FIELD: medicine.SUBSTANCE: group of inventions refers to medicine, namely laboratory diagnostics and can be used for performing thecluster analysis. The analysis procedure involves the stages as follows: a) providing a suspension of superparamagnetic particles in a liquid to be analysed with the superparamagnetic particles coated with a biologically active agent; b) enabling the particles forming particle clusters with analytes found in the liquid; c) using a rotating magnetic field (B) with an angular frequency ensuring the magnetic field rotation only of the clusters having a size smaller or equal to a pre-set size, and d) detecting the rotating clusters. What is also presented is a device for performing the cluster analysis.EFFECT: group of inventions provides detecting the selectively activated clusters thereby increasing the analysis sensitivity.9 cl, 8 dwg |
