    Developing micron-sized magnetic resonance

    Harvard scientists have developed a system that uses nitrogen-vacancy centers — atomic-scale impurities in diamonds — to read the nuclear magnetic resonance signals produced by samples as small as a single cell — and they did it on a shoestring budget using a 53-year-old, donated electromagnet.

    Diamonds are a lab’s best friend

    Using the atomic-scale quantum defects in diamonds known as nitrogen-vacancy centers to detect the magnetic field generated by neural signals, scientists working in the lab of Ronald Walsworth, a faculty member in Harvard’s Center for Brain Science and Physics Department, demonstrated a noninvasive technique that can show the activity of neurons.
