MIMS images of Teredinibacter turnerae, a nitrogen-fixing bacterium inhabiting a shipworm gill. The 12C15N/12C14N image (left) allows the uptake of 15N by these organisms to be quantified. On the right, the image of 12C15N- ions shows that sensitivity is sufficient to image the flagellum of this bacterium (arrowed) even though the flagellum diameter is estimated from the ion signal to be only about 10 nm.
