Claim:
1. A microfluidic device, comprising: a substrate defining a microfluidic channel having a closed portion, the closed portion comprises: a liquid pathway defined by a wetting area, the wetting area of the liquid pathway being formed by at least a bottom wall and a lateral wall of the microfluidic channel for allowing liquid to advance and flow along the liquid pathway; and an anti-wetting area extending along and contiguously with the liquid pathway, 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, the vent communicating with the wetting area and the anti-wetting area and venting outside the microfluidic channel.
