Patent ID: 7060227

Claim:
A microfluidic combination comprising: a first substrate comprising a top surface with a first microchannel having a bottom formed thereon, wherein the first microchannel is disposed in between a first structure comprising a first pair of upstanding walls that protrude outwardly from the top surface, the bottom of the first microchannel being coplanar with the top surface, and wherein the first substrate and the first pair of upstanding walls are formed as an integral, unitary structure formed of the same material; a second substrate having an integral second structure that protrudes outwardly from the bottom surface thereof, wherein the second substrate and the second structure are formed of the same material; one of the two structures being adapted to be received in between the other structure so as to produce a frictional fit therebetween resulting in a sealed microchannel being defined between the two substrates.
