Graduate student Lu Xu wears a device designed by engineers, at Washington University in St. Louis, that targets ultrasound waves to precise spots in the brain. Such targeting is the first step in a sonobiopsy, a noninvasive technique invented by Washington University researchers that uses ultrasound and microbubbles to release biomolecules from brain tumors. The biomolecules then can be collected via a blood draw, analyzed and used to inform treatment decisions. Xu is part of a research team that demonstrated that sonobiopsy is safe and feasible for use in people.

Benjamin Sumlin, PhD, a senior scientist at Washington University in St. Louis, blows into a device designed by researchers at the university. The device — a breath test that uses a biosensor — could become a tool for use in doctors’ offices to quickly diagnose people infected with the virus that causes COVID-19.
