Gold nanoparticles kill cancer without chemo

+

Feb 09, 2013· Study: Gold nanoparticles kill cancer without chemo. Lymphoma can be starved to death by depriving it of what appears to be a favorite food: highdensity lipoprotein (HDL) cholesterol. A new nanoparticle appears to the cancerous lymphoma cell like a preferred meal of natural HDL. When the particle engages the cell, it plugs it up and blocks ...
