Diamond magnetic sensing and imaging

POSTER

Abstract

Diamond magnetic sensing has emerged as a powerful tool to detect nanomagnetism in biological and solid-state samples, as well to measure weak signals from nuclear spins and spin textures of molecules. We report ongoing experiments that explore several applications of diamond magnetic sensing. These include: (i) microfluidic nuclear magnetic resonance spectrometer capable of sensing small quantities (< 1 pL) of analyte [1], achieving spectral resolutions capable of distinguishing proton with heteronuclear J splittings; (ii) a wide-field magnetic microscope able to measure the stray magnetic fields produced by individual malarial hemozoin biocrystals (size < 300 nm) [3] and magnetization relaxation of single magnetic nanoparticles (size < 25 nm) at room temperature and as a function of applied field up to 350 mT.
