University of Sao Paulo develops sensors to detect trace amounts of pesticides present in fruits and other plants
Researchers from researchers at the University of Sao Paulo (USP) in Brazil have created an electrochemical device made from kraft paper which detects the presence of pesticides in fruits and vegetables in real-time when coupled with the electronic gadget. For an apple or a cabbage for instance it detects carbendazim which is a popular fungicide employed in Brazil although it has been restricted. The latest device is extremely sensitive and is similar to diabetes glucometers that diabetics use to monitor blood sugar levels but the outcomes of food-based scanning for pesticides can be shown on a smartphone. "In the tests we [...]
