胶体和蛋白质溶液中多分散性和各向异性的影响:积分方程方法

Effect of Polydispersity and Anisotropy in Colloidal and Protein Solutions: an Integral Equation Approach

Domenico Gazzillo, Achille Giacometti

摘要:

综述了积分方程理论在复杂流体中的应用,特别强调了多分散性和各向异性对其结构和热力学性质的影响。积分方程的解析解和数值解都在一组已被广泛应用于文献中的最小势能模型的范围内进行了讨论。虽然其他流行的理论工具,如数值模拟和密度泛函理论,是优越的定量和准确的预测,我们认为,积分方程理论仍然提供,在简单的流体,一个宝贵的技术,能够捕捉到的主要基本特征的复杂系统,在一个低得多的计算成本。此外,它可以提供任意帧中的角度依赖性的详细描述,而不像数值模拟那样,这种信息经常受到统计数据不足的阻碍。胶体混合物,球状蛋白质和斑片状胶体的应用进行了讨论,在一个统一的框架。

英文摘要:

Application of integral equation theory to complex fluids is reviewed, with particular emphasis to the effects of polydispersity and anisotropy on their structural and thermodynamic properties. Both analytical and numerical solutions of integral equations are discussed within the context of a set of minimal potential models that have been widely used in the literature. While other popular theoretical tools, such as numerical simulations and density functional theory, are superior for quantitative and accurate predictions, we argue that integral equation theory still provides, as in simple fluids, an invaluable technique that is able to capture the main essential features of a complex system, at a much lower computational cost. In addition, it can provide a detailed description of the angular dependence in arbitrary frame, unlike numerical simulations where this information is frequently hampered by insufficient statistics. Applications to colloidal mixtures, globular proteins and patchy colloids are discussed, within a unified framework.
