Fig. 5

Raman spectra of haemin, sHz, nHz and HLC. Haemin (a), synthetic haemozoin also called β–Haematin (b), native haemozoin from P. falciparum (c); and Haemozoin-like crystals (HLC) (d). Spectra were obtained using 632.8 nm laser excitation. Identical lines of sHz and nHz, while HLC shows a different pattern.
