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.
