How are chemicals distributed in a cell? Scientists have developed a combined mass spectrometry and biological imaging device that enables direct, label-free detection, and high-resolution mapping of chemicals inside a biological cell. The distribution and accumulation of the disinfectant proflavine around the cell organelles could be visualized directly, based on the mass signal from the molecule.
