Bryan Allinson has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Buffer polymers, co-immobile buffer and enzyme polymers and methods of synthesis thereof
    Patent number: 6762213
    Abstract: A polyurethane polymer includes at least one buffer selected to adjust pH to a pH within a desired range. The buffer compound is immobilized within the polymer, and the polymer has a buffer capacity in excess of 3 micromoles of acid or base per gram polymer. A polymer includes at least one enzyme that is selected to catalyze a reaction of a substance. The enzyme is immobilized within the polymer. The polymer also includes at least one buffer selected to adjust the pH in the vicinity of the enzyme to a pH within a desired range. The buffer compound is also immobilized within the polymer. The polymer preferably has enzyme activity and a buffer capacity in excess of 3 micromoles acid or base per gram polymer. In one embodiment, each of the enzyme(s) and the buffer(s) are covalently bonded to the polymer.
