Abstract
A coated magnetic particle comprising an optionally porous magnetic polymer particle of a matrix polymer, said polymer particle having on a surface and/or in the pores thereof superparamagnetic crystals, said coated particle having a coat formed of a coating polymer, wherein said coated magnetic particle is essentially non-autofluorescent.
Claims31
A coated magnetic particle comprising an optionally porous magnetic polymer particle of a matrix polymer, said polymer particle having on a surface and/or in the pores thereof superparamagnetic crystals, said coated particle having a coefficient of variation (CV) of less than 10% and having a coat formed of a coating polymer, wherein said coated magnetic particle is essentially non-autofluorescent.
An optionally porous magnetic polymer particle comprising a matrix polymer, with disposed on the surface and/or in the pores thereof superparamagnetic crystals, said matrix polymer being essentially free of conjugated delocalized electron systems and optionally being surface functionalised with groups selected from sulphonic acid, carboxylic acid, amine, and epoxy groups, said particle being essentially non-autofluorescent.
