Dolomite has been involved in a number of projects integrating electrode features in microfluidic devices, combining the advantages of both microfluidics and electrochemistry.
Embedded between two glass layers or placed on top of a microfluidic chip, electrodes enable on- chip functionality, including electrical impedance spectrometry, electrophoresis, amperometric detection and electrical heating.
Dolomite's high-voltage microfluidic thermal bonding process allows the creation of complex and leak-free microfluidic structures with electrodes from as small as 2um.
An additional layer of PECVD oxide or PECVD nitride can be applied to the electrodes for insulation.
Available in a wide range of materials, including platinum, copper, titanium and gold, the electrodes can cover up to 50 per cent of the microfluidic chip when bonded.
