Nanoparticles Targeted to Brain Tumors
Glioblastoma multiforme is among the most aggressive and difficult cancers to treat. Now, researchers at Penn State University have shown that a lipid-based nanoparticle, designed to bind to a specific receptor found on malignant brain cells but not healthy ones, improves the potency of a common anticancer drug and slows significantly the growth of glioblastoma in mice.
