Patent ID: 7914735

Claim:
A detection system comprising: a detection device comprising a region including electrodes spaced from one another to merge at least two small, separate drops placed on the electrodes and a thermometer configured and placed within the region to detect a potential signal generated by merger of the drops, a thermometer comprising a thermistor material with current being passed through it from an external source; and an anti-evaporation device, comprising a cap having at least one cavity that is positioned above and in contact with an upper surface of the detection device, forming a seal around the region, and at least substantially enclosing the region to inhibit mass transport from the drops out of the region such that evaporation from the region does not thermally dissipate the signal during a detection period of less than or equal to 4 seconds at 37° C. or less than or equal to 25 seconds at 5° C. and pogo pins inserted through the cap without breaking the seal around the at least one cavity for providing electrical connection to the detection device.
