Detection of Nanoparticle in Plant Tissue

Caption

Highly sensitive spectral analysis techniques at the ESRF enabled detecting otherwise undetectable nanoparticles of cerium dioxide in the soya beans. This image shows the X-ray fluorescence intensity in an area of about 0.5 by 0.5 mm2. The nanoparticle is indicated by a red pixel (high fluorescence) in the upper left quarter.
