Unformatted text preview: en a material in a serum or an electrolyte solution, you must think about what molecules are contain in each solution. An electrolyte solution is composed of ions while a serum contains proteins and other organic molecules. The DLVO theory says that non ­specific attractive forces come mostly from Van der Waals forces and hydrogen bonding. Attractive forces are slightly large than repulsive forces. The electrolytes in the solution will exhibit stronger electrostatic effects than the serum from all the charged particles. The molecules in the serum will probably have higher molecular weight resulting in stronger Van der Waals forces. The serum would have more surface adsorption. b.) Bones need tendons and ligaments to attach to the surface to facilitate movement. The surface of bones would want cells to be able to attach to it...
