文摘

Uptake and transport of ENMs in plants can be studied with synchrotron based micro/nanoprobes. X-ray fluorescence maps and absorption spectroscopy provide elements distribution and speciation. Sample preparation should preserve morphology, elements distribution and speciation at all scales. Cryogenic conditions maintain samples close to in-vivo state and reduce radiation damage. Data analysis software should handle large hyperspectral data sets.
