Osmotic stress, crowding, preferential hydration, and binding: A comparison of perspectives.

abstract：:Patchy particles with shape complementarity can serve as building blocks for assembling colloidal superstructures. Alternatively, encoding information on patches using DNA can direct assembly into a variety of crystalline or other preprogrammed structures. Here, we present a tool where DNA is used both to engineer sha...
