Publication number: 20070196813Abstract: In a method for preparing a blood sample for subsequent processing in a mass spectrometry laboratory, substances of interest are extracted from whole blood, blood plasma or blood serum immediately after the blood sample has been taken from a subject. The extraction is carried out by means of reversible immobilization on a surface, for example, the surface of a blood extraction vessel. Only the extracted substances of interest are sent in the immobilized state to the mass spectrometry laboratory.Type: ApplicationFiled: January 24, 2007Publication date: August 23, 2007Applicant: Bruker Daltonik GMBHInventors: Jochen Franzen, Hans-Jakob Baum, Karsten Michelmann

Publication number: 20040235028Abstract: The invention relates to the detection of the binding of analyte molecules, for example biopolymer molecules, to immobilized capture substance molecules. The invention consists in using semiconductor wafers (chips) with electrical circuits in spatial proximity to a surface area coated with capture substance molecules and loading the binding of the analyte molecules to the capture substance molecules with co-bound electrically conductive nanoparticles so that the nanoparticles can act upon the electrical circuits either through changes in the electrical stray capacitance or by generating electric currents, thus making the binding of the analyte molecules electronically detectable.Type: ApplicationFiled: April 14, 2004Publication date: November 25, 2004Applicant: Bruker Daltonik GMBHInventors: Jochen Franzen, Hans-Jakob Baum
