Piezoelectric Genosensor Based on PCR Amplification and Application to Detection of Human Papillomavirus Oncogene

This report presents a new concept of genosensor based on polymerase chain reaction (PCR) amplification with in-situ piezoelectric micro-mass measurement. Though there are increasing reports on DNA hybridization sensors based on electrochemical, optical and piezoelectric transducers with advantages such as simplicity and cost-effectiveness, the sensitivity of genosensors developed so far could not match with the PCR technique, which is well-known to be generated in abundance.
