1. An in vivo imaging agent, comprising:

  • a plurality of functionalized magnetic nanoparticles, wherein each of the functionalized magnetic nanoparticles is functionalized to selectively interact with an analyte in an environment; and

    a plurality of functionalized nanodiamonds, wherein each of the functionalized nanodiamonds contains at least one color center and is functionalized to selectively interact with the analyte in the environment, and wherein the at least one color center is configured to emit light in response to illumination, wherein the emitted light has one or more properties relating to proximity between the at least one color center and individual functionalized magnetic nanoparticles of the plurality of functionalized magnetic nanoparticles.
