Abstract

A simple encapsulation technique is presented to produce highly phosphorescent, inert nanospheres that are suitable luminescent markers. It is based on the coprecipitation of phosphorescent ruthenium(II)-tris(polypyridyl) complexes and polyacrylonitrile, (PAN) derivatives from a solution in IV V-dimethylformamide. The beads precipitate in the form of very small aggregates of spherical shape and a ...
