image: Single molecule electron spin resonance spectrometer: The future of a magnetic resonance spectrometer for a single biomolecule in situ. A single nitrogen-vacancy inside a diamond is used to image a DNA or protein inside a live cell. Shi et al. reported a first step toward such a machine by demonstrating detection of a single protein Electron Spin Resonance spectrum under ambient conditions. This material relates to a paper that appeared in the March 6, 2015, issue of Science, published by AAAS. The paper, by F. Shi at University of Science and Technology of China (USTC) in Hefei, China, and colleagues was titled, 'Single-protein spin resonance spectroscopy under ambient conditions.' view more
