We designed these nanoparticles to be activated by these enzymes.

我们设计了这些会被酶激发的颗。

We have to sneak our nanoparticle past the tumor defense system.

我们要让骗过肿瘤的防御系统。

First, let's start with the nanoparticle core.

首先，我们要制造。

And in this case, the immune cells in the liver are less likely to eat the biological nanoparticles.

这样，肝里面的免疫细胞就更不会吞噬这些子。

They injected special nanoparticles into their eyes. These tiny particles let the mice see better in the dark.

他们给老鼠的眼睛注射了特殊的子。这些小微让老鼠在夜间看得更清楚。

" We actually developed nanoparticles, so-called up-conversion nanoparticles, that actually can effectively be activated by this near-infrared light."

“我们实开发了子，所谓的转换子，实可以被这种近红外光有效地激活。”

It`s based of these amazing properties of nanoparticles that only react to one specific molecule.

是基于子的神奇特性，们只对一个特定的分子有反应。

And guess what? Our nanoparticle is considered a foreign object.

很显然，我们的子 就是一种外来物体。

He got help from a Minnesota company that uses a technique of spattering nanoparticles.

他得到了明尼苏达州一家公司的帮助，该公司使用了一种喷溅子的技术。

We can follow where those nanoparticles have been uptaken into, for example, human cells.

通过该仪器，我们能够了解的摄入方向，譬如说人类细胞。

The nanoparticles attach themselves to photoreceptors in the animal's retina.

颗附着在动物视网膜的感光细胞。

One way to tamper with the internal structure of concrete is to use nanoparticles.

使用子可以改变混凝土内部结构。

And we can put different drugs into the nanoparticle core.

我们还可以在内中 放入不同种类的药物。

And the immune cells in the liver eat the nanoparticles, preventing them from reaching the tumor.

肝里的免疫细胞会吞噬子，让们到不了肿瘤。

But as those nanoparticles degrade, they release the silver from their metallic core, which may be harmful.

但是随着子的不断降解，们会从金属磁芯中释放有害的银离子。

This new nanoparticle technique is stealthy and it do[es] not need external power.

这种新的颗技术是隐形的，不需要外部电源。

The nanoparticles remained active for as long as two months.

颗的活性长达两个月之久。

So unless they have this nanoparticle protection, they will not be able to function.

所以除非们有这些子的保护，否则们就不会发挥功效。

So our group helped pioneer a method, a technology, whereby we could tag nutrients with nanoparticles, fluorescing nanoparticles called quantum dots.

于是我们团队帮助开拓了一种方法，一种技术，用颗标记营养物质，荧光颗叫做量子点。

And I'm here to tell you that nanoparticles are the fire trucks.

我认为子就是我们所需要的工具。
