Underwater superoleophobic-oleophilic chips were developed to achieve oil extracting from aqueous solution and oil-droplet con-densing to preset microwell.The double-hierarchical(extracting-condensing)enrichment strategy drastically improves the sensitivi-ty for organic contaminants or components,whose signal amplification approaches 459.7 times that of primary solution and 25.9 times that of single condensing enrichment strategy.Low to femtomolar limit of detection(2.6×10^(-15)mol/L)sensitivity and 6 vari-ous aflatoxins or mildewed foods identification demonstrate the significance and promotion for environment monitoring,water pu-rification,and so on. 展开更多
