Leigh and his team did something similar, but used metal ions as the "fingers" to keep the knot tying organized. Then tiny molecular strands, just 192 atoms long, assembled themselves around the ions.

利恩和他的团队做了同样的事情，但他们使用的是金属离子——一种类似“手指”的打结的组织，这种物质是只有192个原子长的微小分子链，聚集在离子周围。

"And then mum pulls her finger out — we extract the metal ions out — and you're left with just the knot at the end." the most complex molecular knot ever synthesized.

“然后妈妈把她的手指拉出来，我们提取出金属离子-剩下最后的结”，合成了最复杂的分子结。
