A facile one-pot route to poly(carboxybetaine acrylamide) functionalized SWCNTs

Chem Commun (Camb). 2013 Aug 4;49(60):6734-6. doi: 10.1039/c3cc43361g.

Abstract

An unprecedented one-pot procedure employing a cyclopentadienyl functionalized RAFT agent allowed the grafting of poly(carboxybetaine acrylamide) - a highly functional and biocompatible polymer - from the surface of pristine SWCNTs. The pendant carboxylic acid groups of the surface grafted polymer were further conjugated with single-stranded (ss)-DNA, which was successfully hybridized with a Cy5 labelled complementary DNA strand.
