Here we report on the generation of solid-state nanopores with controllable sizes and shapes based on direct laser writing with a computer-aided two-photon polymerization process. Through a theoretical and experimental study of the accumulation effect during the two-photon polymerization, we have achieved nanopores with an inner diameter of down to ∼λ/10 (76.9 nm) for the first time, which is far beyond Abbe's diffraction limit. The generated nanopores can be stacked to form a channel with desired asymmetric shapes. This work provides the potential to integrate the solid-state nanopores into functional devices and opens up a new avenue for optimizing the gating properties of artificial membranes.

固态纳米孔的3D计算机辅助纳米打印†

在这里，我们基于计算机辅助的双光子聚合过程，通过直接激光写入，报告了具有可控制的大小和形状的固态纳米孔的生成。通过对双光子聚合过程中累积效应的理论和实验研究，我们首次获得了内径低至λ / 10（76.9 nm）的纳米孔，这远远超出了阿贝的衍射极限。可以将产生的纳米孔堆叠以形成具有期望的不对称形状的通道。这项工作提供了将固态纳米孔整合到功能性装置中的潜力，并为优化人工膜的门控性能开辟了一条新途径。
