Abstract

A label-free and high-sensitive sensing method of cancer DNA mutations using QCM(quartz crystal microbalance) is developed. The detection is based on the evaluation of the resonance frequecny. When probe DNA (pDNA) is introduced on quartz of sensor of QCM, the resonance frequency is shifted. When pDNA captures target mutant DNA through DNA hybridization, an additional resonance frequency shift occurs due to mass change in association with target DNA. The platform is able to sense EGFR, lung cancer mutant DNA with a limit of detection (LOD) of 1.0 nM.
