英文摘要： The use of fossil fuels in recent years has accelerated and this triggers a global energy crisis and environmental issues. Under such circumstance, biofuel cells (BFCs) based new power sources have attracted much attention due to their high energy conversion efficiency, abundant source supplies, environmental friendly properties and mild operational conditions. This project aims to construct BFCs based visual “self-powered” system, which explores new functions while takes advantage of new energy. First of all, excellent and stable BFCs would be achieved and could be combined with electrochromic device to construct self-powered electrochromic system with excellent reversibility and stability. The laws governing the combinational process will be discussed in detail. Then, an integrated self-powered fluorescence switch system based on BFCs could be obtained with the aid of fluorophores. The tuning of fluorescence would be accompanied with the electricity-generation process. Most importantly, by introducing specific effective matters, visual and recoverable biosensors could be finally developed based on the self-powered electrochromic or fluorescence switch system. Moreover, these sensors would be applied to detect real samples. This project would not only provide theoretical and experimental understandings of constructing multi-functional and sustainable self-powered system, but also initiate cross-disciplinary innovations of related fields such as biology, chemistry and energy.
