Abstract

Abstract : We focused on a cicada wing which has superhydrophobic surface, antireflection to the light, unique tribology, and antibacterial property. From the SEM view, circular truncated cones in nanoscale were widely spread with regularly. It was just like nanopillar array. After the signature pattern was analyzed, we mimicked its structure composed of Si. Si nanostructure was fabricated mainly by wet process to decrease the cost but its dimension was controllable. We reported antibacterial property of the structure. Fabricated Si nanopillar array showed antibacterial property to E. Coli .
