Due to their extremely small size, single walled carbon nanotubes (SWCNTs) provide a promising framework for building single molecule electronic devices. We have developed a procedure to controllably form single carboxyl groups on a CNT's sidewall . By limiting the chemically sensitive region of a nanostructure to a single binding site, single molecule bonding dynamics become visible. Discrete changes in the circuit conductance reveal chemical processes happening in real-time and allow SWNT sidewalls to be deterministically broken, reformed, and conjugated to target species, creating new possibilities for chemical sensing and molecular electronics.
