1·When the researchers looked at the seedling tissues under an electron microscope, however, they could see the nanotubes had actually entered living cells.
然而，当研究者在电子显微镜下观察种子组织的时候，他们能够看到纳米管确实已经进入了活细胞。
2·The tag USES ink laced with carbon nanotubes to print electronics on paper or plastic that could instantly transmit information about a cart full of groceries.
该标签利用掺有碳纳米管的油墨将电路印刷到纸或塑料上，瞬间便能读取满满一购物车里各类商品的信息。
3·But carbon nanotubes are very expensive to make, especially in large quantities.
但是(尤其是大规模)制造碳纳米管是非常昂贵的。
4·While the device is certainly in its earliest stages of development, the discovery does show that carbon nanotubes can efficiently convert light to electricity.
虽然这种设备还处于最早期的开发阶段，这一发现确实表明了碳纳米管可以高效地将光转化为电能。
5·And, crucially, is it not yet known if the nanotubes will find their way into the fruit of fully grown plants.
而且很重要的是，目前还不知道纳米管是否能够找到途径进入成熟植株的果实中。
