A facile, controllable fabrication of polystyrene/graphene core-shell microspheres and its application in high-performance electrocatalysis.

Polystyrene/graphene (PS/GP) core-shell microspheres which are demonstrated to be highly sensitive for dopamine (DA) detection with excellent morphology were prepared via electrostatic interactions and π-π accumulation. This interesting discovery is practical to utilise compared to traditional biotechniques and surface functionalization methods.
