PECASE Honoree Elizabeth Nance Highlights the Importance of Collaboration in Nanotechnology

A network of capillaries supplies brain cells with nutrients. Tight seals in their walls keep blood toxins—and many beneficial drugs—out of the brain.

It keeps invaders and other toxins from entering the human brain by screening out dangerous molecules. But the intricate workings of this extremely effective barrier also make it challenging to design therapeutics that would help us. And as it turns out, getting a drug across the blood-brain barrier is only half the battle. Once it’s across, the drug needs to effectively target the right cells in the brain tissue. With this in mind, it’s no surprise that challenges this complex are solved through collaboration among scientists from several different specialties. Elizabeth Nance , an assistant professor of chemical engineering at the University of Washington in Seattle and a recent recipient of the Presidential Early Career Award for Scientists and Engineers (PECASE), focuses her research on understanding the barriers in the brain and other cell- and tissue-based barriers in the body to see how nanoparticles interact with them. Her lab uses nanoparticles to package therapies that will treat newborn brain injury, which can occur when the brain loses oxygen and blood flow, often during or immediatel...
