There is provided a rough microfluidic channel for use, for example, in a lateral flow assay device. The rough microfluidic channel has a roughness greater than a similar channel that is smooth, as measured by a Reynolds number for flow under otherwise identical conditions, which is at least 50 percent greater than the Reynolds number for the smooth channel. Alternatively, the roughness may be greater than a similar channel that is smooth, as measured by the fill time which is at least 25 percent lower for said rough channel than said smooth channel.
