Research output: Contribution to conferencePaper


At the early stages of the photosynthetic process of purple photosynthetic bacteria, light-harvesting protein complexes, called LH1 and LH2, absorb solar energy and transfer it to the reaction center (RC), where upon the absorbed energy is efficiently converted into electrochemical energy in the photosynthetic membrane. We are interested in the rapid and efficient energy transfer between LH1 and RC proteins and have been aiming to construct an artificial solar energy device based on a natural solar energy conversion system such as the core complex. In this presentation, we demonstrate the self-assembly monolayer (SAM), AFM imaging and photocurrent responses of these proteins on the solid surface for providing insight into the structure and function of these proteins as well as for development of the devices.
