Nanoscience: Regulating the traffic across cells membranes

Nanopore-forming materials have many potential applications in chemistry and biology, including DNA sequencing. However, only very limited designs of synthetic nanopores exist in the literature. US scientists have made circular molecules made of sugars that can stack on top of one another to form a transmembrane pore and act as carriers to shuttle the guest molecules across the membrane.
