To demonstrate the potential of their method, the team analysed the metabolites inside plant cells from an Allium cepa (onion) bulb. In the first step, a microdissection needle cuts a hole


in the cell membrane while leaving the organelles intact. Only a single cell is cut open during dissection and the neighbouring cells remain undamaged. In the next step, an optical fibre


with a 15-μm tip is used to direct a laser IR pulse at a specific region. The pulse creates a plume of ejected material that is ionized and characterized using electrospray mass spectrometry


to identify the metabolites present. The sharpened tip of the optical microfibre is a similar size to the cell nucleus, which enables the team to selectively ablate it — although some cross


contamination with the surrounding cytoplasm is inevitable. Aiming the optical fibre solely at the cytoplasm allowed for the selective analysis of the metabolites present outside the


nucleus.
