Direct and quick molecular analysis of live plant single cells viewed under a video-microscope has been developed in their intact undamaged environment using nano-electrospray tip and mass spectrometers. This method has been successful in identifying specific molecules in plant live single-cell analysis by mass spectrometry, and opens the possibility to compare different cell types from different tissues with morphological evidence in undamaged plants.
