A diamond-based quantum sensor inserted into a living cell can provide previously unseen levels of detail about how life works and how diseases form. "Think of it as an EKG for a single cell—a way to capture everything happening inside at once, in real time," said University of Chicago Pritzker School of Molecular Engineering professor Aaron Esser-Kahn. "We routinely monitor vital signs in people—heart rate, breathing, temperature—but until now, there simply hasn't been an equivalent way to take a cell's vitals."
