“…Despite this, PANI exhibits strong ability in promoting electronic transmission. When compounded with PANI, the AA, DA and UA detection performance of a biosensor can greatly be improved . PEDOT is another kind of excellent conducting polymer which has been used in the simultaneous detection of AA, DA and UA .…”

In this study, poly(3,4-ethylenedioxythiophene) (PEDOT) and polyaniline (PANI) were electrodeposited via cyclic voltammetry (CV) on glass carbon electrode (GCE) layer by layer. The prepared electrode (GCE/PEDOT/PANI) was used for the simultaneous sensitive determination of ascorbic acid (AA), dopamine (DA) and uric acid (UA) at different oxidation potentials. The peak distances of AA and DA, DA and UA, AA and UA were 216 mV, 104 mV, 320 mV, respectively. For individual detection of AA, DA and UA, the linear ranges were 1 × 10 À 4 -1 × 10 À 2 M, 3 × 10 À 5 -1 × 10 À 3 M and 7 × 10 À 7 -1 × 10 À 4 M with detection limits of 2.42 × 10 À 5 M, 4.58 × 10 À 6 M and 2.38 × 10 À 7 M (S/N = 3), respectively. For simultaneous detection of AA, DA, and UA, the linear response ranges were 1 × 10 À 4 -1 × 10 À 3 M, 3 × 10 À 4 -1 × 10 À 2 M, and 3 × 10 À 6 -1 × 10 À 4 M with detection limits of 6.91 × 10 À 5 M, 3.66 × 10 À 5 M and 4.13 × 10 À 7 M (S/ N = 3), respectively. The GCE/PEDOT/PANI displayed good selectivity, reproducibility and storage stability, and was further applied to the detection of AA, DA, and UA in 5% normal human serum samples.

“…Besides this, the extremely low level of DA (<1 µM) compared to the concentration of AA (100-1,000 times higher than that of DA) needs to be considered (Ghanbari and Hajheidari, 2015;Edris et al, 2018). To address these issues, as well as the slow interfacial electron transfer, chemically modified electrodes (Anu Prathap et al, 2019) have been developed as sensing platforms based on conductive polymers (Xie et al, 2017;Li et al, 2019), MOFs (Fang et al, 2018), carbonaceous nanomaterials (Luo et al, 2016;Abellán-Llobregat et al, 2018), metal/metal oxide nanoparticles (Chen et al, 2018;Zhao et al, 2019a), and their composites (Grace et al, 2019;Lin et al, 2019;Zhao et al, 2019b).…”

A metal-organic gel (MOG) similar in constitution to MIL-100 (Fe) but containing a lower connectivity ligand (5-aminoisophthalate) was integrated with an isophthalate functionalized graphene (IG). The IG acted as a structure-directing templating agent, which also induced conductivity of the material. The MOG@IG was pyrolyzed at 600 • C to obtain MGH-600, a hybrid of Fe/Fe 3 C/FeO x enveloped by graphene. MGH-600 shows a hierarchical pore structure, with micropores of 1.1 nm and a mesopore distribution between 2 and 6 nm, and Brunauer-Emmett-Teller surface area amounts to 216 m 2 /g. Furthermore, the MGH-600 composite displays magnetic properties, with bulk saturation magnetization value of 130 emu/g at room temperature. The material coated on glassy carbon electrode can distinguish between molecules with the same oxidation potential, such as dopamine in presence of ascorbic acid and revealed a satisfactory limit of detection and limit of quantification (4.39 × 10 −7 and 1.33 × 10 −6 M, respectively) for the neurotransmitter dopamine.

“…For example, reduced graphene oxide combined with conjugated polymers and anionic polymer polysulfonic acid have been demonstrated as efficient electrochemical sensing of neurotransmitters [24]. MoS2 nanospheres and polyaniline loaded on reduced graphene oxide were used for simultaneous detection of these neurotransmitters [25]. The detection limit in the micro-molar range is generally obtained in these sensors and difference in oxidation potential are less than 200 mV.…”

In this study, an efficient and simple designed nanohybrid created for individual and simultaneous detection of ascorbic acid (AA), dopamine (DA) and uric acid (UA). This nanohybrid is a combination of chemical reduced graphene oxide (CRGO) and redox poly(para-phenylene) (Fc-ac-PP) modified in a lateral position with ferrrocenyl group CRGO/Fc-ac-PPP. The CRGO/Fc-ac-PPP nanohybrid demonstrated a synergistic effect resulting in a large conductivity, surface area and catalytic properties provided by the redox attached ferrocene. Moreover, this nanocomposite is able to detect individually as well as simultaneously AA, DA and UA in a co-existence system with defined and separated redox peaks oxidation. The linear response ranges for AA, DA and UA, when detected simultaneously, are 0.1–10000 μM, 0.0001–1000 μM and 0.1–10000 μM, respectively, and the detection limits (S/N = 3) are 0.046 μM, 0.2 nM and 0.013 μM, respectively. The proposed sensor shown satisfactory results when applied to real spiked urine samples for measuring the abnormal high or lowconcentration of AA, DA and UA in vivo.
