Eh,no?

How does this work, you ask?

From a microscopic viewpoint, there is plenty of spacebetween nerves where a super-tiny needle wouldn’t be felt.
在显微镜下可以看到，神经之间有很多空间，而在这里人们便感受不到微型针。
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！亚特兰大乔治亚理工学院的研究人员Mark Prausnitz和他的同伴们已经研制出了微型注射器具。
