Patent ID: 8394339

Claim:
A lab-on-a-chip (LOC) device comprising: a supporting substrate; a sample inlet for receiving a fluid sample; an incubation section in fluid communication with the sample inlet, the incubation section having at least one heater; a reagent reservoir for holding a reagent used in the incubator; a surface tension valve having an aperture configured to pin a meniscus of the reagent, said meniscus in fluid communication with the inlet such that the meniscus retains the reagent in the reagent reservoir until contact with the fluid sample removes the meniscus and the reagent flows out of the reagent reservoir; and, CMOS circuitry between the supporting substrate and the incubation section; wherein, the CMOS circuitry is connected to the at least one heater for maintaining the fluid sample at an incubation temperature for an incubation period.
