Methods for delivering ligands to a cell by using light to activate fluorescent ligands causing their release from endosomes. The instant methods thus increasing the efficiency of ligands, e.g. in vitro or at localized sites within a subject. The invention provides for the release of ligands by shining a light source on a cell to promote release of ligands into the cell where they can effect their function.
