NASA uses ‘extremophile’ microbes to grow nanostructures

NASA scientists have invented a biological method to make ultra-small structures that could be used to produce electronics 10 to 100 times smaller than today’s components. As part of their new method, scientists use modified proteins from ‘extremophile’ microbes that live in near-boiling, acidic hot springs to grow mesh-like structures so small that an electron microscope is needed to see them.
“Our innovation takes advantage of the innate ability of proteins to form into ordered structures and for us to use genetic engineering to change nature’s plans, transforming these structures into something useful,” said one of the project’s lead researchers.
