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. </div>
</BLOCKQUOTE>
<div align="justify">
<BLOCKQUOTE class="style4"><B><FONT COLOR="#00af00">Ø</FONT></B>
In basic science and engineering research these devices are
designed for i) Electrical cell impedance and cell mobility
studies, ii) Simultaneous electrical (I/V), electrochemical (EA,
EIS) and optical (OD) characterization of polymeric thin films,
polyelectrolyte multilayers, protein films, and organic coatings,
iii) Electrochemical applications in microelectrochemistry, iv)
Electrochemical impedance spectroscopy, v) photoconductivity
measurements, and vi) Chemical and biological sensor research and
development.</BLOCKQUOTE>
<BLOCKQUOTE class="style4"><B><FONT COLOR="#00af00">Ø</FONT></B>
Both the ECC IME and ECC MDEA are formed from patterned
conductors (Gold, Platinum and ITO) on an insulating substrate
(borosilicate glass) chip. In both cases, the active electrode
areas are exposed through an insulating layer (0.5m)
of silicon nitride (Si<SUB>3</SUB>N<SUB>4</SUB>)
that electrically isolates and electrochemically passivates the
electrode buses but leaves the active electrode areas exposed for
the immobilization of your unique materials. </BLOCKQUOTE>
<BLOCKQUOTE class="style4"><B><FONT COLOR="#00af00">Ø
</FONT></B>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 therefore has a total of seven (7)
electrodes.</BLOCKQUOTE>
<BLOCKQUOTE class="style4"><B><FONT COLOR="#00af00">Ø
</FONT></B>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 (Si<SUB>3</SUB>N<SUB>4</SUB>);
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.</BLOCKQUOTE>
<BLOCKQUOTE class="style4"><B><FONT COLOR="#00af00">Ø
</FONT></B>In research and product development, these devices are
widely used for conductimetric, chemoresistive chemical and
biological sensors using electrically conducting
(electroconductive) polymers, for impedance sensors based on
Langmuir-Blodgett thin films, for studying environmental effects
on polymer thin films, and in modern micro-electrochemistry. </BLOCKQUOTE>

<B>Cleaning:</B> Chips may be cleaned using any of the standard
methods developed for microfabricated devices and chips. General
advice on cleaning is provided at ABTECH's “<A HREF="files.html">Download
Files</A>” web page.</div>

<BLOCKQUOTE class="style4"><B><FONT COLOR="#00af00">Ø</FONT></B>
<B>Coating:</B> Films or coatings may be applied to the ECC IME
or ECC MDEA devices by microcontact printing, dip coating, spin
casting, spray painting, air-brushing, brush painting, by the
Langmuir-Blodgett thin film deposition technique, by
electropolymerization, and by molecular self assembly.</BLOCKQUOTE>
<BLOCKQUOTE class="style4"><B><FONT COLOR="#00af00">Ø</FONT></B>
<B>Electrical connection:</B> Electrical connections to the ECC
IME XX05 devices is best made using the STC 7 Test Clip.
Alternatively, you may develop your own method of attachment of
leadwires using a conductive epoxy (usually silver) or
low-temperature micro-soldering.</BLOCKQUOTE>

Cell-on-a-Chip (ECC) is the tradename for a family of devices
developed by ABTECH Scientific, Inc. These devices are
microfabricated (using microelectronics fabrication techniques)
to form patterns of conductors deposited on an insulating
substrate chip. They are designed for cell motility studies, the
simultaneous interrogation of the electrical, electrochemical,
and optical properties of thin polymeric films and coatings, for
applications in microelectrochemistry, and for
electrical/electrochemical impedance spectroscopy.</BLOCKQUOTE>
