Abstract

A procedure to fabricate tunable surface morphology of self-assembled graphene nanoplatelets or silver nanoparticles on a shrink polymer substrate in this paper demonstrates controllable features different from conventional graphene and silver nanoparticle composites. Subsequently, a graphene biosensor integrated with silver nanoparticles is developed using roll-to-roll fabrication process without lithography. This biosensor with a higher sensitivity and a lower detection limit indicates that this simple low-cost process has many potential applications to label-free, ultra-sensitive, and molecule-specific detections. The shrink properties of polymer composites promise potential applications to biomedical and chemical sensing.
