Abstract

See full text

A method for detecting at least one analyte (110) in a sample (112) is disclosed. The method comprises the following steps:

    a) providing at least one sample (112) having at least one analyte (110);b) incubating the sample (112) with microparticles (118) having at least one surface (120) whereby the analyte (110) is adsorbed on the surface (120) of the microparticles (118) and an analyte-microparticle-complex (122) is formed;c) providing at least one fiber sheet material (128) having at least one tip (130) and contacting the tip (130) of the fiber sheet material (128) to the sample (112) comprising the analyte-microparticle-complex (122), whereby at least the analyte-microparticle-complex (122) is sucked into the tip (130) of the fiber sheet material (128);d) contacting the tip (130) of the fiber sheet material (128) to a port of an analytical device;e) adding an extracting solvent (138) to the fiber sheet material (128) and applying an electrical voltage to the fiber sheet material (128) whereby ions of the analyte (110) are generated and are expelled from the tip (130) of the fiber sheet material (128); andf) detecting the at least one analyte (110) with the analytical device (134).
