| abstract |
An M x N matrix microfluidic device for performing a matrix of reactions, the device (100) having a plurality of reaction cells (106) in communication with one of either a sample inlet (120) or a reagent t inlet (124) through a via formed within an elastomeric block of the device. Methods provided include a method for forming vias in parallel in an elastomeric layer of an elastomeric block of a microfluidic device, the method includes using patterned photoresist masks and etching reagents to etch away regions or portions of an elastomeric layer of the elastomeric block. |
