Abstract

We demonstrate an innovative method of PCR product identification that is based on thermal denaturation of PCR product-captured bead using integrated BioFET. Laborious purification and concentration of PCR product were easily carried by capturing the samples on the solid surface like microbeads. When temperature raised upto the denaturation point of PCR product, potential of BioFET is changed by mobile DNA in solution from PCR product-captured beads. By differentiating potential change with respect to temperature change, melting temperature can be determined. In this way, we successfully discriminated three kinds of PCR product using their different melting temperature and improved sensitivity of detection. We expect that proposed method can potentially be used for the identification of multiplex PCR products.
