Abstract:
This short review aims to summarize the current developments and applications of mass spectrometry-based methods for in situ profiling and imaging of plants with minimal or no sample pre-treatment or manipulation. Infrared-laser ablation electrospray ionization and UV-laser desorption/ionization methods are reviewed. The underlying mechanisms of the ionization techniques-namely, laser ablation of biological samples and electrospray ionization-as well as variations of the LAESI ion source for specific targets of interest are described.
