Nanotextured implant materials: blending in, not fighting back

...r blood vessel grafts, so they came out completely covered with bumps that were 100, 200 or 500 nanometers in diameter. The surface with 200-nanometer features strongly favored the adsorption and spreading of fibronectin, a protein that helps endothelial cells quickly coat the graft. Webster and Haberstro...

...'s pockets. This gave them capsules with a surface covered with folic acid molecules. What for? Many tumors have a significantly increased number of folic acid receptors on the surfaces of their cells. The folic acid on the capsules docks into these sites and is brought into the interior of the cell. Here, t...
