Ample evidence suggesting that carriers of hemoglobin S and C are protected from life-threatening malaria, but little is known about the underlying biochemical mechanisms at the single cell level. Using nano-focused scanning X-ray fluorescence microscopy, we quantify the spatial distribution of individual elements in subcellular compartments, including Fe, S, P, Zn, and Cu, in Plasmodium falciparum-infected erythrocytes carrying the wild type or variant hemoglobins.
