Claim 11:
12. The microfluidic device of claim 11, further comprising a second microfluidic valve that is a normally-closed microfluidic valve, wherein the second microfluidic valve comprises a second blister formed in the flexible blister layer, wherein the substrate further comprises a second microfluidic channel formed in the substrate, wherein the second microfluidic channel is in fluid communication with the second blister, wherein the sealing layer separates the second blister from fluid communication with the fluid flow microfluidic channel, and wherein puncturing the sealing layer places the second blister into fluid communication with the fluid flow microfluidic channel to allow fluid to flow between the fluid flow microfluidic channel and the second microfluidic channel through the second blister volume.
