LAOAG CITY, Ilocos Norte — A DNA-based nanobiosensor detection system for food-borne and water-borne pathogens that could help possibly identified the presence of the African Swine Fever (ASF) virus in just a span of several hours.

The nanobiosensor technology was exhibited at the Regional Science and Technology Week at the Centennial Arena in this city starting yesterday until Friday.

Science and Technology Sec. Fortunato Dela Pena said in a press conference yesterday that he is encouraging the developer of the technology to pursue its development for the early detection of the ASF virus.

The technology was developed by University of the Philippines- Los Banos (UPLB) in collaboration with the Michigan State University and Philippine Council for Industry, Energy and Emerging Technology Research and Development (PCIEERD) of the Department of Science and Technology.

Dela Pena said that blood samples for laboratory confirmation for the ASF have to be brought to the United Kingdom for the confirmation of the ASF virus while the exhibitor of the nonobiosensor for pathogens said these can be done faster within the confines of the animal pens and the results can be had within five to six hours.

The exhibitor said that a little modification on the technology is needed for it to be used in testing for the presence of the ASF virus.

The exhibitor said the technology was developed by Francisco Elegado of UPLB and Russel Pili o PCIEERD that offers for a quick and easy way to sense or detect the presence of harmful bacteria, such as E. coli, E. coli 0157:H7 and Salmonella enterica in the food, water or in animal feeds.

The process involves for the DNA extraction from pathogen target via 30-second extraction protocol.

It will then undergo dual hybridization (attachment of the designed detector and capture probes to the extracted DNA).

Finally undergoes electrochemical detection (the measurement of the amount of target DNA present in the sample). (RONDA Balita Online News)
