Abstract
The invention presents a stationary phase for detecting at least one specific analyte in a mixture. The stationary phase includes a solid phase divided into a plurality of zones for transporting liquid by capillary force. The solid phase includes at least one first zone suitable for receiving a liquid sample, a second zone on which a receptor is immobilized, wherein the receptor is suitable for binding to a ligand, and a third zone on which quantum dots are immobilized, function as FRET donors and are linked to at least one suitable FRET acceptor via at least one oligonucleotide linker. The stationary phase exhibits improved detection sensitivity and allows simultaneous and multiparametric detection of a wide variety of analytes. The invention proposes uses of the stationary phase and also presents a method for detecting at least one specific analyte in a mixture.
