Abstract:
1. A method for fabricating microfluidic valves comprising: forming at least one valving layer in a sheet of material wherein said sheet of material comprises sections separated by at least one perforated fold line forming a plurality of layers; forming at least one microchannel in said at least one valving layer wherein said at least one microchannel delivers pneumatic pressure to actuate at least one microfluidic valve formed in said sheet of material forming at least one fluid layer in said sheet of material; forming at least one microchannel in said at least one fluid layer wherein said at least one microchannel carries fluid; installing a flexible membrane on said sheet of material; folding said sheet of material said at least one perforated fold line separating said at least one valving layer and said at least one fluid layer around said flexible membrane; and adhering said folded material together around said flexible membrane wherein said plurality of layers comprise at least one of: double sided tape; elastomers; paper; adhesive layers; liners; foil; porous materials; glasses; and composites and wherein said material is adhered by at least one of: adhesive tapes; chemical adhesive; mechanical pressure; electrostatic attraction; melting; curable adhesive; epoxy; and urethane.
