“…The binding is most likely due to a negative electrostatic charge on the surface of latex spherules (22). The partial release of the bound enzyme from the latex by salt solution would be in accordance with this.…”

“…The particles (contained in 200 ml of dispersion diluted to a weight concentration of 20%) were successively mixed with 100 g Dowex 50WX8 sulfonic acid resins and Dowex 1X8 quaternary ammonium resin. The resins were conditioned according to [11] and were stirred with the aqueous dispersion several hours. The resulting dispersion was filtered to remove flocs, diluted with ethanol, and dialyzed against ethanol (technical grade) for one week.…”

We report a study of mixtures of initially oppositely charged particles with similar size. Dispersions of silica spheres (negatively charged) and alumina-coated silica spheres (positively charged) at low ionic strength, mixed at various volume ratios, exhibited a surprising stability up to compositions of 50% negative colloids as well as spontaneous repeptization of particles from the early-stage formed aggregates. The other mixtures were found to contain large heteroaggregates, which were imaged using cryogenic electron microscopy. Electrophoretic mobility, electrical conductivity, static and dynamic light scattering and sedimentation were studied as a function of volume fraction of the mixed dispersions to investigate particle interactions and elucidate the repeptization phenomenon.
