Description:
Extending magnetic resonance imaging to the atomic scale has been a long-standing aspiration, driven by the prospect of directly mapping atomic positions in molecules with three-dimensional spatial resolution. We report detection of individual, isolated proton spins by a nitrogen-vacancy (NV) center in a diamond chip covered by an inorganic salt. The single-proton identity was confirmed by the Zeeman effect and by a quantum coherent rotation of the weakly coupled nuclear spin. Using the hyperfine field of the NV center as an imaging gradient, we determined proton-NV distances of less than 1 nm.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Loretz, M -- Rosskopf, T -- Boss, J M -- Pezzagna, S -- Meijer, J -- Degen, C L -- New York, N.Y. -- Science. 2014 Oct 16. pii: 1259464. doi: 10.1126/science.1259464.
