Microstructured polymer devices
First Claim
1. A method of manufacturing a device with a recessed electrode structure, the method comprising:
- providing a substrate with a microfluidic channel structure shaped to match the electrode structure;
applying a primer layer to the microfluidic channel structure, thereby forming a primed microfluidic channel structure;
spreading a conductive liquid to the primed microfluidic channel structure, the conductive liquid comprising a carrier medium, and the carrier medium comprising a solvent in which electrically conductive particles are dispersed;
distributing the conductive liquid throughout the microfluidic channel structure by capillary action; and
absorbing the solvent at least partially by the primer layer; and
evaporating remaining solvent from the carrier medium to allow the electrically conductive particles to form the recessed electrode structure.

Abstract
A method of manufacturing a device with a planar electrode structure, the method comprising: (a) forming a microfluidic channel on a substrate; (b) applying a primer layer to at least part of the microfluidic channel, (c) applying a conductive liquid to the microfluidic channel, the conductive liquid comprising electrically conductive particles dispersed in a carrier medium, the carrier medium including a solvent; (d) allowing the conductive liquid to flow throughout the microfluidic channel by capillary action to form the planar electrode structure; and (e) evaporating the solvent from the carrier medium, is described. Devices obtainable using the method and their applications are also described.
