    摘要: A method of forming polymeric microspheres for biomedical applications includes forming polymeric microspheres by an emulsion/aggregation process from a precursor monomer species, and treating the polymeric microspheres to attach a biomedical functional material to the polymeric microspheres, where the polymeric microspheres have an average particle diameter of from about 1 to about 15 microns with a narrow particle geometric size distribution. The biomedical functional material may be, for example, a radioactive material, a radioactive precursor material, a bioactive agent, or a ligand.

    摘要: A toner process comprising aggregating or coagulating a latex emulsion comprising a resin, a colorant and wax particles using an amount of polymetal ion coagulant to provide core particles; heating the core particles to provide micron size aggregates; optionally adding a second resin emulsion; adding a sequestering or complexing component and a base to remove the polymetal ion in a controlled manner; further heating the mixture to provide toner particles; and optionally, isolating the toner particles.
