Development of novel graphene nanopore sensor for DNA sequencing

这项研究在过去一年中顺利进行。我们在研究项目中取得了以下重要成果：1.提出了一种在悬浮单层石墨烯中钻取亚10 nm小孔的新方法，用于检测DNA单分子。我们已经成功地制作了具有纳米沟道的MEMS传感器件。这种新型的液体测试装置比普通的微/纳米通道装置简单得多，纳米通道的深度可以精确控制，单个分子可以沿着纳米通道引导单个分子穿过石墨烯中的纳米孔，实现DNA测序。

The research was smoothly carried out in the last year. We have made important achievements in the research project as following:1. We have proposed a new method for drilling sub 10 nm pore in a suspended monolayer graphene for detecting single DNA molecule.2. We have successfully fabricated a MEMS sensor device with nano-channel. This new liquid testing device is much simpler than the normal micro/nano channel devices and the depth of the nano-channel can be precisely controlled.A single molecule can be guided along the nano-channel to pass through the nanopore in graphene, realizing DNA sequencing.
