“…However, electrochemistry scientists have demonstrated many acceptable methodologies to improve the performance of the bare electrode through modification of the working electrode [11][12][13]. There are so many different materials used in the literature to modify the working electrode, such as nanoparticles/composites [14], multiwall carbon nanotubes [15], organic compounds [16], ionic liquids [17] and surfactants [18].…”

To develop an electrochemical sensor for electroactive molecules, the choice and prediction of redox reactive sites of the modifier play a critical role in establishing the sensing mediating mechanism. Therefore, to understand the mediating mechanism of the modifier, we used advanced density functional theory (DFT)-based quantum chemical modeling. A carbon paste electrode (CPE) was modified with electropolymerization of brilliant blue, later employed for the detection of paracetamol (PA) and folic acid (FA). PA is an analgesic, anti-inflammatory and antipyretic prescription commonly used in medical fields, and overdose or prolonged use may harm the liver and kidney. The deficiency of FA associated with neural tube defects (NTDs) and therefore the quantification of FA are very essential to prevent the problems associated with congenital deformities of the spinal column, skull and brain of the fetus in pregnant women. Hence, an electrochemical sensor based on a polymerized brilliant blue-modified carbon paste working electrode (BRB/CPE) was fabricated for the quantification of PA and FA in physiological pH. The real analytical applicability of the proposed sensor was judged by employing it in analysis of a pharmaceutical sample, and good recovery results were obtained. The potential excipients do not have a significant contribution to the electro-oxidation of PA at BRB/CPE, which makes it a promising electrochemical sensing platform. The real analytical applicability of the proposed method is valid for pharmaceutical analysis in the presence of possible excipients. The prediction of redox reactive sites of the modifier by advanced quantum chemical modeling-based DFT may lay a new foundation for researchers to establish the modifier–analyte interaction mechanisms.

“…After completing research on electrodes RE-1 and RE-2 we have decided to check whether the lack of ionic liquid in graphite paste results in deterioration of electrodes potential stability. Literature review showed that there are numerous papers where graphite paste in electrodes consists of graphite powder and a binder, usually a plasticizer [42,43] or mineral/paraffin oil [44][45][46]. Therefore, RE-3 electrodes with graphite paste containing graphite powder and plasticizer (o-NPOE) we prepared, with membrane containing polyurethane, o-NPOE and ionic liquid.…”

Carbon paste electrodes (CPEs) are a type of electrochemical sensor that have been widely used for sensing and monitoring various analytes. Recently, there has been a growing interest in incorporating nanomaterials into CPEs to improve their performance and sensitivity.Here are some recent trends and applications of modified CPEs based on nanomaterials, which have been shown to have enhanced sensitivity and selectivity for the detection of various analytes such as those in food and drug samples. The high surface area and electrical conductivity of CPEs make them ideal for use in electrochemical sensing applications. Nanomaterial-based CPEs have also been widely studied for their high sensitivity and selectivity in sensing various analytes. Nanomaterials such as Multi-Walled Carbon Nanotube (MWCNT), Single-Walled carbon Nanotube (SWNCT), Graphene, or other naomaterial have excellent electrical conductivity, large surface area, and high mechanical strength, making it an attractive nanomaterial for use in CPEs. A CPEs-based nanomaterial has been used in electrochemical detection, demonstrating improved sensitivity compared to traditional CPEs. In general, the incorporation of nanomaterials into CPEs has opened up new opportunities for the development of highly sensitive and selective electrochemical sensors for a wide range of applications including environmental monitoring, drug diagnosis, and food safety.
