Membrane proteins are the “gatekeepers” that allow information and molecules to pass into and out of a cell. Until recently, the microscopic study of these complex proteins has been restricted due to limitations of “force microscopes” that are available to researchers and the one-dimensional results these microscopes reveal.
Now, researchers have developed a three-dimensional microscope that could yield unparalleled study of membrane proteins and how they interact on the cellular level. These microscopes could help pharmaceutical companies bring drugs to market faster.
