Covalent immobilization of tyrosinase onto commercial multi-walled carbon nanotubes and its effect on enzymatic activity

Abstract

Multi-walled carbon nanotubes (MWCNTs) exhibit unique structural, electrical, mechanical, electrochemical, and chemical properties [1]. Moreover, the possibility of modifying their surface properties through different methods has stimulated increasing interest in their application as components in biosensors. In this sense, it is possible to employ carbon nanotubes as support to immobilize enzymes.
