本文介绍了使用DNA纳米结构模板的聚合物印章的制作。这个过程创建具有不同的纳米级特征的印模，其尺寸范围从几十纳米到微米。DNA纳米结构，包括DNA纳米管，拉伸的DNA，二维（2D）的DNA砖晶体与三维（3D）的功能，六角形DNA 2D阵列，和三角形DNA折纸被用作主模板转移图案到聚（甲基丙烯酸甲酯）和聚（L-乳酸）与高保真度。将所得聚合物印模用作模具以将图案转移到丙烯酰氧基全氟聚醚聚合物。这项工作建立了一种方法，使用自组装的DNA模板的软光刻应用。
This paper describes the fabrication of polymer stamps using DNA nanostructure templates. This process creates stamps having diverse nanoscale features with dimensions ranging from several tens of nanometers to micrometers. DNA nanostructures including DNA nano tubes, stretched lambda-DNA, two-dimensional (2D) DNA brick crystals with three-dimensional (3D) features, hexagonal DNA 2D arrays, and triangular DNA origami were used as master templates to transfer patterns to poly(methyl methacrylate) and poly(L-lactic acid) with high fidelity. The resulting polymer stamps were used as molds to transfer the pattern to acryloxy perfluoropolyether polymer. This work establishes an approach to using self-assembled DNA templates for applications in soft lithography.
