CREDIT Conticello Lab Abstract: Chemists have developed a nanomaterial that they can trigger to shape shift -- from flat sheets to tubes and back to sheets again -- in a controllable fashion. The Journal of the American Chemical Society published a description of the nanomaterial, which was developed at Emory University and holds potential for a range of biomedical applications, from controlled-release drug delivery to tissue engineering.
