A simple method for selectively assembling colloidal particles with depletion forces is achieved using the concept of shape complementarity, reminiscent of Fischer's "lock and key" enzyme model. A spherical particle can fit inside a second particle with an indentation of similar size and shape (see figure), allowing access to a large variety of assembled structures.
