Abstract
The present invention is directed generally to devices and methods for controlling fluid flow in meso-scale fluidic components in a programmable manner. Specifically, the present invention is directed to an apparatus and method for placing two microfluidic components in fluid communication at an arbitrary position and time, both of which are externally defined. The inventive apparatus uses electromagnetic radiation to perforate a material layer having selected adsorptive properties. The perforation of the material layer allows the fluid communication between microfluidic components. Other aspects of this invention include an apparatus and method to perform volumetric quantitation of fluids, an apparatus to program arbitrary connections between a set of input capillaries and a set of output capillaries, and a method to transport fluid in centripetal device from a larger to a smaller radius. In addition, the present invention also is directed to a method to determine the radial and polar position of a pickup in the reference frame of a rotating device.
