New Nanoparticle-Based Sensors Can Measure Residual Herbicides in Food

Reporting in the journal Food Chemistry, a Washington State University research team used two testing methods to measure the levels of two herbicides, namely atrazine and acetochlor, in samples of apples, strawberries, cabbage, corn, and fruit juices. The work shows the real-world viability of their easy-to-use and inexpensive methods of testing.
