Chaperone‐Polymer‐Assisted, Photodriven DNA Strand Displacement
Copyright policy )Chaperone‐Polymer‐Assisted, Photodriven DNA Strand Displacement
AbstractPhotodriven DNA strand displacement by using a 2′,6′‐dimethylazobenzene‐tethered strand and poly(l‐lysine)‐graft‐dextran (PLL‐g‐Dex) as a chaperone is reported. Rapid strand displacement was reversibly induced by UV and visible‐light irradiation without any toehold portion. To further improve the method, the concentration of PLL‐g‐Dex and the number of equivalents of the photoresponsive strand were optimised. Optimally, 64 % strand displacement was reversibly induced by alternating UV and visible‐light irradiation.
