GRP and breast carcinoma: 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.
