Uptake and Distribution of Ultrasmall Anatase TiO2 Alizarin Red S Nanoconjugates in Arabidopsis thaliana
Nano letters, 2010•ACS Publications
While few publications have documented the uptake of nanoparticles in plants, this is the
first study describing uptake and distribution of the ultrasmall anatase TiO2 in the plant
model system Arabidopsis. We modified the nanoparticle surface with Alizarin red S and
sucrose and demonstrated that nanoconjugates traversed cell walls, entered into plant cells,
and accumulated in specific subcellular locations. Optical and X-ray fluorescence
microscopy coregistered the nanoconjugates in cell vacuoles and nuclei.
