Claim 8:
9. A method of fabricating the microfluidic device system of claim 1, comprising:
fabricating the microfluidic device, comprising:
preparing a glass wafer for etching;
etching the glass wafer by introducing the glass wafer into an etching solution at a specific rate with a first end of the glass wafer being etched longer than subsequent portions of the glass wafer;
performing additional etching on the glass wafer by submerging the entire glass wafer, including a previously un-etched portion of the glass wafer, in an etching solution; and
measuring the etched profile of the glass wafer to thereby fabricate the microfluidic device; and

operatively coupling the microfluidic device to the visual sensor.
