Biosensing Technology Research Unit integrates emerging technology platforms to develop novel biodiagnostics for the needs of Thailand. The technology platforms that have been established include recombinant protein technology, transcriptomics, phage-based binders, microarray, bead array, LAMP-based sensors and metabolomics.
- Biodiagnostics for agricultural and food applications aims to develop multiplex detection method for foodborne pathogens and plant pathogens by applying microarray technology in combination with target-specific antibodies. In addition, to answer the actual need of aquatic animal farming, various LAMP-based sensors are developed to provide a rapid, accurate and inexpensive test for diseases of several economically important aquatic animals such as shrimp and fish. Moreover, DNA microarray is employed for gene expression analysis of an organism using the black tiger shrimp as a model. Metabolomic technology is utilized to investigate potential metabolite markers for important traits in agricultural produces and food products.
- Biodiagnostics for healthcare and medicine employs transcriptomics and metabolomics to identify biomarkers associated with infectious diseases and aging-population diseases for diagnostic and drug development.
- Biodiagnostics for environment aims to develop analytical method to measure the activity of methanogens for biogas production in the wastewater treatment system.
