Abstract
A biometric method includes: a step () for administering, to a target organism from the outside thereof, one of (i) a target molecule A having both an unpaired electron and a magnetic resonance nucleus having a gyromagnetic ratio smaller than the same ofF, and (ii) a target molecule B and a radical molecule C, the target molecule B having no unpaired electron, and further having a magnetic resonance nucleus having a gyromagnetic ratio smaller than the same ofF, the radical molecule C having an unpaired electron; and a step () for causing electron spin resonance in the unpaired electron of the target molecule A or the radical molecule C by irradiating electromagnetic waves to the target organism, subsequently triggering nuclear magnetic resonance in the magnetic resonance nucleus having a gyromagnetic ratio smaller than the same ofF in one of the target molecule A and the target molecule B, and further, measuring nuclear magnetic resonance signals. The step () is carried out in a magnetic field having such an intensity that the nuclear magnetic resonance signals of the magnetic resonance nucleus in one of the target molecule A and the target molecule B are degenerated, the magnetic resonance nucleus having a gyromagnetic ratio smaller than the same ofF. The biometric method makes it possible to measure low-sensitivity magnetic resonance nucleus such asC,N, andP, which are important nuclides present in organism, with performance equal to or over that of a high-field MRI device.
