Researchers have developed a tiny sensor for detecting pesticides on fruit in just a few minutes. The technique uses flame-sprayed nanoparticles made from silver to increase the signal of chemicals. While still at an early stage, the researchers hope these nano-sensors could help uncover food pesticides before consumption.Researchers have developed a tiny sensor for detecting pesticides on fruit in just a few minutes.
