ScFv applications in cancer diagnosis or therapy. Specific scFvs have been used for diagnosis when coupled with: (A) radioisotopes, (B) contrast agents, (C) fluorescent molecules, (D) biotin, and (E) scFvs conjugated to liposomes loaded with contrast agents. Specific scFvs have also been used with therapeutic purposes for the delivery and/or release of several molecules, such as: (H) peptides, (I) toxins, (J) proteins, (K) plasmid-loaded liposomes, (L) peptide-loaded liposomes, and (M) scFvs conjugated to liposomes loaded with chemotherapy agents.
