Abstract
A microfluidic device has a body, multiple channels, multiple reservoirs and multiple capillary valves. The reservoirs are formed on the body. Each channel is formed on the body and connects to a corresponding reservoir. The channels include a main channel and at least one branch channel. The main channel is formed on the top of the body and extends in a direction from the center to a circumference of the body. Each capillary valve is mounted on a corresponding channel and at a distance substantially close to the center of the body so differences between the burst frequencies of the capillary valves are increased. The microfluidic device has an excellent flow control on sequentially releasing fluid through distinct burst frequencies of microcapillary valves.
