Synthesis, Application, and Tracking of Magnetic Carbon-Coated Nanoparticles in Plants

The behavior of nanoparticles inside plants is gaining importance for its implications in research about putative applications and toxicology. Magnetic carbon-coated nanoparticles can be easily traced through plant tissues using simple and affordable histological techniques. Here we present a methodology for the synthesis of such nanoparticles. We also describe methods for growing plants using rhizotrons (in order to observe the roots), procedures for applying the nanoparticles, taking and processing the samples.
