Abstract
A microfluidic valve can include a substrate having a microfluidic channel formed in the substrate. A sealing layer can be over the microfluidic channel. A flexible blister layer can be over the sealing layer. The flexible blister layer can include a blister formed as a distended portion with a blister volume between the flexible blister layer and the sealing layer. The microfluidic valve can be actuatable by puncturing the sealing layer by pressing on the blister. Actuating the microfluidic valve can either allow fluid to flow through the microfluidic channel or block fluid from flowing through the microfluidic channel.
