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.
通过将偶氮苯键合寡核苷酸作为调节剂和聚（L-赖氨酸）-接枝-葡聚糖（PLL-g-Dex）作为伴侣聚合物结合起来，以促进链置换，我们成功开发了一种光调控的 DNA 等温扩增方法。通过交替进行 UV 和可见光照射，实现了线性扩增。该方法可实现光调控，并在 DNA 靶标的线性扩增中实现错配识别。
