Colin Nuckolls is a Professor of Chemistry in the Department of Chemistry at Columbia University. His research focuses on integrating reaction chemistry into electrical devices. He is a founding member of the Columbia University Nanoscience Center. Amongst other awards, he is a recipient of a Sloan Research Fellowship, a Beckman Young Investigator Award, a 2008 ACS Arthur C. Cope Scholar Award, and the 2009 ACS Baekeland Award.
In the paper “Translocation of Single-Stranded DNA through Single-Walled Carbon Nanotubes,” recently published in Science, we report the fabrication of devices in which one single-walled carbon nanotube spans a barrier between two fluid reservoirs, enabling direct electrical measurement of ion transport through the tube. A fraction of the tubes pass anomalously high ionic currents. Electrophoretic transport of small single-stranded DNA oligomers through these tubes is marked by large transient increases in ion current and was confirmed by polymerase chain reaction analysis. Each current pulse contains about 107 charges, an enormous amplification of the translocated charge. Carbon nanotubes simplify the construction of nanopores, permit new types of electrical measurements, and may open avenues for control of DNA translocation.
