Patent ID: 11724246

Abstract:
A method of preparing a magnetic particle having a polymer matrix (P) and at least one magnetic core (M), preferably at least two magnetic cores (M), wherein the polymer matrix (P) comprises at least one hypercrosslinked polymer, wherein the method comprises (i) providing at least one magnetic core (M), preferably at least two magnetic cores (M), (ii) providing polymer precursor molecules, (iii) polymerizing the polymer precursor molecules according to (ii) in the presence of the at least one magnetic core (M), thereby forming a particle comprising the at least one magnetic core (M) is disclosed. Further, particles obtained or obtainable by this method as well as to the use of these particles are disclosed. In a further aspect, a method for determining at least one analyte in a fluid sample having the step of contacting of the magnetic particle with a fluid sample having or suspected of having the at least one analyte is disclosed.
