And that tiny spot where it says " S" , that's where nano particles of gold reside.

那个小点上面写着“S”，，那是金纳米粒子所在的地方。

As soon as that gold nano particle reaches that " T" level and the antibody grabs onto the COVID virus you're going to see that color change.

一旦金纳米颗粒达到 T 水平，并且抗体抓住新冠病毒，你就会看到颜色变化。

Scientists have also discovered that certain metals contain nano particles that have antibacterial qualities with the ability to destroy over 650 types of bacteria.

科学家还发现，某些金属含有具有抗菌特性的纳米颗粒，能够消灭 650 多种细菌。

And so if gold nano particle, plus Antibody 1, plus COVID virus, goes up to that " T" level, Antibody 2 now reaches out and grabs onto that COVID virus and locks it into place.

如果金纳米颗粒加，一号抗体加新冠病毒，上升，到 T 级，二号抗体现在伸出并抓住该新冠病毒并将其锁定。
