Herein, we exploit direct laser writing as a means to fabricate negative masters for the generation of polymeric nanopillars, via replica molding. Through the optimization of design parameters, fabrication configurations, and polymerization protocols, we demonstrate for the first time the fabrication of large-area negative templates, which can be used to repeatedly produce some of the tallest (>1.5 μm) and thinnest (<300 nm) pillars achieved in biocompatible photocurable polymers, such as polyethylene glycol diacrylate, polypropylene glycol diacrylate, and polycaprolactone dimethacrylate. This combination serves to add value to two-photon polymerization and to extend its potential to the facile production of millimeter-sized arrays of submicron pillars of infinite combinations of height, diameter, and pitch, in a wide variety of compliant, biocompatible, and biodegradable materials.

直接激光写入以生成用于聚合物纳米柱复制的模具

在本文中，我们利用直接激光写入作为通过复制模制来制造用于生成聚合物纳米柱的负片的方法。通过优化设计参数，制造配置和聚合协议，我们首次展示了大面积负片模板的制造，该模板可用于重复生产一些最高（> 1.5μm）和最薄（<300）的模板nm）是在生物相容性光固化聚合物（例如聚乙二醇二丙烯酸酯，聚丙二醇二丙烯酸酯和聚己内酯二甲基丙烯酸酯）中获得的支柱。这种组合可为双光子聚合增加价值，并将其潜力扩展到以各种柔顺性，高度，直径和螺距的无限组合轻松生产毫米大小的亚微米柱状阵列，
