We present a method for functionalization of single-?walled carbon nanotubes (CNTs) with amine-?terminated dendrimers encapsulating catalytic nanoparticles, and demonstrate the feasibility of functionalized CNTs as efficient field-?effect transistor (FET)?-?sensing platforms. As a model system, we synthesized Pt dendrimer-?encapsulated nanoparticles (DENs) using amine-?terminated sixth-?generation poly(amidoamine) dendrimers, and functionalized CNT-?based FET channels with Pt DENs via electro-?oxidative grafting of the terminal amines of dendrimers onto the surface of CNTs. We also demonstrated spatially-?controlled surface functionalization of CNTs and subsequent modification of the functionalized CNT-?based FET channels with glutamate oxidases for efficient FET-?based sensing of glutamates. Our approach could facilitate the functionalization of CNTs with a variety of catalytic nanoparticles and biol. active materials, enabling the development of sensitive and selective FET-?based sensor devices.
