Globular colloids, interactions with

To study gelation phenomena in globular proteins, colloid dispersions, etc., Baxter s adhesive hard sphere (AHS) system [38] is often used as a model system. Particles in the AHS system interact with each other through strongly attractive short-range square well potentials.

Macromolecules in solution having molecular weights of tens of thousands or more were often called colloids, but now we know they generally form true solutions. The diffusion behavior of protein macromolecules in solution is affected by their large sizes and shapes, which can be random coils, rodlike, or globular (spheres or ellipsoids). Also, interactions of the large molecules with the small solvent and/or solute molecules affect the diffusion of the macromolecules and also of the small solute molecules.

Modification of the globular aromatic surface of [60]fiillerene with various func-tionahties creates an amphiphUic nature on the [60]fuUerene molecule, which allows for the production of Uquid crystalline phases, vesicles, colloidal clusters and bilayer structures. The amphiphihc interactions among the [60]fuUerene molecules are obviously crucial in determining the supramolecular organization formed.
