Microdisc Electrode Arrays (MDEAs)

MDEAs are single electrodes wherein the contact between the conductor and the electroactive material under test is made through a series of tiny microdiscs arranged in a hexagonal close packed array; compared to the traditional single surface contact. Microdiscs of 50, 100, and 250 microns are microfabricated from 100 nm magnetron sputter-deposited Gold (Au), 100 nm e-gun vapor-deposited Platinum (Pt), or 100 nm Indium Tin Oxide (ITO) on an electronics grade borosilicate glass substrate. A 500nm thin insulating silicon nitride layer is applied over the conductor and that insulator is microlithographically windowed using reactive ion etching to reveal an array of microdisc-windows as awell as a single bonding pad to the conductor beneath. Great for transient electrochemistry, immobilized enzymes, electroactive polymers, polyelectrolyte layers and carbon nanotubes. More->

Microfabricated Chips Enable Advanced Biosensor and Biochip Research

ABTECH's line of microlithographically fabricated interdigitated microsensor electrodes, microband electrodes, and micodisc electrode arrays are well suited to the development of impedimetric, amperometric, and voltametric biosensors. Look for new E'Cell-on-a-Chip products in the Spring of 2005. More->
