Work with microscopes typically relies on the intensity of emitted or reflected light. A method called fluorescence lifetime imaging microscopy is different, focusing instead on how quickly emitted light disappears. The rising and falling patterns in this image are derived from the lifetimes of fluorescent light emitted by reactants and products as they swirl together inside a tiny network of channels, providing a novel view of how these molecules interact.
