Abstract: The present invention pertains to products and processes relating to sulfonating molecules, including nucleic acids, amino acids, peptides, polypeptides, oligomers, polymers, and copolymers. The disclosed process allows for a uniform and controlled level of sulfonating molecules. The sulfonated molecules produced by the disclosed process exhibit a high degree of uniform sulfonation as well as improved properties.
Abstract: Sulfonated styrene copolymer compositions and salts thereof, and their use in drug delivery devices, such as wound dressings, as well as their use for controlling chemical agents and for controlling biological organisms are presented.
Abstract: Sulfonated styrene copolymers are useful for inhibiting elastase and/or collagenase and for promoting angiogenesis in a wound, and for controlling biological organisms on a porous surface. Compositions for these uses may include a tetracycline, an amino acid and/or a sulfonated styrene copolymer in salt form, especially an ammonium salt.
Abstract: Wound dressings and coated implantable medical devices include a styrene sulfonate polymer. Organic and inorganic therapeutic agents may be incorporated in the copolymer. Inorganic therapeutic agents are oligodynamic metals, especially silver.
