英文摘要： To solve the traditional chemical sensor responsive limitation on multi-analyate testing and the sensor array chip limitation on the high cost of combinatorial chemistry and organic syntheses, we introduce the multi-stopband photonic crystal array into the sensor array chip. The different stopband photonic crystals will enhance the sensor response fluorescence intensity at different certain wavelength which will magnify the response and difference. With one traditional and regular sensor compound, the multi-stopband photonic crystal chip could perform complex multi-analyate discrimination and recognizing. Utilizing ink-jet print technique, we will fabricate the photonic crystal chip with micro-pixel. The accurate control of the emulsion droplet will be operated and studied to produce the exactly same and repeatable pixel of the analytical grade chip. Ink-jet print multi-stopband photonic crystal microchip fabrication has the advantages on sensitive, high performance multi-analyate test; easy, fast chip processing; high-density chip and high throughput screening or analysis. It will open the new strategy to promote or improve sensors properties by using the nanotechnology but without chemical changing. The ink-jet print microchip strips will be an easy, low cost and general-purpose way for the multi-analyate high
