Electrochemical Cell-on-a-Chip (ECC)

The Electrochemical Cell-on-a-Chip (ECC) is a microlithographically fabricated transducer array that is well suited for chemical and biosensor research and product development. It is available in two characteristic ABTECH microelectrode formats: i) the interdigitated microsensor electrode (IME) format of a pair of fingered working electrodes in circular aspect, and ii) the microdisc electrode array (MDEA) format of many conducting discs set beneath tiny openings in an insulating layer of silicon nitride.

Both the ECC IME and ECC MDEA are formed from patterned conductors (Gold, Platinum and ITO) on an insulating substrate (borosilicate glass) chip. The electrode buses are passivated with an insulating layer (0.5m) of silicon nitride (Si₃N₄). The ECC IMEs are 1.0 cm x 2.0 cm x 0.05 cm chips designed with a total of five (5) interdigitated fingers on each bus; ten fingers altogether. The interdigitated bands and spacings of ECC IME chips are available in 05, 10, 15, and 20 microns wide. The length of the fingers vary, depending on the width of the fingers and spaces. The ECC IME XX05 chips are available in gold (Au), platinum (Pt). and indium tin oxide (ITO). Each IME array is partnered with its own large area counter electrode and both IME arrays share a common reference electrode. The ECC IME XX05 chip therefore has a total of seven (7) electrodes. The ECC MDEAs are 0.2 cm x 0.4 cm x 0.05 cm chips designed with two (2) independently addressable microdisc array electrodes. Each microdisc array comprises discs that are 50 micron in diameter. A total of 37 such discs are formed through an insulating layer (0.5m) of silicon nitride (Si₃N₄); hence ECC MDEA 5037. The ECC MDEA 5037 is available in gold (Au), platinum (Pt), and indium tin oxide (ITO). Each microdisc array is partnered with its own large area counter electrode and both microdisc arrays share a common reference electrode. The ECC MDEA 5037 therefore has a total of five (5) electrodes.
