Abstract:
1. A method for preparing a biomolecular hybrid material, comprising the steps of: (a) chemically attaching one or more seed enzymes to the surface of a carbon nanotube (CNT) to immobilize said enzyme or enzymes on said CNT; (b) forming one or more enzymes into clusters by crosslinking said enzymes with a crosslinking agent in solution, thereby forming crosslinked enzyme clusters (CECs); (c) precipitating said CECs from said solution to isolate said CECs; and (d) chemically attaching said CECs to said seed enzymes by contacting said CECs and said immobilized seed enzymes with said crosslinking agent, wherein said CECs have a thickness that provides an enzyme activity that is greater than the activity of the same one or more enzymes in the CECs in a monolayer configuration on said surface of said CNT.
