Modulating the Light-Driven Conductivity in Biosystem

Biosystems has been proved powerful for use in nanotechnology because of its predictable nanometer-sized structures. One important example is that we can use biosystems to develop the new two- and three-dimensional nanomachines and nanocircuits. To achieve this goal, people hope to control the conductivity properties of system. In this regard, light-regulated circumstances come into play. Photon-induced charge transport can regulate the conductivity properties of system. The role of photoresponse of π electrons of biosystems in light-driven conductivity theoretically studied. We have varied the intensity and frequency of light and investigated their effect on the charge transport properties of system. Therefore, one can modulate the conductivity properties of system via the directly modulation of the light.
