Abstract

By using DNA linkers, we are able to conjugate self-crosslinked SWNTs which could be detected upon hybridization with a DNA immobilized resonator. The DNA immobilized resonator is able to detect SWNTs with a detection limit of 10 ng ml−1 which was 2–3 orders of magnitude smaller than the reported SWNT toxicity concentration.
