Tiny patterns carved in gold have demonstrated the potential of an enzyme ink for nanoscale manufacturing.

Researchers from Duke University in Durham, North Carolina say that the patterns are a proof of principle that enzymes, biological catalysts used widely in industry, can be used to create nanoscale structures.



“We wanted to see if we could steal functionality from biology to make the complex structures we need,” says research leader and biomedical engineer Ashutosh Chilkoti. “In an afternoon, we inexpensively created a nanostructure that would have taken weeks to develop using expensive, traditional methods of etching circuits into chips.”
