Rice University study examines how nanoparticles behave in the food chain
This comprehensive laboratory study, one of the first to examine how nanoparticles move through human-relevant food chains, found that nanoparticle accumulation in both plants and animals varies significantly depending on the type of surface coating applied to the particles. Scientists at Rice University, Houston, USA, traced the uptake and accumulation of quantum dot nanoparticles from water to plant roots, leaves and leaf-eating caterpillars. The study, published in the American Chemical Society's journal Environmental Science & Technology, is available here.
