Direct laser patterning of graphene-based biosensors

In this work we developed methods of maskless laser patterning of graphene oxide surface. By varying of laser pulses and energies we find optimal energy to make GO reduction in patterned areas. By laser reduction of graphene oxide, we made patterns which could be used for biosensors. We put aptamers on sensing structures and measured spectral properties of such structures. We showed stability of biosensor structures electric characteristics.
