Inside our cells, proteins and other biomolecules come together to form molecular complexes as part of the mechanisms that keep the cells running. These interactions sometimes are fleeting. For example, as new proteins are synthesized, the growing chain interacts off and on with other proteins called chaperones that ensure the new one folds correctly. A new microfluidic device could help researchers study short-lived molecular complexes involved in key biological processes, capturing . . .
