| Popis: | Semi-solid viscoelastic matrices produced out of lysozyme in organic/aqueous media [tetramethylurea (TMU)/water] were characterized by small angle X-ray scattering (SAXS). The scattering curves were modeled in their form and interference factors. Radii of gyration of scattering particles were found to undergo a dramatic increase from 14 A in water to approximately 44 A in the matrices. Average correlation distances d=155 A were consistently verified for the scattering particles in the matrices, irrespective of solvent composition (in the 0.6 |
