Drilling precise nanopores in thin layers is in rapid demand for biosensing applications. We demonstrate that an energetic multi-wall carbon nanotube (MWCNT) can be a good candidate to fabricate nanopores on graphene from molecular dynamics simulations with a bond-order potential. High-quality nanopores with expected size and smooth margins could be created by an incident nanotube at chosen size and energy. Besides, a nanotube is in advantage of absorbing and translocating many biological macromolecules due to its strong adsorption capacity. It implies a feasible way to drill nanopores and carry big molecules through the fabricated nanopores in one step for fast biosensing applications.
在生物传感应用中，快速需求在薄层中精确钻制纳米孔。我们通过使用键序势能的分子动力学模拟证明，多壁碳纳米管（MWCNT）是在石墨烯上制造纳米孔的良好候选材料。通过选择大小和能量的入射纳米管，可以创建具有预期尺寸和光滑边缘的高质量纳米孔。此外，由于其强大的吸附能力，纳米管有利于吸收和转移许多生物大分子。这意味着可以为快速生物传感应用一步钻制纳米孔并通过所制造的纳米孔输送大分子提供一种可行的方法。
