Peptoid Nanosheets at the Oil/Water Interface
Berkeley CA (SPX) Sep 12, 2014
From the people who brought us peptoid nanosheets that form at the interface between air and water, now come peptoid nanosheets that form at the interface between oil and water. Scientists at the U.S. Department of Energy (DOE)'s Lawrence Berkeley National Laboratory (Berkeley Lab) have developed peptoid nanosheets - two-dimensional biomimetic materials with customizable properties - that self-assemble at an oil-water interface. This new development opens the door to designing peptoid nanosheets o ... read more
