The present invention relates to magnetic particles, wherein each particle comprises a polymer matrix and at least one magnetic core (M), wherein the polymer matrix comprises at least one crosslinked polymer and wherein the magnetic particle has a particle size in the range of from 1 to 60 micrometer. Further, the present invention relates to a method of preparing such particles, and to particles obtainable or obtained by said method. Moreover, the present invention is concerned with the use of these magnetic particles for qualitative and/or quantitative determination of at least one analyte in a fluid. Further, the present invention relates to a method for determining at least one analyte in a fluid sample comprising the contacting of a magnetic particle of the invention or a magnetic particle obtained by the method of the present invention with a fluid sample comprising or suspected to comprise the at least one analyte. |
