Dolomite has increased its offering with the ability to integrate metal electrodes into its range of glass and polymer microfluidic chips. A wide variety of geometries can be created such as interdigitated electrodes, heaters and temperature sensors.

Applications include impedance detection and temperature control in microreactors and generation of electrical fields for dielectrophoresis. With its chemical- and heat-resistant properties, platinum is frequently used as an electrode material.

Normally between 50nm and 1µm thick, a wide range of metals can be deposited onto the microfluidic glass or polymer chips, including gold, copper, titanium and chrome. Metal feature size can be as small as 2 µm.

Furthermore, metal layers can also be deposited on the inside surface of the micro-channels. Applications requiring this type of deposition include optical flow cells where the metal layer acts as an optical light guide or mirror to reflect the light beam, and in catalytic reaction chips where the metal surface can be used to promote chemical reactions.

“With this metal electrode integration, we are able to offer our customers a different kind of microfluidic chip, expanding the range of applications for which microfluidics can be used”, said Mike Hawes, Dolomite’s Head of Marketing.

He continued, “With a truly extensive range of standard or customized microfluidic components, Dolomite has positioned itself as an industry leader equipped to meet the needs of any company seeking to reap the benefits of microfluidic technology”.

Along with Dolomite’s advanced capabilities in integrated metal electrodes for microfluidic chips, Dolomite also provide microfluidic devices and instruments in areas such as point of care systems, drug delivery and a wide range of biotech applications.
