Microfabricated elastomeric valve and pump systems
First Claim
1. The method of using a microfluidic device, comprising:
- flowing a sample into a looped channel of the microfluidic device;
pumping the sample around the loop channel with a peristaltic action, wherein the peristaltic action comprises sequential activation of a series of individually addressable valves arranged along the looped channel.

Abstract
A method of fabricating an elastomeric structure, comprising: forming a first elastomeric layer on top of a first micromachined mold, the first micromachined mold having a first raised protrusion which forms a first recess extending along a bottom surface of the first elastomeric layer; forming a second elastomeric layer on top of a second micromachined mold, the second micromachined mold having a second raised protrusion which forms a second recess extending along a bottom surface of the second elastomeric layer; bonding the bottom surface of the second elastomeric layer onto a top surface of the first elastomeric layer such that a control channel forms in the second recess between the first and second elastomeric layers; and positioning the first elastomeric layer on top of a planar substrate such that a flow channel forms in the first recess between the first elastomeric layer and the planar substrate.
