Query: Single DNA Electron Spin Resonance Spectroscopy in Aqueous Solutions   Magnetic resonance spectroscopy of single biomolecules under
near-physiological conditions may substantially advance understanding of
biological function, yet remains very challenging. Here we use nitrogen-vacancy
centers in diamonds to detect electron spin resonance spectra of individual,
tethered DNA duplexes labeled with a nitroxide spin label in aqueous buffer
solutions at ambient temperatures. This paves the way for magnetic resonance
studies on single biomolecules and their inter-molecular interactions in a
native-like environment.
