One of the world’s strongest structures could be one of its smallest: Collaborators from University of Connecticut, Columbia University, and Brookhaven National Lab have developed a new nanomaterial composed of DNA strands coated in flawless glass. At proportionally four times stronger and five times lighter than steel, the minuscule latticework structures could provide a template for a new wave of extremely durable and lightweight vehicles, body armor, and countless other products.
As detailed recently in Cell Reports Physical Science, the team first connected multiple portions of self-assembling DNA to form a nanostructure framework akin to a building’s support beams. They then coated the enjoined DNA strands with a glass-like material only a few hundred atoms thick, leaving relatively large empty spaces akin to rooms in a house. These spaces allowed the resulting nanomaterial to remain extremely lightweight, while the glass reinforced its durability.
