Abstract: An apparatus for electrochemically detecting and/or measuring an analyte (e.g. melatonin) in a fluid sample has a dry porous carrier that permits flow of a fluid sample by capillary action to biosensor (e.g. an analyte detection electrode set). The biosensor has a working electrode and a counter electrode disposed across the carrier in a non-parallel direction in relation to a direction of fluid flow such that the fluid sample crosses at least the working electrode embedded in the carrier.

Abstract: The invention relates to an optoelectronic measurement method for determining a position, particularly an angle or a length, of a code carrier (10) that carries a position code (11) and is movable relative to a detector element (30) with a degree of freedom, particularly in a rotary or translational fashion. The detector element (30) has at least one line in the longitudinal direction comprising a plurality of light-sensitive receiving regions (31) disposed in a linear fashion. In the course of the positional measurement method, a projection is produced of part of the position code (11) on the detector element (30) that is dependent on the position of the code carrier (10); said projection is produced by at least an emission of optical radiation onto the code carrier (10) using a laser diode (20) having an emitter edge (21), and said projection is detected by the detector element (30). The position of the code carrier (10) relative to the detector element (30) is derived from the projection.

Abstract: A nucleotide triphosphate (NTP) participates in a phosphorylation reaction, wherein a phosphate group is transferred from the NTP to a substrate by a kinase. Provision in a kinase reaction of a NTP whose gamma phosphate is conjugated to an electroactive label results in the transfer of the gamma phosphate-electroactive label conjugate from the NTP to the substrate. The electroactive label is an organic moiety such as a quinone or a nitroheterocycle, or is a metallocene such as a ferrocene or a cobaltocene. Upon transfer of the gamma phosphate-electroactive label conjugate to an electrode-bound substrate by a kinase, the phosphorylation event is detected electrochemically by cyclic voltammetry. Phosphorylation can also be detected by mass spectrometry of a substrate carrying the electroactive label-conjugated gamma phosphate.
