Abstract
A method of inducing spin polarization in an analyte is provided. The method exposes 14N spin defect centers embedded within 25 nm of a diamond surface to a magnetic field while an analyte is near the surface. The 14N spin defect centers are polarized by treatment with an electromagnetic wave protocol having a visible light pulse (p0); a microwave pulse (mw1), a radio frequency pulse (rf1), a microwave pulse (mw2) and a radio frequency pulse (rf2) resulting in polarization of the nuclear spins of the 14N spin defect centers. Polarized spins in the 14N spin defect centers induce spin polarization in the analyte.
