title: The ins and outs of molecular encapsulation.
abstract: Molecular capsules can act as hosts for appropriate guests, and bring them into well-defined nanoenvironments. Various spectroscopic methods have been used to deduce the mechanism of guest exchange in such systems. Generally, the guests get in and out of capsules through the opening and closing of host "flaps" but smaller capsules can exchange simply by dissociation of the host subunits.
