The combination of DNA-origami and synthetic polymers paves the way to a new class of structurally precise biohybrid nanomaterials for diverse applications. Herein, we introduce the grafting to method with high conversions (70-90%) under ambient conditions to generate DNA-polymer conjugates, which can hybridized precisely to DNA-origami architectures. We generated homo and block copolymers from three different polymer families (acrylates, methacrylates and acrylamides), coupled them to single stranded DNA (ssDNA) and pattern different DNA-origami architectures to demonstrate the formation of precise surface nanopatterns.
DNA折纸术与合成聚合物的结合为一类新型结构精确的生物杂交纳米材料开辟了道路,可用于多种应用。在此,我们介绍了在环境条件下具有高转化率(70-90%)的接枝到方法,以生成可与DNA折纸结构精确杂交的DNA-聚合物共轭物。我们从三种不同的聚合物家族(丙烯酸酯、甲基丙烯酸酯和丙烯酰胺)生成了均聚物和嵌段共聚物,将它们与单链DNA(ssDNA)偶联,并对不同的DNA折纸结构进行图案化,以证明精确表面纳米图案的形成。
