Clean yourself

Self-cleaning solar panels and windows might soon be possible thanks to nanotechnology developed at New Tel Aviv University. Writing in Nature Nanotechnology, Ehud Gazit and colleagues describe a way to assemble peptides so that they form a kind of molecular forest on the surface of a substrate. These "peptide forests" would repel dust and water, making them potentially a perfect self-cleansing coating for windows and solar panels. The team has already been approached to develop its coating technology commercially. But, The Alchemist is curious as to how transparent a peptide coating might be...
