摘要: A microfluidic reactor arrangement (100) for use in detecting an analyte in a fluid sample (106) is described. The reactor arrangement is provided with a reagent providing means such that the reagent can be introduced after assembly of the reactor arrangement. The latter can be performed by introducing the reagent in the form of a solution or a dispersion and fixing it on a holding means (118) by removal of the liquid, i.e. by drying, the holding means comprising the reagent in a solid version in the detector chamber. Prior to the introduction of the reagent, components of the reactor arrangement already present, such as the sample inlet can be hydrophilised by a wetting hydrophilising technique. The invention relates to a manufacturing technique as well as to the resulting product. The invention furthermore relates to functionalizing of the reactor arrangement with a particular reagent for particular applications. The latter can be performed well after fabrication and assembly of the major reactor arrangement components.

摘要: The invention relates to a cartridge (100) and a corresponding sensor device for the detection of target components in a liquid sample. The cartridge (100) comprises a sample chamber(SC), at least two reservoirs(131, 132) that can be furnished with magnetic particles(MP, MP′), and at least two corresponding sensitive zones (121, 122) in which solved magnetic particles and/or target components can be detected. When a magnetic actuation field(B) of a given configuration is established in the sample chamber, the magnetic particles of different reservoirs migrate predominantly to different sensitive zones. Thus a mixing of magnetic particles can be avoided.
