Claim 10:
11. The microfluidic device of claim 10, wherein the microfluidic valve is a normally-open valve configured to allow a fluid to flow through the fluid flow microfluidic channel when the microfluidic valve is not actuated and block the fluid from flowing through the microfluidic channel when the microfluidic valve is actuated, wherein a non-newtonian plugging fluid is in the blister volume, wherein the blister is positioned to inject the non-newtonian plugging fluid into the fluid flow microfluidic channel when the blister is pressed and the sealing layer is punctured, and wherein the non-newtonian plugging fluid has a sufficient viscosity to block fluid from flowing through the fluid flow microfluidic channel.
