Project to use low-cost biosensors to detect presence of pathogens

The project, called BioSPACE, which stands for Biosensing Surveillance of Pathogens in Aquaculture and Coastal Environments, is designed to continuously monitor the water in real-time and send an alert to take immediate steps to help prevent the spread of diseases.

BioSPACE aims to give farmers, environmental agencies and water-reliant industries a rapid, portable, easy-to-use and monitoring and early warning system that is low in cost, yet sensitive.

“Existing technologies for detecting waterborne pathogens, such as PCR, are too slow and costly for large-scale deployment,” Luo said.“Delayed test results can lead to the spread of pathogens, which can progress to coastal contamination and extensive aquaculture losses.”

Although Luo's research team has primarily concentrated on biosensor technology for public health uses, such as monitoring for the COVID-19 virus in municipal wastewater and sewage, this project marks its first effort to explore the technology in a complex setting like seawater.

 

 

The team's initial targets are bacterial and viral pathogens such as Vibrio that occur in shrimp aquaculture and coastal waters and can lead to diseases in farm-raised aquatic animals and humans. “We will assess how well our biosensors will perform over time and how accurate they are in detecting specific aquatic pathogens, said Luo.
