However, even then we are confronted with a confounded polydispersity of both optical and colloidal/hydrodynamic properties. In the left side of Fig. 2, the assumed core-shell structure of a β-carotene microparticle is shown (Auweter et al. 1999). Such a complex hybrid particle exhibits several levels of polydispersity, which impact the distribution of sedimentation coefficients observed in an AUC. They are for example:diameter of the inner core;\nchemical composition, esp. oil content, of the inner core;\nconcentration of the adsorbed protection colloid (gelatin);\ndegree of swelling of the gelatin.","divisions":[{"label":"p","span":{"begin":599,"end":626}},{"label":"p","span":{"begin":627,"end":685}},{"label":"p","span":{"begin":686,"end":745}}],"tracks":[]}
