New imaging technique helps resolve nanodomains, chemical composition in cell membranes – Phys.org

For those not involved in chemistry or biology, picturing a cell likely brings to mind several discrete, blob-shaped objects; maybe the nucleus, mitochondria, ribosomes and the like.
There’s one part that’s often overlooked, save perhaps a squiggly line indicating the cell’s border: the membrane. But its role as gatekeeper is an essential one, and a new imaging technique developed at the McKelvey School of Engineering at Washington University in St. Louis is providing a way to see into, as oppo…
