Abstract
A microfluidic device and method for fabrication includes a microfluidic channel that has a closed portion, which comprises: a liquid pathway formed by a wetting area; and an anti-wetting area extending along and contiguously with the liquid pathway. The anti-wetting area is configured so as to provide a vent to evacuate gas along the anti-wetting area.
Claims17
A method of manufacturing a microfluidic device, comprising:
- forming a microfluidic channel in a substrate, the microfluidic channel having a closed portion;
- forming a liquid pathway using a wetting area in the closed portion, the wetting area of the liquid pathway having a bottom wall and a lateral wall as part of the microfluidic channel;
- and
- forming an anti-wetting area in the closed portion, the anti-wetting area extending along and contiguously with the liquid pathway, and the anti-wetting area extending along and contiguously with the lateral wall of the microfluidic channel and parallel to the liquid pathway, the anti-wetting area being configured to provide a vent to evacuate gas from the wetting area along the anti-wetting area to outside the microfluidic channel.
