Rice University study examines how nanoparticles behave in food chain


Date: 22/02/2015


Scientists of Rice University, Houston, USA, traced the uptake and accumulation of quantum dot nanoparticles from water to plant roots, plant leaves and leaf-eating caterpillars. 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 varied significantly depending upon the type of surface coating applied to the particles. The research is available online in the American Chemical Society's journal Environmental Science & Technology.
