Synchrotron Micro-XRF and Micro-XANES Confirmation of the Uptake and Translocation of TiO2 Nanoparticles in Cucumber Plants Advances in nanotechnology have raised concerns about possible effects of engineered nanomaterials in the environment, especially in terrestrial plants. In this research, the impacts of TiO2 nanoparticles were evaluated in hydroponically grown cucumber plants.
