Host-guest chemistry is one of the most focused research realms in modern chemistry.

主客体化学是当今化学研究领域的热点。

What we found, again and again, was that the strategies that were the most focused, the most targeted, the stickiest strategies, were the most successful.

我们一次又一次发现，最集中、最精准、最具粘性的策略，成效最为显著。

But the one that I'm most focused on is how can we open a gateway so that in the future, we can find hundreds of Earths.

不过我重点在研究的是要如何实现这样一个途径，在未来可以让我们找到数百个类地行星。
