That is when " the controlled drug delivery system can deliver a specific drug to that specific location."

此时药物传输系统就会将药物输向指定位置。

So what I'm really trying to say is we need a better drug delivery system.

所以我真正想说的是我们需要一个更好的药物输送系统。

" And once the sensor, you know, senses an abnormal increase in temperature, for example, It will send out a command. Then the controlled drug delivery system can deliver a specific drug to that specific location."

“比如，一旦传感器感知到温度异常升高，它就会发出指令， 然后受控的药物传输系统就能向特定的位置传输特定药物。”

And they use these microspheres to develop drug delivery systems for all kinds of drugs, one of them—some of them can treat cancer. One of them has actually been used in over five million schizophrenic patients.

他们用这些微球体来开发各种药物的药物输送系统，其中一种——其中一些种类可以治疗癌症。其中一种实际上已经被用于治疗超过五百万的精神分裂症患者。
