The development of real-time PCR micro device with optical sensor for early detection of cancer.

We can detect cancer in the early stages by validating the expression of cancer specific nucleic acids in the blood. In this report, we have developed the micro device for performing real-time polymerase chain reaction (real-time PCR), one of the methods used for determining the quantity of nucleic acids, using a small volume of reagent. This all-in-one device can perform real-time PCR with the inclusion of heating control and the analyzing system with optical sensor.
