For the use of magnetite as a tracer to estimate the biological fate of microspheres after injection, albumin microspheres containing magnetite were injected i.v. into mice; then they were examined for their biodistribution along with an in vitro test. Magnetite recollected from the homogenates of mice organs with a magnet was assayed by atomic absorption spectrophotometry. © 1988.
