Anti-bacterial surfaces inspired by cicada and dragonfly wings

Many surfaces found in nature possess sophisticated topographical structures which provide them with exceptional properties. Nano-structured surface of lotus leafs efficiently repel water, microscopic brushes of gecko fingers drastically increase the contact with surfaces, topographical structures provides for enhanced anti-reflection surface properties in insects. Self-cleaning ability of bio-surfaces enables them to prevent contamination by particles […]

Langmuir, 27(18), 11710-11721 (2011)

Magnetron sputtering techniques were used to prepare molecularly smooth titanium thin films possessing an average roughness between 0.18 nm and 0.52 nm over 5 μm × 5 μm AFM scanning areas. Films […]
