✦ Synopsis

Using a femtosecond laser-based technique,
spectrochemical analysis of leaf samples is demonstrated. The
study is exemplified for Fe. Standard reference concentrations –
internal standards – of Fe in the two leaf samples were measured
using the method of Relaxation Weighted Magnetic Resonance
Imaging. From the spectra obtained using Laser Induced Breakdown
Spectroscopy technique, spatial distribution of Fe within the leaf
was identified. Thus, this technique could potentially be used as
a complementary technique for identification of storage and
trafficking of iron ions within different plant compartments. In
particular, individual plant cells can be investigated without
collateral damage with high spatial distribution.
