The traditional approach to identifying plant pathogens is to collect field samples, send them to a laboratory, and await the results. With Gene-Z, researchers said, they can take a swab of plant pathogens, transfer the sample to a kind of “lab-on-a-chip,” insert the chip into the device, and get results within 10 to 30 minutes via smartphone technology. Gene-Z was unveiled November 7 at a conference of the National Plant Diagnostic Network at the University of California, Berkeley.
“We’ve already successfully proven Gene-Z’s capacity for quantifying cancer markers,” inventor Syed Hashsham, a professor of civil and environmental engineering at Michigan State University, was quoted in a release from the university. “With this application, we can speed the analysis of pathogens in plants, water and food with the ultimate goal of improving the safety and security of food supplies anywhere in the world.”
As reported recently by Miller-McCune, new technologies invented at the University of California can convert cellphones into microscopes, making it possible to for doctors in rural villages far from hospitals to identify malaria, parasites and HIV antibodies in blood smears.
Gene-Z uses an iPod Touch or Android-based tablet to identify a plant pathogen and its genetic makeup and calculate its amount. Gene-Z already has been used to test a new disease that is devastating cucumber crops in the United States, researchers said. The device is ready to be manufactured, and Hashsham is working with MSU Technologies to bring it to market.
