Quantum properties in atom-thick semiconductors offer new way to detect electrical signals in cells

For decades, scientists have relied on electrodes and dyes to track the electrical activity of living cells. Now, engineers at the University of California San Diego have discovered that quantum materials just a single atom thick can do the job—using only light. For decades, scientists have relied on electrodes and dyes to track the electrical activity of living cells.
