    Abstract: Hydrophobic polymer surfaces whose level of protein binding is less than about 50-80 ng/cm are achieved by: (1) applying a coating solution composed of a solvent and a non-ionic surfactant having an HLB number of less than 5 to the surface; and (2) drying the surface to remove the solvent and thereby bring the surfactant into direct contact with the hydrophobic polymer. The combination of a low HLB number and the drying step have been found to produce low binding surfaces which can withstand multiple washes with water and/or protein-containing solutions. Alternatively, the low binding surfaces can be produced by applying the non-ionic surfactant to the mold surfaces which contact molten polymer and form the polymer into a desired shape, e.g., into a multi-well plate, a pipette tip, or the like. Further, the low binding surfaces may be produced by incorporating non-soluble, non-ionic surfactants having an HLB number of less than or equal to 10 into a polymer blend prior to molding the article.

    Abstract: A method for making an activated carbon composite which involves providing a cross-linkable resin and a support material which is wettable by the resin. The support material can be cotton, chopped wood, sisal, non-fugitive material, and combinations of these. The support is contacted with the resin; and the resin and support material are dried. The resin and support material are then shaped, the resin is cured, and the resin and any carbonizable material are carbonized. The carbon is then activated to produce the product composite. An activated carbon composite produced by the above described method in which the carbon is in the form of a continuous structure reinforced by and uniformly distributed throughout non-fugitive support material.
