This disclosure provides systems, methods, and devices for processing samples on a microfluidic device. One method includes moving a sample from an upstream channel of a microfluidic device into a DNA manipulation module located downstream of the upstream channel. The DNA manipulation module includes a DNA manipulation zone configured to perform amplification of the sample, a first valve disposed upstream of the DNA manipulation zone, and a second valve disposed downstream of the DNA manipulation zone. The method also includes receiving the sample in the DNA manipulation zone; closing the first valve and the second valve such that as and liquid are prevented from flowing into or out of the DNA manipulation zone; and thermal cycling the sample in the DNA manipulation zone.
