Electrochemical Detection of Bisphenol A Based on Gold Nanoparticles/Multi-Walled Carbon Nanotubes: Applications on Glassy Carbon and Screen Printed Electrodes

“…The highest peak current of BPA was observed at pH 7.0 ( Figure 4 b), which was chosen to maximize the electrode sensitivity and used for further analysis [ 46 ]. On the other hand, the oxidation potential shifted linearly towards negative potentials when the pH values were increased, and such phenomena suggest that protons are implicated in the electrochemical oxidation reaction ( Figure 4 c) [ 47 ]. The linear relationship obtained between pH and the potential value of the peak current and equal to E(V) = −0.057 pH + 0.98 (R 2 = 0.998), suggests that the number of electrons (see Scheme 1 ) was equivalent to the number of protons involved (2e − 2H + process) in the electrode reaction [ 42 , 48 ].…”

Development of a sustainable nanosensor using green Cu nanoparticles for simultaneous determination of antibiotics in drinking water

“…Nanotechnology refers to the science of designing and producing very small objects or structures at the nanoscale that are nanomaterials. As nanotechnology develops, nanomaterials are nding applications in health, 43 industries, 44 electronics, information technology, and environmental protection including water depollution. 45,46 The incorporation of nanomaterials into the design of electrochemical sensors has been explored over the last couple of decades to address some limitations in their performance, especially those encountered when dealing with real applications (e.g.…”
