The receptor and cell micro array-based chips have shown widely promising applications in many fields such as biomedicine, environment, and food. Receptor and cell micro array-based chips have become a hot research topic in the field of biomedical sensing technology. This project will focus on the development of novel bitter receptor and cell micro array-based biomimetic taste biosensors on the basis of our previous research work. In order to address some urgent problems of biomimetic sensing technology, this project will study the production of bitter receptors and cells based on cell-free protein expression systems and molecular cloning. To construct highly ordered specific bitter receptor- and cell-based micro arrays, the coupling of bitter receptors and cells with sensing chips will be investigated based on DNA hybridization encoding technology. The diffenential evolution algorithm will be employed to study the high-throughput and fast response profiles as well as sensing mechanisms of biomimetic taste biosensors. The biomimetic taste biosensors can not only be used in the research of taste transduction mechanisms, but also be applied in the high-throughput and real-time detection of specific bitter substances. The scientific significance of this project is to provide new theoretical foundation and application basis for the receptor and cell micro array-based biomimetic sensing technology. There is no reports on the biomimetic taste biosensors similar to that proposed in this project. Therefore, this project shows significant innovation and independent intellectual property rights. This project has great potential to achieve distinct progress and breakthrough in the key problems of biomimetic sensing technology as well as in the research of taste transduction mechanisms.
