| Abstract: | Light‐controlled nanochannels are fabricated through self‐assembling azobenzene‐incorporated DNA (Azo‐DNA) strands to regulate ion transport. By switching between collapsed and relaxed states using visible and ultraviolet light alternately, the Azo‐DNA channels can be opened and closed because the conformation of Azo‐DNA changes, that is, Azo‐DNA is used as switchable controlling unit. In addition to sharing short response time and reversibility with other photoresponsive apparatuses, the Azo‐DNA‐based nanochannel system has advantages in good biocompatibility and versatile design, which could potentially be applied in light‐controlled drug release, optical information storage, and logic networks. |
