12 . A method, comprising:
generating a comparison between (a) a detected scattering profile information associated with a plurality of target regions within a biological tissue interrogated by a dark-field interrogation stimulus in the presence of a magnetic field stimulus and (b) reference hemozoin dark field scattering information; and magnetically perturbing hemozoin nanoparticles in the biological tissue based in part on the comparison.
13 . The method of claim 12 , wherein generating the comparison includes comparing, using circuitry, a detected scattering profile associated with a plurality of target regions within a biological subject interrogated by a multiplexed dark-field interrogation stimulus in the presence of a magnetic field stimulus and reference hemozoin dark field scattering information.
