Fabrication of enzymatic glucose biosensor based on palladium nanoparticles dispersed onto poly(3,4-ethylenedioxythiophene) nanofibers

Tuning the Initial Electronucleation Mechanism of Palladium on Glassy Carbon Electrode

“…Palladium is a well known catalyst for many reactions such as electrocatalytic oxidation of formaldehyde [37,38], hydrogenation of unsaturated hydrocarbons [39], oxidation of alcohols, and is routinely used in the automobile industry in catalytic converters to reduce the amounts of nitrogen oxides, carbon monoxide, and un-burned hydrocarbons [40]. Palladium is used in electronic industry, in view of its excellent resistance to corrosion and wear, good solderability and lower density, in the development of biosensors, and has been exploited as a component in an enzymatic glucose biosensor [41] as well as for detection of catecholamine [42] and DNA [43]. The initial electronucleation of a metal is dependent on parameters such as type and source of metal ion, concentration of metal ion, electrolyte and the substrate on which deposition takes place.…”

A silicon nanoparticle-based polymeric nano-composite material for glucose sensing

“…In this work, it was observed that PANI was able to oxidize AA as observed previously [17]. The total selec tivity of the nano-composite material for glucose against the inter fering agents can be provided, as previously shown, by either coating the sensing material with a thin layer of Nafion as an effec tive perm-selective membrane [18] or by dispersing Nafion solu tion in the sensing material [12]. In this work, the first approach was adopted.…”

Properties and Customization of Sensor Materials for Biomedical Applications

“…The sensor had a high sensitivity, 1.6 mA M À1 cm À2 , and was linear over a wide range of concentrations (0.5-30 mM). Besides, the sensor was able to detect glucose in diluted human serum samples, showing a small difference in relative percentage error (<3%) against values obtained with a standard reference method (281).…”

“…Nanofibrous PEDOT has been deposited on glassy carbon electrodes by a micellar-assisted soft template approach using [C 4 mim] [BF 4 ] and sodium dodecyl sulfate (281). The IL works as a co-surfactant and as a dopant for PEDOT.…”
