Abstract: 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.

Abstract: 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.

Abstract: A sampling device for inspection vehicles equipped with an environmental inspection system, the system comprising an analyzer having a receiving head (21), to which the substances to be examined are supplied by means of a movable collecting body (4) having a ground-engageable contact surface. The collecting body is formed by a rope-like material (4) which is wound up on a supply drum (2) and passed between two rollers (10, 11) arranged at a certain distance therefrom. By displacing the material (4) in its longitudinal direction, the material can be moved into a first position in which an end section (41) of the material hangs down and contacts the ground (42), and a second position in which the end section (41), which had been in contact with the ground (42), is positioned opposite the receiving head (21). Consumed end portions (41) can be cut off by means of a separating device.
