從流感疫苗到破傷風針，注射在現代醫學中是不可或缺的。
But do they always have to makeyou say Ouch?
但是它們是否就一定會讓你尖叫呢？
Eh,no?
嗯,不會嗎？
No,indeed.If new microneedle technology is successful, we may soon have needles that inject medicine without your even knowing it.
真的不會！如果新的顯微針技術成功了的話，我們將很快享受甚至你都不能意識到的藥物注射。
How does this work, you ask?
你快問它是如何辦到的？
How does it work?
如何辦到的？
You feel things because of the nerves that are embedded in your skin.
你有感覺是因為你皮膚里鑲嵌的有神經。
However, the entiresurface of your skin is not covered.
然而，它卻沒有完全覆蓋你的皮膚。
From a microscopic viewpoint, there is plenty of spacebetween nerves where a super-tiny needle wouldn’t be felt.
在顯微鏡下可以看到，神經之間有很多空間，而在這里人們便感受不到微型針。
No way!
不可能！
Way! Researcher Mark Prausnitz and his coworkers at the Georgia Institute of Technology inAtlanta have already built micro-injection devices.
可能！亞特蘭大喬治亞理工學院的研究人員Mark Prausnitz和他的同伴們已經研制出了微型注射器具。
