Figure 3

Real RI increment of oxygenated human RBCs. The blue line is the arithmetic mean of the individual curves in Fig. 2 (underlying data available as Supplementary Data S1). Various literature values for the RI increment of oxygenated Hb solutions and RBCs are shown for comparison. Samples for these measurements were: (i) Hb solutions from powder32,33,34, (ii) Hb solutions from freshly hemolysed RBCs28,35 and (iii) single native RBCs39. The Kramers-Kronig computation38 matched to Ref.28 shows the RI dispersion expected from the accurately known extinction spectrum γ(λ).
