Glucose sensing based on interdigitated array microelectrode.
A micro glucose sensor consisting of an interdigitated array gold microelectrode was developed. The interdigitated array structure, which has 10 microns band width and 10 microns band gap, was fabricated in a small region (2.5 x 5 mm2) on a quartz substrate. Glucose oxidase was chemically fixed onto the electrode surface through self-assembled monolayer of 11-mercaptoundecanoic acid; ferrocenea...
متن کاملImpedance Immunsensor Based on Interdigitated Array Microelectrode and its Experiment Parameter Optimization
This article accounts for a novel impedance immunosensor based on the specificity reaction of the antigen-antibody and the sensitivity of the interdigitated array microelectrode (IDAM) for the determination of chlorpyrifos residues. The basic knowledge of immunoassay was in relation to its IDAM electrode surface modification, antibody immobilization, bovine serum albumin (BSA) blocking and samp...
متن کاملLarge-area interdigitated array microelectrodes for electrochemical sensing
Advanced photolithography developed for the semiconductor industry has been used to fabricate interdigitated microelectrode arrays that pass steady-state limiting currents of up to 230 nArmM analyte — 2.5 times more than the most sensitive interdigitated array built to date, and exhibit response times of ;5 ms. This performance results from the small interelectrode gap and the large active area...
متن کاملElectrochemical Measurements with Interdigitated Array Microelectrodes
ing into widespread use for the trace determination of easily oxidizable and reducible organic and inorganic compounds, because it provides a rather easy procedure for direct and selective detection. Recently, microelectrodes have been receiving attention in this field (1,2). They offer higher sensitivity than macroelectrodes of conventional size, because an electroactive molecule can approach ...
متن کامل3D nanogap interdigitated electrode array biosensors.
Three-dimensional interdigitated electrodes (IDEs) have been investigated as sensing elements for biosensors. Electric field and current density were simulated in the vicinity of these electrodes as a function of the electrode width, gap, and height to determine the optimum geometry. Both the height and the gap between the electrodes were found to have significant effect on the magnitude and di...
