title: Smooth Muscle Cell-Mimetic CO-Regulated Ion Nanochannels.
abstract: A CO-regulated ion nanochannel is demonstrated, which is inspired by the living activity of CO-induced smooth muscle vasodilation. The mechanism relies on the fact that CO has a higher affinity with ferroporphyrin compared to carboxyl groups on the surface of the nanochannels. The cooperation effect of the released carboxyl groups and the conical asymmetric shape leads the ion transportation to be diode-like.
