Abstract

original image

Twelve metal ions are analyzed by a microchip that was developed for high-performance recognition and analysis. The microchip enhances fluorescence at multiple channels and improves the discriminability of multi-analyte testing. The facile fabrication of the microchip and insights into sensing efficiency will be of great importance for the development of advanced discriminant analysis for complex analytes.
