The authors report a graphene-polymer hybrid nanostructure-based bioenergy storage device to turn on and off bio-motor activity in real-time. In this strategy, graphene was functionalized with amine groups and utilized as a transparent electrode supporting the motility of bio-motors. Conducting polymer patterns doped with ATP were fabricated on the graphene and utilized for the fast release of ATP by elec. stimuli through the graphene. The controlled release of bio-motor fuel, ATP, allowed the authors to control the actin filament transportation propelled by the bio-motor in real-time. This strategy should enable the integrated nanodevices for the real-time control of biological motors, which can be a significant stepping stone toward hybrid nanomech systems based on motor proteins on SciFinder(R).
