Protein detection is demonstrated by using a fluorescence graphene aptasensor formed on the inner wall of a micro cylinder (micro-roll). The graphene aptasensor is incorporated with self-foldable flexible films, leading to a three-dimensional (3D) sensing system. Since the formation of the micro-roll avoids any cytotoxic processes, the micro-roll can be used as a container to encapsulate living cells. The performance of the micro-roll graphene aptasensor is successfully confirmed while multiple cells are simultaneously encapsulated.
