Abstract:
1. An optically integrated magnetic biosensor based on optically detected magnetic resonance (ODMR) comprises: an ODMR center; a fluidics layer configured to contain a solution comprising analytes, the fluidics layer being disposed over the ODMR center; a light source configured to generate incident light which excites electrons within the ODMR center from a ground state to an excited state; and a radio frequency (RF) antenna configured to generate an RF field incident on the ODMR center, the RF antenna being further configured to generate the RF field with frequencies which correspond to ground state transitions in the ODMR center; in which the ODMR center produces emitted light when illuminated by the incident light, characteristics of the emitted light being influenced by the RF field and magnetic nanoparticles attached to the analytes.
