English Caption: 

Peptoid nano sheets like the one shown here are among the largest and thinnest free-floating organic crystals ever made, with an area-to-thickness equivalent of a plastic sheet covering a football field. Peptoid nanosheets can be engineered to carry out a wide variety of functions.

Recently, scientists at the U.S. Department of Energy (DOE)’s Lawrence Berkeley National Laboratory (Berkeley Lab) developed peptoid nanosheets that form at the interface between oil and water. These two-dimensional biomimetic materials with customizable properties self-assemble at an oil-water interface, rather than the traditional air and water interface. This new development opens the door to designing peptoid nanosheets of increasing structural complexity and chemical functionality for a broad range of applications, including improved chemical sensors and separators, and safer, more effective drug delivery vehicles.
