Using a 53-year-old electromagnet, Ron Walsworth has developed a system that uses atomic-scale impurities in diamonds to read nuclear magnetic resonance signals produced by samples as small as a cell.

PH.D. candidates Jenny Schloss (left) and Matthew Turner are co-authors of a recent paper on using nitrogen vacancy centers — atomic-scale impurities in diamond — to track neural activity. “We want to understand the brain from the single-neuron level all the way up, so we envision that this could become a tool useful both in biophysics labs and in medical studies,” said Schloss.
