Sensing single proteins with diamonds Nuclear magnetic resonance is a powerful technique for medical imaging and the structural analysis of materials, but usually associated large-volume samples. Lovchinsky et al. exploited properties spin defect in diamond manipulated it quantum-logic protocol. They demonstrated detection spectroscopy multiple nuclear species within individual ubiquitin attached to specially treated surface at room temperature. Science , this issue p. 836
