Zn2+ induced self-assembled fabrication of marigold-like ZnO microflower@Ni(OH)2 three-dimensional nanosheets for nonenzymatic glucose sensing

Wearable non-invasive glucose sensors based on metallic nanomaterials

“…The typical catalyst materials applied in the wearable non-invasive glucose sensors are mainly enzyme-based materials like glucose oxidase (GOx) and glucose dehydrogenase (GDH) ([ [18] , [19] , [20] ]), polymer-based materials like 3-aminophenylboronic acid (3-APBA) ([ 21 ]), metal-based materials including Cu 2 O, NiCeOx, ZnO@Ni (OH) 2 , etc. ([ [22] , [23] , [24] , [25] ]). The enzyme-based and polymer-based materials have not only poor conductivity but also relatively low sensitivity.…”

Comparison of Electrocatalytic Performance of CuCo2O4 Nanorods and Nanospheres Decorated with Co3S4 Nanosheets for Electrochemical Sensing of Hydrogen Peroxide and Glucose in Human Serum

“…In the early days, usually, enzymatic-based materials, as sensing elements, were used to modify the electrodes for sensitive and specific detections. However, the enzyme-based sensors generally have some drawbacks such as instability and complicated modification and immobilization procedures. , Therefore, as an alternative to enzymatic sensors, attention has been turned to nonenzymatic sensors based on noble metals and their alloys, transition metal oxides/sulfides/phosphides, carbon materials, and conductive polymers. − Transition metal oxides have great application potential as sensor materials due to advantages of abundance, low cost, diversity, excellent stability, and especially unique d-orbital characteristics, which enhance their electrocatalytic activity. According to the literature and “volcano” relation model, cobalt is one of the potential electrocatalysts, and cobalt-based nanomaterials with different compositions and morphologies are promising as sensing elements for various electroactive materials.…”

Novel Synthesis of Sensitive Cu-ZnO Nanorod–Based Sensor for Hydrogen Peroxide Sensing

“…It is, therefore, vital for both industrial and academic purposes to be able to quickly, easily, and reliably carry out determination of H 2 O 2 ( Arsalan et al, 2021a ). The detection of H 2 O 2 has been accomplished by a number of analytical techniques, including titrometers, spectrophotometers, fluorescence, phosphorescence, chromatographies, and electrochemical techniques ( Li et al, 2016 ; Waqas et al, 2022 ). The electrochemical technique is a superior alternative to the other methods because of its inherent sensitivity, wide detection range, rapid response, low cost, and good selectivity ( Lin et al, 2010 ; Aziz et al, 2022a ).…”
