Abstract

Following a study on the feasibility of resonance energy transfer (RET) from carboxylated nanospheres with an incorporated phosphorescent donor to a cationic polyelectrolyte/acceptor aggregate on their surface, a novel scheme for homogeneous assays is presented that is based on RET from phosphorescent biotinylated nanospheres to fluorescently labeled streptavidin (SA). The phosphorescent ...
