Dolomite has increased its offering with the ability to integrate metal electrodes into its range of glass and polymer microfluidic chips.
A 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 good chemical- and heat-resistant properties, platinum is most frequently used as an electrode material.
Normally between 50nm and 1um thick, a 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 2um.
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.
Dolomite also provides microfluidic devices and instruments in areas such as point-of-care systems, drug delivery and a range of biotech applications.
