Provided is a flow control element for a microfluidic or nanofluidic device, comprising: a) a fluid source; and b) a flow restriction component; wherein the flow restriction component is situated downstream from the fluid source, and the flow restriction component has a hydrodynamic resistance at least 5 times higher than the hydrodynamic resistance of the device. Also provided is an apparatus comprising at least one flow control element and further comprising a microfluidic or nanofluidic device. Additionally provided is the use of the flow control element or apparatus. Further provided is a method of regulating the flow rate of a fluid entering or within a microfluidic or nanofluidic device, which method comprises altering the pressure applied to a fluid within a fluid source of a flow control element or apparatus as defined in any preceding claim. |
