Fig. 3.

Refractive index dispersion for pure low molecular weight (5 kDa) dextran and iron oxyhydroxide polysaccharide aqueous suspensions studied at room temperature (c ^Fe = c ^P = 1 g/L). The inset shows the temperature dependence of the refractive index for λ = 656.3 nm. The wavelength and temperature dependences of n for Fe-dextran and Fe-dextran (S) are identical within the error (the size of the error bar is smaller than the dimension of the experimental point)
