Membrane-spanning DNA nanopores with cytotoxic effect

Angew Chem Int Ed Engl. 2014 Nov 10;53(46):12466-70. doi: 10.1002/anie.201405719. Epub 2014 Oct 7.

Abstract

DNA-based cytotoxic agents: Nanopores composed of folded DNA featuring a hydrophobic belt of ethyl phosphorothioate groups insert into bilayer membranes and kill cancer cells. The mode by which the pores achieve cell killing is elucidated with confocal microscopy.

Keywords: DNA origami; cancer; cells; nanopores; nucleic acids.
