Following this design principle, the researchers create angstrom-scale pores in bi-layer graphene sheets, and decorate the two pore edges with twisted rings of carbonyl groups. The artificial ion ...

Potassium channels are openings that allow charged potassium atoms to cross the cell membrane. Voltage-gated potassium channels—which open only when a specific voltage is reached across the cell ...

(Nanowerk News) Intrigued by the properties of ion channel proteins commonly observed in cells, Tokyo Tech researchers have developed the first synthetic mechanosensitive potassium channel using a ...

Underlying every thought, heartbeat and movement are ion channels, busily conducting high-speed streams of ions into cells, like subway trains coursing through tunnels. Ion channels span the cellular ...

The composition of every living cell includes small, highly specialized conduits known as potassium (K +) channels that are responsible for the extremely selective and rapid transport of K + ions ...
