Synthesis and electrochemical study of nanoporous palladium–cadmium networks for non-enzymatic glucose detection

Application of multivariate optimization to electrochemical determination of methyldopa drug in the presence of diclofenac at a nanostructured electrochemical sensor

“…Nanostructured materials have aroused dramatic interests for designing modified electrodes for electrochemical sensing due to their finite small size, high specific surface area, high porosity, and unique physical/chemical properties [29][30][31][32][33]. Among them, nanostructured transition metal hydroxides/oxides have excellent properties such as high surface area and enhanced chemical/electrochemical activities, as well [34,35].…”

A Highly Sensitive Nonenzymatic Glucose Sensor Based on Carbon Electrode Amplified with PdxCuy Catalyst

“…Figure 6(c) and (d) demonstrate the response currents of the interfering species, normalized with respect to that of 1 mM glucose, which is set as 100 % value. The figures reveal that the additions of 0.1 mM UA, AA and FR hardly affect the amperometric responses of glucose at ca −0.4 V and −0.65 V. The nafion in the constructed electrodes is seemingly helpful to provide a repelling effect toward the negatively charged AA, UA, causing the high selectivity to glucose [49]. The results reveal that lower potential is favorable for getting accurate sensitivity.…”

Constructing heterostructure on highly roughened caterpillar-like gold nanotubes with cuprous oxide grains for ultrasensitive and stable nonenzymatic glucose sensor

“…Therefore some recent efforts have been made for non-enzymatic sensors by immobilizing a variety of noble metal nanoparticles onto electrodes, such as platinum, gold, silver and their alloy (Ahmadalinezhad et al, 2013;Cao et al, 2013;Hsu and Wang, 2014;Li et al, 2014aLi et al, , 2014bLiu et al, 2013b;Niu et al, 2012;Wang et al, 2008;Xu et al, 2013Xu et al, , 2010 2014b; Yu et al, 2010). However, a relatively low selectively, resulting from the electrochemical sensitivity of noble metals toward the small organic molecules, was not favorable to their practical applications.…”
