Title: High-temperature, adhesive-based microvalves and uses thereof

Abstract

The present invention relates to adhesive-based microvalves, as well as assemblies and cartridges having such microvalves. In particular examples, substantially planar layers of adhesive materials are used to construct both normally-open and normally-closed microvalves for fluid control within microfluidic laminate cartridges. Such microvalves and cartridges can be useful for medical, chemical, and biological investigations.
