Nanoslit Confined DNA at Low Ionic Strengths.

ACS Macro Lett

Department of Chemistry and Interdisciplinary Program of Integrated Biotechnology, Sogang University, Seoul, Republic of Korea.

Published: September 2014

AI Article Synopsis

Article Abstract

We present nanoslit confined DNA conformations at very low ionic strengths and a theory to explain most measurements for single DNA molecule size under strong nanoslit confinement. Very low ionic strength conditions not only increase the DNA persistence length dramatically, but also cause DNA molecules to swell to the extent that the effective diameter of DNA becomes larger than the nanoslit height. By accounting for these effects, our results and theory provide a reasonable clue for a current controversy regarding the dependence of the DNA conformation on slit height (), persistence length (), and effective diameter ().
