LTF and cancer: Lactoferrin has also been used to improve brain imaging techniques; coated super‐paramagnetic iron oxide nanoparticles were used to enhance imaging resolution for brain tumor detection (Figures 5a and 5b).135, 136 Nanoparticles coated with lactoferrin and labeled with a far‐red fluorescent dye have also been evaluated for brain tumor imaging and showed promising results for this application.137 In addition to cancers, brain targeting via lactoferrin can also be useful for treating neural disorders such as Alzheimer's.
