FIG. 5.
Synthetic hemozoin. (a) Confocal reflection image (excitation at 405 nm) of synthetic hemozoin nanocrystals on a diamond substrate. In total, 46 dark features are identified as likely hemozoin nanocrystals. (b) Corresponding diamond-magnetic-microscopy image at B0 = 350 mT. 41 of 46 possible crystals exhibit an observable magnetic feature. (c) ΔB(B0) curves for three synthetic hemozoin crystals labeled in (b). Solid lines are weighted linear fits. (d) Histograms of dΔB/dB0 for natural and synthetic hemozoin crystals.
