Preparation of a Functional Enzyme–Carbon Nanotube Complex by the Immobilization of Superoxide Dismutase on Single-Wall Carbon Nanotubes

Abstract

This paper describes a method for synthesizing single-wall carbon nanotubes (SWCNTs) and preparing a functional enzyme-carbon nanotube complex possessing antioxidant properties via the immobilization of superoxide dismutase on SWCNTs. spectrophotometry has shown that the inhibition of adrenochrome formation was accelerated by an increased added concentration of this enzyme-carbon nanotube complex. This indicates the successful immobilization of superoxide dismutase and functional activity of the superoxide dismutase (SOD)–SWCNT complex, which can be used in nanomedicine for delivering active SOD to tissues and cells.
