Formation of a graphene oxide-DNA duplex-based logic gate and sensor mediated by RecA-ssDNA nucleoprotein filaments.

A conceptually new class of DNA logic gate and biosensor using the complex of a graphene oxide-DNA duplex as a scaffold was reported, achieved by means of formation of the triple-stranded DNA structure mediated by Recombinational protein A (RecA)-ssDNA nucleoprotein filaments with graphene oxide.
