Abstract
A synthetic polymer based surface is coated with polymer particles without the use of an adhesive. A top surface layer is swollen or semidissolved by contacting with a solvent such as acetone, polymer particles are contacted with the surface to partially embed the particles in the surface layer, and the surface layer is dried. The polymer particles are either dry or in a slurry when contacted with the surface, and contact with the polymer particles may be simultaneous or subsequent to contacting with the solvent. The particles may be particles for chromatography, and may be derivatized before or after contacting with the surface such as by coupling an enzyme, DNA, an antibody or an antigen.
