Chronoampermetric detection of enzymatic glucose sensor based on doped polyindole/MWCNT composites modified onto screen-printed carbon electrode as portable sensing device for diabetes

“…These materials can increase the surface for the immobilization of enzyme, electrocatalytic activity, and electron transfer ability. [23][24][25] The glucose sensors fabricated from metals and metal oxides, provide the high electron transfer capability, large surface area, and high electrocatalytic activity. However, these properties are ideally possible when they are of nanosized.…”

On the role of graphene oxide in bifunctional Ni/MOF/rGO composites in electrochemical nitrate detection and oxygen evolution reaction

“…12,14,15,[34][35][36][37][38][39][40][41][42][43][44][45][46][47][48][49][50][51][52] Numerous nanocomposites with a wide range of compositions are created and used as possible sensors for detecting different chemical agents, such as dopamine and bisphenol A, among others. 53,54 Metal-organic frameworks (MOFs) are anticipated to be crucial in electrochemical sensing applications. [54][55][56] Among the many porous materials, MOFs and MOF-derived materials can stand out and be excellent choices because (1) they have various pore sizes and shapes to meet the unique requirements of metal nanoparticles; (2) they have high porosity and specific surface areas to carry metal nanoparticles; and (3) understanding catalysis requires precisely defining the MOF structure and making sure that the pore structure is easily tailored to make sure that the surrounding environment is not affected.…”

[54][55][56][57][58][59][60][61][62][63][64][65] The oxygen evolution reaction or OER for short, is a limiting reaction in chemical processes that produce molecular oxygen: oxidation of water during oxygenic photosynthesis, electrolysis of water into oxygen and hydrogen, and electrocatalytic oxygen evolution from oxides and oxoacids. [66][67][68][69][70] The advancement of numerous distinct renewable energy technologies depends on the creation of improved catalysts for the OER.…”

Direct and Sensitive Electrochemical Detection of Bisphenol A in Complex Environmental Samples Using a Simple and Convenient Nanochannel-Modified Electrode

“…(Liu et al, 2020;Sabbaghan et al, 2021;Xuan et al, 2021;Ghalkhani and Sohouli, 2022) The electroactive phenolic hydroxyl groups in BPA enable its detection by electrochemical sensing. To improve the detection sensitivity, researchers have used a variety of materials to modify the working electrode, including metal or metal oxide nanoparticles (Ashraf et al, 2020;Wang et al, 2020b;Yang et al, 2022), carbon materials (Yasri et al, 2015;Alam and Deen, 2020;Zhu et al, 2020;Ponnada et al, 2022;Wang et al, 2022), ionic liquids (Wang et al, 2018;Wang et al, 2021b), molecularly imprinted polymers (Beduk et al, 2020;Zhang et al, 2021), metals and covalent organic frameworks (Zhang et al, 2018;Pang et al, 2020), and aptamers (Hadi et al, 2016;Jun et al, 2020). However, these modified electrodes often require expensive reagents/ materials or complicated synthesis processes.…”
