Abstract:
By combining azobenzene-tethered oligonucleotides as modulators and poly(l-lysine)-graft-dextran (PLL-g-Dex), a chaperone polymer, to facilitate strand displacement, we successfully developed a photo-regulatable DNA isothermal amplification method. By alternating UV and visible irradiation, linear amplification was achieved. The method enables photo-regulatability and mismatch discrimination in linear amplification of the DNA target.
