1. A method of forming a high aspect ratio adhesive structure, the method comprising: fabricating a porous template to have a first, second, and third plurality of pores created by successive anodization forming first, second, and third template tiers respectively, a plurality of the second plurality of pores being created within each of the first plurality of pores, and a plurality of the third plurality of pores being created within each of the second plurality of pores, wherein the porous template thus fabricated is of an integral piece having said tiers of pluralities of pores integrally formed therein; introducing a softened polymer into the template so as to conform with each of the pluralities of pores; and separating the polymer from the template as the adhesive structure, the adhesive structure replicating the first, second, and third tiers of the first, second, and third plurality of pores respectively.
