Light driven open/close operation of an azobenzene-modified DNA nano-pincette.

Abstract

A photoresponsive DNA nano-pincette was constructed by using azobenzene-modified DNA as materials. When the azobenzene-modified part hybridizes with its complementary sequence on the pincette, the duplex formation closes it. On the contrary, the pincette is opened after the formed duplex dissociates. Based on reversible photoswitching of this DNA… (More)
