An improved device is provided which may be used, e.g. for immunoassay of lipopolysaccharides or for removing LPS pyrogens from aqueous solutions, or for removing LPS endotoxins from wounds. Such device comprises, in combination, a substrate, e.g. plastic, i.e. polystyrene, polycarbonate, polymethylmethacrylate or polyvinyl chloride, or a woven cloth, i.e. a rayon/polyester cloth or a polyester cloth, or a non-woven cloth, i.e. a rayon/polyester cloth, or a polyester cloth, or paper, which is adapted to receive a sample to be tested, and an oligopeptide, or a hydrophobic polypeptide or a polymyxin, e.g. polymyxin B, polymyxin B1, polymyxin B2, polymyxin D1, polymyxin D2, or polymyxin E, adhered to the substrate.
