The effect of polydispersity in the macromolecule size and surface potential on the depletion attraction and structural repulsion between two charged spherical particles in a solution of nonadsorbing charged spherical macromolecules was investigated using a modified form of the force-balance model o
## Abstract **Summary:** We investigate the influence of the polydispersity of colloidal particles and polymer, respectively, on the form factor and depletion interaction by using the laser distribution for parallel plates immersed in a solution of nonadsorbing polymers. For colloidal particles, we
The hydrodynamic radii of colloidal silica particles in the aqueous solutions were measured under various conditions of \(\mathrm{pH}\) and salt concentration by means of the dynamic light scattering technique. In the salt free solutions the observed hydrodynamic radius increased by \(1 \mathrm{~nm}
