Characterization of hemozoin (Hz) alone used for calibration of Cytophone and PTM systems. (a) STEM image of Hz clusters. TEM images of a single (b) and clustered (c) Hz. (d) Absorption spectrum of synthetic Hz. Spectral absorbance of Hz and for comparison magnetic microparticles with a diameter of 5.5 µm. Transmission/bright field (e) & (g) and photothermal (f) & (h) images of small individual Hz at low concertation (5 µg/mL) after ultrasound treatment (24 kHz, 5 min) and clustered Hz at high concertation (25 µg/mL). (i) Histogram of Hz crystal size distribution obtained with photothermal microscopy (PTM); error bars present standard deviation, n = 55.
