Development Of BioFET Sensors For Real Time Monitoring Of Cyanotoxins

New field sensors will quickly scan for multiple algal toxins in water, food

A new sensor under development at The Ohio State University will detect harmful substances in water or food much more quickly than current methods.

When water safety is in doubt, public officials need quick answers about how much and what kind of substances are in the water. But in the case of harmful algal blooms, current methods for getting those answers are often a hassle, requiring samples to be taken back to a laboratory to be analyzed by specialized equipment—often meaning a delay of several days before results.
A research team led by Wu Lu, an electrical engineer in the College of Engineering, is developing a new sensor that can give immediate readings of which substances are present in water—right at the source. The sensor uses some biological components that link directly with algal toxins, so it is able to detect substances of concern even when there are very low amounts.

The End Result

A handheld device that can quickly and accurately measure multiple algal toxins of concern.
