Alumina Nanotemplate  - The alumina nanotemplate is composed of porous anodized aluminum fabricated on a variety of substrates. The pores within the electrically insulating alumina are vertically oriented, with uniform pore diameters and lengths. Templates with a size of 1.5cmx1.5cm or 4" wafers can be ordered with pores having diameters from 25-250nm, lenghts of 250nm to 1000nm and with a variety of conducting electrodes at the base of the pores.
