Product with magnetic beads, which have a functionalized surface

摘要

Product, with magnetic beads, which have a functionalized surface and can be produced in the following manner:a) providing of magnetic particles, short beads, with a particle size in the nano - and / or micro - region, i.e, one or more nm or μm, and on whose surfaces applied functional group, such as, for example, amino groups,b) reacting the beads in a branching reagent, such as, for example, methyl acrylate containing organic solvent,c) separating the beads from the organic solvent and washing of the beads with an organic solvent,d) reacting the beads with a connector, such as, for example, ethylenediamine, organic liquid containing,e) separation of the beads from the organic liquid and washing the beads,f) n - times repeating the steps b) to e)g) suspending of the beads in a solution, the at least one for the derivatization suitable substance andh) separation and washing of the beads and providing the derivatized beads in water or..
