Floating Nanosheets Could Be the Plywood of Nanotechnology

A synthetic, free-floating nanosheet just two molecules thick may provide the perfect substrate for creating future electronic devices.

The biologically inspired sheet is made of polymers, or long molecules with repeating units, that mimic the precision and order seen in proteins and crystal structures. But these synthetic sheets are made of molecular building blocks that are more durable than their natural counterparts.

“We’re making molecular plywood — a flat piece of building material that you can build nanoscale structures with,” said chemist Ronald Zuckermann of Lawrence Berkeley National Laboratory, coauthor of a study April 11 in Nature Materials. “This study will open people’s eyes and make them talk about proteins and plastics in the same sentence.”

Zuckermann’s team made the discovery by stumbling upon a particular sequence of repeating units that formed perfectly aligned two-dimensional crystals.
