Hunting small molecules: The graphic shows the experimental setup used to detect small molecules, like those used for most pharmaceutical drugs (green) and their binding interactions with membrane protein receptors (yellow). These events can be imaged using conventional or phase contrast microscopy through the process of differential optical detection. Subtle distortions in the cell membrane shape caused by the binding or dissociation of small molecules are translated into observable changes in light intensity.
