“…Thus, the use of Na on on the modi ed GCE improves the conductance and the electron transfer rate of the resultant sensor. The similar characteristic of the sensor assembled using Na on has reported in several articles to detect toxic chemicals [47][48][49][50][51] The toxic chemicals in analytical grade such as benzaldehyde, 4-AP, 4-NPHyd, 2,4-DPDHCl, 3-CP, 3-MP, M-THydHCl, zimtaldehyde, 4-MP and 3-MPHydHCl were subjected to I-V investigation by assembled sensor based on ZnO/SnO2 NPs/GCE at rst illustrated in Fig. 3(a).…”

The 4-NPHyd (4-nitrophenylhydrazine) electrochemical sensor assembled using wet-chemically prepared ZnO/SnO2 nanoparticle (NPs) decorated a glassy carbon electrode (GCE) with conductive Nafion binder. The synthesized NPs characterized by XPS, ESEM, EDS, and XRD analysis. The calibration of the proposed sensor obtained from current versus concentration of 4-NPHyd found linear over a concentration (0.1nM~0.01mM) of 4-NPHyd, which denoted as the dynamic range (LDR) for detection of 4-NPHyd. The 4-NPHyd sensor sensitivity calculated using the LDR slope considering the active surface of GCE (0.0316 cm2), which is equal to be 7.6930 µAµM-1cm-2, an appreciable value. The detection limit (LOD) at signal/noise (S/N=3) estimated, and outstanding lower value at 94.63±4.73 pM perceived. The analytical parameters such as reproducibility, long-term performing ability and response time are found as appreciable. Finally, the projected sensor shows exceptional performances in the detection of 4-NPHyd in environmental samples.

“…[ 61 ] The enhanced electron transfer property and the desirable morphology tuning have resulted in the application of TMOs in electrochemical sensing. [ 62 ] This enhanced electrochemical property has driven TMOs as an important alternative for enzymatic detection, hence reducing the complexity and cost of the system. A schematic of the reaction pathways involved in the non‐enzymatic electrochemical sensing of neurotransmitters using TMOs modified glassy carbon electrode is provided in Figure 2.…”

Diagnosis of brain disorders is an extremely confronting task for the medical community and hence, the recognition and detection of pertinent biomarkers for neurological disorders is a crucial phase. Electrochemical techniques with transition metal oxide (TMOs) modified electrodes have emerged as a promising technique for the detection of neurotransmitters, which act as potent biomarkers. This review has tried to sum up the recent advancements made in the TMOs modified non-enzymatic electrochemical detection of important neurotransmitters in the last two decades. A comprehensive description of these neurotransmitters along with their biochemistry and impact on the human body is also provided. A short description of the future perspectives of the electrochemical detection of neurotransmitters is given highlighting the wearable sensors for the in vivo detection.
