Estimating the term…
The invention relates to an apparatus and a method for determining an analyte in a fluid. Provided in the device is a stirring zone formed in an optionally microfluidic three-dimensional structure, into which stirring zone a sample of the fluid can be introduced and in which there is a stirring device which can be operated in a contactless manner and is optionally designed as a microstirrer, the stirring device being configured so as to stir the sample of fluid introduced into the stirring zone and being loaded with at least one reagent which reacts with the analyte. The invention also provides a stirring device which can be operated in a contactless manner and is optionally designed as a microstirrer, the stirring device being loaded with the at least one reagent which reacts with the analyte.
An apparatus for determining an analyte in a fluid, comprising a stirring zone formed in a three-dimensional structure, into which stirring zone a sample of the fluid can be introduced and in which there is a stirring device which can be operated in a contactless manner, said stirring device being configured so as to stir the sample of fluid introduced into the stirring zone and being loaded with at least one reagent which reacts with the analyte, wherein the stirring device is a magnetic stirring device comprising one or more magnetic strip sections which form stirring elements, and wherein the at least one reagent is partially detachable from the stirring device during stirring the sample.
A stirring device which can be operated in a contactless manner, being loaded with at least one reagent which reacts with an analyte, wherein said stirring device is designed as a magnetic stirring device comprising one or more magnetic strip sections which form stirring elements, and wherein the at least one reagent is partially detachable from the stirring device during stirring of a sample of fluid.
