Ion channels are the life lines of living cellular organisms and have attractive applications in nanotechnology. Giant polyoxometalates, known as keplerates, form porous capsules with 20 pores that are capable of acting as ion channels. The behavior of aluminum cations at the surface of this artificial cell is under investigation by 27Al NMR. We will report the temperature dependence of the cation distribution equilibria within this system and also the kinetics of cation transport through the pores of this artificial cell.
