Self-Assembled Nanocrystal Membranes

nanomembraneClose-packed nanocrystal monolayers can be self-assembled by simple drop casting into ultra-thin free-standing membranes. Researchers at the University of Chicago MRSEC have shown that these membranes are remarkably strong, with a Young's modulus on the order of several GPa, yet highly flexible. The arrays remain intact and able to withstand tensile stresses up to temperatures around 370K. The purely elastic response of these membranes, coupled with exceptional robustness and resilience at elevated temperatures makes them excellent candidates for a wide range of sensor applications.
