摘要:
Complex of an anti-cocaine aptamer and the dye diethylthiotricarbocyanine behaves as a calorimetric sensor with attenuation in absorbance at 760 nm for cocaine in the concentration range of 2-5000 μM. Mechanistic studies indicate an intermolecular displacement of the dye as the mechanism of action of the sensor. As the dye is insoluble in buffer, cocaine binding can be detected as displaced dye precipitates and supernatant decolorizes.

摘要:
Cross-reactive arrays on encoded beads are used to correlate ‘fingerprints’ of urine, serum and other biological liquids to disease states. Fluorescent hydrophobic sensors are based on nucleic acid three-way junctions, and beads may be encoded by size (could be registered by light scattering) and fluorescence in combination with flow cytometry analysis, also known as suspension array technology (SAT).
