Performance of polybithiophene-palladium particles modified electrode for non-enzymatic glucose detection

The COVID‐19 pandemic has continued to spread rapidly, and patients with diabetes are at risk of experiencing rapid progression and poor prognosis for appropriate treatment. Continuous glucose monitoring (CGM), which includes accurately tracking fluctuations in glucose levels without raising the risk of coronavirus exposure, becomes an important strategy for the self‐management of diabetes during this pandemic, efficiently contributing to the diabetes care and the fight against COVID‐19. Despite being less accurate than direct blood glucose monitoring, wearable noninvasive systems can encourage patient adherence by guaranteeing reliable results through high correlation between blood glucose levels and glucose concentrations in various other biofluids. This review highlights the trending technologies of glucose sensors during the ongoing COVID‐19 pandemic (2019–2020) that have been developed to make a significant contribution to effective management of diabetes and prevention of coronavirus spread, from off‐body systems to wearable on‐body CGM devices, including nanostructure and sensor performance in various biofluids. The advantages and disadvantages of various human biofluids for use in glucose sensors are also discussed. Furthermore, the challenges faced by wearable CGM sensors with respect to personalized healthcare during and after the pandemic are deliberated to emphasize the potential future directions of CGM devices for diabetes management.

“…42 Furthermore, complexes based on palladium metal were reported as catalysts for electrochemical sensors, and polybithiophene-palladium, and 3,4-ethylenedioxythiophene (EDOT)-substituted bis(2-pyridylimino)isoindolato-palladium complexes were used as a glucose sensor. 43,44 A Ni–Schiff base complex modified carbon paste electrode (MCPE) was prepared and used as anode catalysts for thiosulphate electrooxidation in alkaline medium. 45 It showed enhanced electrocatalytic performance due to the electro-generated Ni( iii ) mediator on the electrode surface with good stability and negligible poisoning effect.…”

“…Incorporating PdNPs in biosensors gave such high catalytic behaviour with good stability [23,24]. Electrochemical and some chemical methods have been used to incorporate PdNPs into a conducting polymer matrix [25][26][27]. Also, PdNPs could be dispersed in many other polymers [27,28].…”

In this work, palladium nanoparticles (PdNPs)/p1,5-DAN/ carbon paste electrode (CPE) and p1,5-DAN/CPE sensors have been developed for determination of hydrogen peroxide. Both sensors showed a highly sensitive and selective electrochemical behaviour, which were derived from a large specific area of poly 1,5 DAN and super excellent electroconductibility of PdNPs. PdNPs/p1,5-DAN/CPE exhibited excellent performance over p1,5-DAN/CPE. Thus, it was used for detecting hydrogen peroxide (H 2 O 2 ) with linear ranges of 0.1 to 250 µM and 0.2 to 300 µM as well as detection limits ( S/N = 3 ) of 1.0 and 5.0 nM for square wave voltammetry (SWV) and cyclic voltammetry (C.V) techniques, respectively. The modified CPE has good reproducibility, adequate catalytic activity, simple synthesis and stability of peak response during H 2 O 2 oxidation on long run that exceeds many probes. Both reproducibility and stability for H 2 O 2 detection are attributable to the PdNPs immobilized on the surface of p1,5-DAN/CPE. The modified CPE was used for determining H 2 O 2 in real specimens with good stability, sensitivity, and reproducibility.
