Peptoid nanosheet

In nanobiotechnology, a peptoid nanosheet is a synthetic protein structure made from peptoids. Peptoid nanosheets have a thickness of about three nanometers and a length of up to 100 micrometers, meaning that they have a two-dimensional, flat shape that resembles paper on the nanoscale.

This makes them one of the thinnest known two-dimensional organic crystalline materials with an area to thickness ratio of greater than 10⁹ nm. Peptoid nanosheets were discovered in the laboratory of Dr. Ron Zuckermann at the Lawrence Berkeley National Laboratory in 2010. Due to the ability to customize peptoids and therefore the properties of the peptoid nanosheet, it has possible applications in the areas of drug and small molecule delivery and biosensing.
