Multicomponent complex for use with substrate

摘要

Compositions and methods for use with substrates which are useful in the sustained delivery of bioeffecting agents are described. The compositions of the invention include a multicomponent complex which attaches a bioeffecting agent to a substrate with an anchor provided by a linker compound which also forms a cleavable linkage so that the bioeffecting agent's release into the area surrounding the substrate occurs in a sustained manner over an extended period of time. The methods of the invention involve providing a bioeffecting composition on the surface of a substrate so that a bioeffecting agent may be released in a sustained manner over time.
