Photoresistivity and optical switching of graphene with DNA lattices
چکیده انگلیسی

We present the photon induced conductivity of 2D DNA lattices with and without graphene and demonstrate the switching current responses controlled by light irradiation. The conductivity in the DNA lattices with protein streptavidin controlled by blue and white lights shows significant enhancement with the addition of graphene. An optical pulse response of a graphene immobilized DNA lattice is encouraging and may lead to various bio-sensing applications such as immunological assays, DNA forensics, and toxin detection.


► The photon induced conductivity of DNA lattices with graphene was presented.
► The switching current response controlled by light irradiation was discussed.
► An Optical response of a graphene with DNA leads to biosensing applications.
