Nonenzymatic glucose sensor based on ITO electrode modified with gold nanoparticles by ion implantation

X-Ray Photoelectron Spectroscopic Characterization of Chemically Modified Electrodes Used as Chemical Sensors and Biosensors: A Review

“…Hu et al developed a nonenzymatic glucose sensor obtained by depositing gold nanoparticles on an indium tin oxide electrode (AuNP/ITO) via an ion implantation technique [66]. The CME was characterized by AFM, XPS and CV.…”

“…The first section includes papers in which XPS characterization was mainly focused at exploring C 1s and/or O 1s and/or N 1s regions . The second includes papers in which the spectroscopic regions of a specific element were explored [53][54][55][56][57][58][59][60][61][62][63][64][65][66][67][68][69][70]. In the last one, a more comprehensive analysis of the spectroscopic regions of multiple elements is involved .…”

Properties of an Indium Tin Oxide Electrode Modified by a Laser Nanostructured Thin Au Film for Biosensing

“…[48,49] This is con- firmed by the clear anodic signal located at about +0.2 V, which corresponds to continuous oxidation of gluconolactone -an intermediate form releasing one proton per glucose molecule. [50] It can be observed, that this second anodic peak is much higher than the first one. With an increase of the applied potential above +0.4 V, the gold oxide is generated on the electrode surface and the oxidation process leads to passivation of Au.…”

One pot synthesis of poly(5-hydroxyl-1,4-naphthoquinone) stabilized gold nanoparticles using the monomer as the reducing agent for nonenzymatic electrochemical detection of glucose

“…The state of the art nanotechnology has opened up new opportunities for materials scientists and electrochemists to acquire novel materials which could be employed to replace biocatalysts for electrooxidation of glucose. Particles of gold (Au) and platinum (Pt) metals and alloys have proven attractive for their ability to oxidize glucose with excellent activity [9,[11][12][13][14][15]. Interestingly, as the size of the particles goes down the hierarchy, macro to nano, the NPs exhibit more advantageous properties due to the increased percentage of the surface atoms and quantum size effects [16,17].…”
