英文摘要: Current multi-analytes chips are limited with requiring numbers of sensors, complex synthesis and compound screen. It is expected to develop new principles and techniques to achieve high-performance multi-analytes testing with facile sensors.Utilizing interconversion of photochromic materials, we design and perform multiplex metal ions sensor array containing only one spirooxazine molecule as selective and cross-reactive sensing element. Based on the multi-state of photochromic sensor coordination in various light or stimulation irradiations, it can offer abundant chemical information of the sensing process and be capable of discriminating among vast different analytes. With theoretical and experimental analysis, we could confirm and contribute the totally new method for the multi-analyte sensor chip design. The further study will perform electro-, magnet-, thermo- and pH stimulating materials to the high-throughput sensing chip. Utilizing abundant chemical information in interconversion, the stimulative response sensor chip will carry out the high-performance multi-analytes detection by one sensor. The facile stimulative multi-state sensor microchip will open new opportunities for the development of advanced discriminant analysis for complex analytes.
