| 摘要 |
A method for preparing an analyte-containing solution, which is compatible with surface-tension-directed liquid droplet manipulation and solid-phase affinity-based assays, is disclosed. The method comprises providing an affinity capture surface comprising a substrate surface having a plurality of first and second surface modifiers associated therewith, wherein the first and second surface modifiers render the affinity capture surface wettable and resistant to non-specific protein adsorption, and wherein the second surface modifiers are capable of selectively retaining an analyte, contacting the affinity capture surface with the analyte to form analyte/surface modifier complexes between the analyte and the second surface modifiers, and cleaving the first and second surface modifiers to release terminal portions of the first and second surface modifiers and the analyte into a solution in contact with the affinity capture surface, thereby yielding the analyte-containing solution and generating a hydrophobic surface. Novel affinity capture surfaces and methods for preparing the same are also disclosed.
