As a consequence, albumins have emerged as a potential drug carrier and find numerous applications as theranostic agents, contrast agents, biosensors, and implants against cancer, diabetes, arthritis, and hepatitis C. The structural domains and functional groups in albumin allow the binding and capping of several inorganic nanoparticles that enhances its bioavailability, compatibility, and circulation times, with selective bioaccumulation and reduced toxicity [244,245]. This evidence concerns the gene ALB and cancer.
