Membrane transport

Extracellular chemical signals that mediate a range of intracellular functions must either be directly transported across cell membranes or be bound to a receptor causing a response to be propagated into the cell interior. A variety of systems have evolved that can operate in this way, but designing synthetic systems that replicate such functions is not trivial. A collection of articles in this Focus discuss artificial methods for transporting chemical information across a lipid bilayer.
