loan pair electron that provided from N and S dual-doped graphene sheets. 3,4-dihydroxyphenyl ethylamine (dopamine, DA) plays a significant role as a neurotransmitter in the function of the central nervous, renal and hormonal system. Low levels or abnormalities in DA concentration may lead to several neurological diseases, such as schizophrenia, Parkinson's disease, attention deficit hyperactivity disorder, restless legs syndrome and drug addiction.1-4 It is, however, several analytical techniques have been developed for DA detection, including high performance liquid chromatography, 5 chemiluminescence 6 and gas chromatography-mass spectrometry, 7 but each technique has several disadvantages. On the other hand, electrochemical sensing is preferred alternative method because of simple operation, fast response, time savings, low-cost, high-sensitivity and excellent selectivity. [8][9][10][11] Nevertheless, the electrochemical determination of DA is generally hindered by high concentration ascorbic acid (AA) which is another electroactive species that plays an important role in human metabolism and interfering species for DA sensing. Through the electrochemical method, it is difficult to sense DA selectively in the presence of high concentration AA, because these two species are responding nearly the same oxidation potential on the bare electrode, resulting in poor selectivity and sensitivity of DA detection. 12Graphene sheets are highly conductive and have 2D flat lattices consisting of a monolayer of sp 2 -hybridized carbon atoms. Due to high electrical conductivity and electron mobility, large surface area, long-term stability and unique mechanical flexibility, 13-15 graphene has attracted a great deal of research interest. Graphene has already been used in various fields, especially in catalysis, and sensors. [16][17][18][19][20][21][22][23] The graphene sheets can be readily synthesiz...
