Food scientists create novel magnetic nanoparticles for rapid screening of pesticide residue in vegetables
(PHYSorg.com Chemistry)

Food scientists from the National University of Singapore (NUS) developed a rapid and highly sensitive screening technique capable of detecting minute amounts of pyrethroids in vegetables, a common type of synthetic pesticide applied on agricultural crops. The innovative strategy makes use of magnetic nanoparticles to simplify pyrethorid extraction, reducing the screening process to under two hours.
