Anti-reflection surfaces
Nanofabrication- from the lab to the fab
Commercial systems for large-area sub-micron patterning of surfaces, such as mask-based photolithography are expensive. In contrast interference lithography is a low cost maskless patterning approach capable of large areas (> m2), reproducibility and high throughput.

Anti-reflection
Anti-reflection surfaces on solar cells can be created by nanotexturing to enhance the amount of light captured and converted into electricity.

Anti-glare
Glare can make it difficult to see the screens on portable electronic devices. Luckily nature has offered the perfect anti-glare solution in the form of the microstructures found on the surface of insect eyes, such as those found on the mosquito eye shown above.

Smart windows
Smart windows and building energy efficiency- US buildings account for 40% of the country’s energy usage. Smart windows can use nanostructures to change the window from being transparent to opaque to control the amount of light/heat entering the room.

Self-cleaning surfaces
Self-cleaning surfaces are highly hydrophobic surfaces that can be created using nanostructures. Liquid cannot stick to the surface and tends to roll off. An example of a highly hydrophobic surface in nature is the lotus leaf.
