Another study by that group demonstrated that a combination of transferrin-conjugated polyethylene glycol (TF-PEG) liposomes encapsulating sodium borocaptate and Iomeprol with intratumoral convection-enhanced delivery (CED) enabled not only precise and potent targeting of boron to the tumor tissue, but also tracing of boron administered intratumorally using real-time computed tomography [20]. The gene discussed is TF; the disease is neoplasm.
