Artificial cell membrane channels composed of DNA can be opened and locked with a key

Scientists describe the design and construction of artificial membrane channels, engineered using short segments of DNA. The DNA constructions behave much in the manner of natural cell channels or pores, offering selective transport of ions, proteins, and other cargo, with enhanced features unavailable in their naturally occurring counterparts.
