A new anticancer drug-delivery system engineered by two University of Nebraska scientists may advance chemotherapy research and reduce the side effects of chemotherapy.
The process begins in Leslie-Pelecky’s laboratory with the construction of magnetic iron-oxide particles nearly a billionth of a meter (nanometer) in size. The iron-oxide is surrounded by a drug-binding layer and a polymer shell that enables the particles to be dispersed in the blood. A tiny magnet placed at the cancer site attracts the iron oxide in the nanoparticles, so the toxic drugs make a bee line for the tumor, minimizing their exposure to healthy cells.
