 Black silicon is a synthetic nanomaterial that contains high aspect ratio nanoprotrusions on its surface, produced through a simple reactive-ion etching technique for use in photovoltaic applications. Surfaces with high […]

This is the first reported example of a naturally existing surface with a physical structure that exhibits such effective bactericidal properties. Cicada wing nanopillars are extremely effective at killing Pseudomonas aeruginosa cells; the wing surface was able to kill individual cells within approximately 3 min. This bactericidal ability of the wing surface is primarily a physico-mechanical effect, […]

Natural superhydrophobic surfaces are often thought to have antibiofouling potential due to their self-cleaning properties. However, when […]

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 […]
