Folate and bombesin molecules were conjugated at the surface of the dendrimers for simultaneous targeting of folate receptors and gastrin‐releasing peptide receptors (overexpressed in breast cancer cells) (Figure7).[36] In vitro studies indicated selective uptake of 177Lu‐dendrimer‐AuNP‐folate‐bombesin in T47D cancer cells that was inhibited in the presence of competing free bombesin or folic acid. This evidence concerns the gene GRP and cancer.
