The idea is to develop a test for acute pancreatitis that can perform much faster than conventional tests while costing just a dollar to manufacture.
The sensor will consist of an LED light, milk protein, aluminum foil, gelatin, and a few other low cost materials. The sensor won't require any external energy source, and will able to detect acute pancreatitis within an hour with just drop of blood and, a bit later, a drop of lye. If the blood has high levels of trypsin (indicative of pancreatitis) that break through the gelatin layer, the lye will then eat through the foil layer, which will allow a circuit to form and the LED light to turn on.
