Purdue University researchers have developed a biosensor technology aimed at revolutionizing food safety in agriculture. This innovation stems from a collaboration with the Center for Produce Safety, which sought to create a rapid, user-friendly risk assessment tool for growers of fresh produce, including leafy greens.

"Current tests used in the field are slow, lab-based, and require trained personnel," explains Mohit Verma, associate professor in the Department of Agricultural and Biological Engineering and one of the researchers on the project. "Our goal was to provide growers with a quick and easy-to-use tool that offers rapid, reliable results."

The solution lies in biosensors, which detect biological molecules and provide easily readable outputs. The technology employs Loop-Mediated Isothermal Amplification (LAMP), a method similar to PCR but simpler as it operates at a single temperature. This makes it feasible for field use, allowing tests to be conducted in basic settings like water baths.
