The continually expanding toolkit from Mohit Verma’s laboratory at Purdue University now includes a portable paper-based biosensor for identifying genetically modified corn and soybean. The genetically modified crop biosensor, based on a method called loop-mediated isothermal amplification – LAMP – offers a fast and less expensive alternative to the point-of-need molecular tools already on the market.

Purdue University research scientist Bilal Ahmed examines a microfluidic paper-based biosensor cartridge under light to display the visible results of an assay for genetically modified crop traits.
A Purdue University research team led by Mohit Verma has developed a paper-based test to rapidly detect genetically modified crop traits directly from leaves. Bilal Ahmed, a research scientist in agricultural and biological engineering, adds diluted leaf extract from GM corn to a microfluidic paper-based analytical device biosensor cartridge for trait detection.
