“…Shahid et al incorporated cobalt oxide nanocubes with rGO to form a nanocomposite for the modification of electrodes. [141] Thus modified electrode was used for the electrochemical detection of 5-HT in presence of interfering species such as DA, AA, and UA. The amperometric studies revealed a comparatively good detection in the range of 1-10 µM with LOD of 1.128 µM and sensitivity of 0.133 µA/μM.…”

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.

“…In recent years, electrochemical methods and particularly voltammetry, have attracted significant attention due to their benefits like sensitivity, simplicity, low cost, accuracy and selective specification of electroactive species [15][16][17][18][19][20][21][22][23][24][25][26][27][28]. In addition, the usage of electrochemical approaches towards detection of FA is generally promising because FA is the electrochemically active compound [29,30].…”

In the field of determination of vitamin B9 (folic acid, FA), we have described the development of a sensitive electrochemical sensor through promoting the screen-printed electrode (SPE) and taking the advantage of zinc ferrite magnetic nanoparticles (ZnFe2O4MNPs). Cyclic voltammetry (CV) experiments demonstrated the powerful activity of ZnFe2O4MNPs/SPE for electrooxidation of FA by showing the prominent oxidation peak at 600 mV vs. Ag/AgCl. By differential pulse voltammetry (DPV) measurements, a linear relation between current response and concentration of vitamin B9 was determined in the range of 1.0–100.0 µM, and detection limit is found to be 0.3 µM (S/N=3). Except high sensitivity, the developed sensor demonstrated high stability, reproducibility and repeatability, and was also successfully applied to specify FA in real samples of vitamin B9 tablets and human urine.

“…In fact, the Gr sheets are very good host materials to make nanocomposites for high performance electrochemical utilizations (Kim et al, 2009;Zhou et al, 2010;Vinodhkumar et al, 2018). Gr nanocomposites display acceptable benefits as one of the sensing platforms in electrochemical sensors (Luo et al, 2012;Thanh et al, 2016;Shahid et al, 2019). Combining the advantages of the unique features of Gr together with those ofCo 3 O 4 (the increased absorption capability, larger active site, and wide availability), the Gr/Co 3 O 4 nanocomposite provides stable and sensitive platforms for electroanalysis (Yavuz et al, 2013a,b;Feng et al, 2014).…”

A Screen-Printed Electrode Modified With Graphene/Co3O4 Nanocomposite for Electrochemical Detection of Tramadol

et al. 2020

In this paper, graphene (Gr)/Co3O4 nanocomposite was synthesized and utilized for the development of a novel electrochemical sensor to detect tramadol. Tramadol determination was examined by linear sweep voltammetry, differential pulse voltammetry, cyclic voltammetry, and chronoamperometry on Gr/Co3O4 nanocomposite-modified screen-printed electrode (Gr/Co3O4/SPE) in phosphate-buffered saline (PBS). Under the optimized condition, the detection limit of tramadol is 0.03 μM (S/N = 3) in the linear ranges of 0.1–500.0 μM. Furthermore, Gr/Co3O4/SPE was satisfactorily utilized to detect tramadol in tramadol tablet and urine specimens.
