摘要：
A 2D material/metal hybrid plasmonic sensor is demonstrated by direct integration of graphene layer on gold-coated optical fiber. Both linear response to wide range ssDNA concentration from 1 x 10(-12) to 10 x 10(-6)m and low detection limit of 1 x 10(-12)m are achieved. The resulting hybrid plasmonic sensor shows prospects of highly sensitive, highly integrated, and flexible sensing at fiber-optic length scale.
