Hanging Droplets from Liquid Surface was recently published in the Proceedings of the National Academy of Sciences by Ganhua Xie*, Joe Forth, Shipei Zhu, Brett A. Helms , Paul D. Ashby , Ho Cheung Shum and Thomas P. Russell*. The researchers show that coacervate-encased droplets of an aqueous polymer solution can be hung from the surface of a less dense aqueous polymer solution using surface tension. The forces acting on and the shapes of the hanging droplets can be controlled. Sacs with homogeneous and heterogeneous surfaces are hung from the surface and, by capillary forces, form well-ordered arrays.
