Patent ID: 6969850

Claim:
A microfluidic device comprising a body and at least one nozzle extending outwardly therefrom, the body having at least one channel formed therein, each channel extending through the body from a first surface to a second surface thereof, wherein each channel has a reservoir section that is open at the first surface for receiving a sample, the at least one nozzle extending outwardly from the second surface, wherein each nozzle is in fluid communication with one channel such that each channel terminates in a nozzle opening that is formed as part of the nozzle, the body and at least one nozzle being formed by a process comprising the steps of: providing a mold which includes a negative impression of the channel and the at least one nozzle; injecting a polymeric material into the mold; curing the polymeric material to form the body with the at least one nozzle extending outwardly from the second surface with the at least one channel formed in the body; and removing the body from the mold.
