Detection of substances on the single-molecule level could provide a helpful too for pharmacology, medicine, and product safety. But toxic or otherwise unwanted substances sometimes have a low molecular weight, making them hard to sense. To make a sensor for these molecules, you need materials with special properties, such that their interactions trigger an abrupt change in behavior.
