    摘要： A process for preparing nanoparticle coated surfaces including the steps of electrostatically coating surfaces with polyelectrolyte by exposing the surface to a solution or suspension of polyelectrolyte, removing excess non-bound polyelectrolyte, then further coating the particles with a multi-layer of charged nanoparticles by exposing the polyelectrolyte-coated surface to a fluid dispersion including the charged nanoparticles. The process steps can optionally be repeated thereby adding further layers of polyelectrolyte followed by nanoparticles as many times as desired to produce a second and subsequent layers. The polyelectrolyte has an opposite surface charge to the charged nanoparticles and a molecular weight at the ionic strength of the fluid that is effective so that the first, second, and subsequent layers independently comprise a multiplicity of nanoparticle layers that are thicker than monolayers.

    摘要： The present invention relates to microparticles, particularly spherical silica microparticles, which may be useful in liquid chromatography. Specifically, the microparticles include a solid core and an outer porous shell surrounding and irreversibly joined to the core. The shell is composed of a plurality of colloidal nanoparticles, which are applied using an electrostatic multi-multilayering method. The resulting microparticles have a small particle diameter, such as about 1 μm to 3.5 μm, a high particle density, such as about 1.2 g/cc to 1.9 g/cc, and a high surface area, such as about 50 m2/g to 165 m2/g. These microparticles can be used to form packed beds and liquid chromatographic columns, which are more efficient and rugged than conventional liquid chromatographic columns.
