英文摘要： Bacteriorhodopsin (bR) has attracted much interest in bioelectronics because of its desirable photonic properties and long-term stabilities along with the ability to maintain its biological activity when immobilized on solid supports. Bioelectronic nano-device on basis of bR can explore its applications in integrated bioelectronics device systems as nano-scaled power supply source or opto-electric sensing unit. Moreover, the study on the photonic behavior of bR units on one-dimensional nanowire is also of great importance to achieve high performance for bR-based photonic device in future. In this program, top-down micro/nano fabrication technique and bottom-up self-assembly technique are combined together to incorporate bR molecules onto single-conducting-polymer nanowire-based building blocks via a self-assembly process. The controlled self-assembly behavior of bR molecules on a single conducting polymer nanowire will be realized by the use of different dopants and the control of assembly environment. The photonic performance studies at the single nanostructure level will be able to elaborate the mechanism of the single-conducting-polymer-nanowire-based bR photonic device, and illuminate the relationship among intrinsic material properties, structures and functions of such device, which could establish fundame
