Caption
Graphic shows the bilayer structure of a living cell membrane, composed of phospholipid. A phospholipid consists of a hydrophilic or water-loving head and hydrophobic or water-fearing tail. The hydrophobic tails are sandwiched between two layers of hydrophilic heads. At the center, a channel is shown, permitting the transport of biomolecules. The new study describes a process for creating artificial channels using segments of DNA that insert into cell membranes and allow the reversible transit of various cargo, including ions and proteins.
