Thongchai Kaewphinit received the MSc in Biomedical Science from Srinakharinwirot University (SWU), Thailand in 2007, and PhD in Molecular Biology from SWU in 2010. Recently, he is a Lecturer of Innovative Learning Center, SWU. Biosensor, nanotechnology, molecular biology and applied microbiology are his current research field. He has published more than 12 papers in refereed journals.

In the present methods for molecular detection include normal or nested polymerase chain reaction (PCR) followed by electrophoresis, real-time PCR assay. These techniques entail various disadvantages such as high cost, long assay time or use of toxic substances.
