Abstract

A photo-cleavable compound for delivery and release of a biologically active substance to selected target cells; the compound includes a binding partner for a specific cell-surface receptor of those target cells, the biologically active substance to be delivered, and a photo-cleavable bridge between the binding partner and the biologically active substance. When the compound is exposed to a heterogeneous population of target and non-target cells, it binds selectively to the receptors on the surface of the target cells. Exposing the compound to light of selected wave length cleaves it, yielding the active substance.
