The expense and difficulty of current biomarker detection methods is driving the design of microfluidic detection platforms. A ceramic microfluidic biosensor has been developed for conducting enzyme-linked immunosorbent assays (ELISA) using a novel polymerization amplified thermal detection (PATD) scheme. Prototype testing has yielded several results that support the viability of this device. It was seen that LTCC is an effective and durable substrate for the temperature sensor. Noise testing with our prototype revealed that our temperature sensors can detect changes as small as 0.01 K. Additional temperature testing showed that the thermistor behavior matches the expected thermistor beta equation. Finally, it was shown that polymerization reaction induction time is inversely proportional to glucose oxidase (GOx) initiator concentration. These preliminary results provide a foundation for future work developing the sensor into a protein detection device with cancer prognosis applications.
