| The prototype system has shown how MIMS images can be used to study bacteria. These images measure (a) the 12C14N- ion, (b) the 12C15N- ion , and (c) the ratio of 12C14N-/12C15N- ions in the bacteria sample. The magenta color indicates the cells that have incorporated nitrogen-15 isotope. [Credit: Lechene/Journal of Biology] |
