Single-molecule methods leap ahead

Much of our knowledge about biological systems has been obtained by examining ensembles of molecules. However, this has begun to change because of the unprecedented precision and clarity afforded by single-molecule measurements. The last decade has seen amazing advances in the resolution and complexity of these methods, making it possible to ask and answer entirely new types of biological questions.
