				<BLOCKQUOTE class="style4">
				  <div align="justify"><B><FONT COLOR="#00af00">&Oslash;</FONT></B> Planar Metal Electrodes

				(PMEs) are highly uniform thin films of noble metals formed by

				magnetron sputter deposition or thermal evaporation onto planar

				insulating glass substrate plates. The conducting layer of gold

				or platinum (Pt or Au = 1,000 &Aacute;) is deposited following

				deposition of an adhesion promoting layer of titanium-tungsten

				(Ti/W = 100&Aacute;) that serves as the adhesion promoting layer.

				These layers are deposited onto a very smooth (60/40 scratch and

				dig finish), highly insulating, chemically resistant and

				non-leaching, electronics grade borosilicate glass substrate.

				Substrates such as silicon, with a thermally grown oxide or

				silicon nitride insulating layer, are also available.</div>

                <B>Cleaning:</B> Chips may be cleaned using any of the standard

				advice on cleaning is provided at ABTECH's &ldquo;<A HREF="files.html">Download

				<BLOCKQUOTE class="style4"><B><FONT COLOR="#00af00">&Oslash;</FONT></B>

			      <B>Coating:</B> Films or coatings may be applied to the PME or

				PITOE 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">&Oslash;</FONT></B>

			      <B>Electrical connection:</B> Electrical connections to the PMEs

				and PITOEs are best made using the STC 4 Test Clip.

				Alternatively, you may develop your own method of attachment of

				leadwires using a conductive epoxy (usually silver),

				low-temperature micro-soldering (indium) or simple alligator

				clip.</BLOCKQUOTE>

				and PITOE are tradenames 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 the simultaneous interrogation of the electrical,

				electrochemical, and optical properties of thin polymeric films

				and coatings, for applications in microelectrochemistry, and for
