Microspheres with fluorescent and magnetic properties

摘要

A microsphere (10) comprising: - a core microsphere (46), - a magnetic material (44) coupled to a surface of the core microsphere (46), and- a layer (48) of polymer surrounding the magnetic material ( 44) and the core microsphere (46) .caracterizada porqueun 50% or less of the surface of the core microsphere (46) is covered by the magnetic material (44) and porqueel magnetic material comprises particles or aggregates of particles having a size of 10 nm to 1000 nm.
