Abstract

The invention relates to a composite micro-nano structure array on a high light-transmission substrate and a method and application of the same. The invention is characterized in that micro-nano structure arrays of light guide materials on the high light-transmission substrate are taken as supporting structures of fluorescent conjugated polymers for detection. The method comprises: firstly, preparing the micro-nano structure arrays and secondary structure arrays of the light guide materials on the high light-transmission material substrate such as quartz and the like; and secondly, coating the fluorescent conjugated polymers which are sensitive to specified analyte on the surface of the nano structure substrate to form the composite micro-nano structure array which is used for detecting an object. The invention takes the micro-nano structure arrays of different light guide materials as adhesive substrates of the fluorescent conjugated polymers and utilizes the advantages of micro-nanostructures such as large specific surface area, evanescent wave effect, micro resonant cavity action and the like to improve the sensitivity of detection and the signal intensity, prolong the servicelife and improve the reutilization property. The composite micro-nano structure array on the high light-transmission substrate can be applied to the detection of the specificity and high sensitivity of solid, liquid and gas molecules.
