What is Structure and thermodynamics of nonideal solutions of colloidal particles: Investigation of salt-free solutions of human serum albumin by using small-angle neutron scattering and Monte Carlo simulation about?
The understanding of the structural and thermodynamic properties of moderately or highly concentrated solutions is fundamental, e.g., in medicine and biology and also in many technical processes. In this work, we have used the small-angle neutron scattering method (SAN!%), in combination with Monte Carlo simulation, to study salt-free solutions of human serum albumin (HSA) in the concentration range up to 0.26 g ml-'. The model calculations of the theoretical SANS intensities are quite general, thus avoiding the approximation that the relative positions and orientations of the particles are independent of each other. The computation of the theoretical intensities also includes the calculation of a 'thermodynamic' intensity scattered at zero angle, which is obtained via the nonideal part of the chemical potential. The latter quantity is obtained by applying the test particle method during the Monte Carlo simulations. It is found that the SANS data can be explained by a model where the HSA molecules behave as hard ellipsoids of revolution with semiaxes a = 6.8 nm, b = c = 1.9 nm. In addition to the hard core interaction, the particles are also surrounded by a soft, repulsive rectangu
