Arrangement of Ferritin Molecules on a Gold Disk Array Fabricated on Highly Ordered Anodic Porous Alumina Substrate

An ordered array of ferritin, in which the arrangement of ferritin coincided with the arrangement of Au disks, was prepared on Au nanodisk arrays fabricated on a highly ordered anodic porous alumina substrate. Selective adsorption of ferritin onto the Au disk by controlling the modification time and ferritin concentration in the modification solution was confirmed by scanning electron microscopy.
