    摘要: The toner includes emulsion aggregation toner particles having a core and a shell. The core includes binder including a first non-crosslinked styrene acrylate polymer and a crosslinked styrene acrylate polymer, at least one colorant, at least one wax, and aluminized silica. The shell includes a second non-crosslinked styrene acrylate polymer that is preferably the same as the non-crosslinked styrene acrylate polymer of the core. The aluminized silica is advantageously used as a coagulant in the emulsion aggregation formation of the toner. A developer containing the toner and a method of forming an image using the toner are also described.

    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.
