Abstract: A microfluidic blood serum generator having a first port and a second port, between which there is formed a microfluidic structure, wherein the microfluidic structure has a supply duct communicating with the first port, a clotting region into which the supply duct discharges, and a discharge duct which communicates with the second port and into which the clotting region transitions, wherein the first port is designed to introduce a blood sample at a first pressure and the second port is designed to apply a second pressure that is lower than the first pressure, wherein the clotting region is formed by a single, coherent cavity, and wherein a barrier for retaining a clotted blood sample is arranged in the transition from the clotting region to the discharge duct. A method for separating off blood serum from a blood sample using a blood serum generator of this kind.

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.
