2015考研英语阅读医用植入设备

　　而一个葡萄糖供能的移植设备可以解决这些问题。葡萄糖由人体的循环系统被源源不断的输送到人体各处。一个糖分供能的设备因此能够取得持续供给的能量并且几乎可以在任何位置进行移植。

　　One approach, which has been employed by Sameer Singhal, a researcher at the CFDResearch Corporation in Alabama, involves the same enzymes that break down glucosewithin a living cell. Using carbon nanotubes, he and his colleagues immobilised two differentenzymes on the electrodes of a fuel cell, where they generated electricity by freeingelectrons from glucose. At present, only two of the 24 available electrons in a single glucosemolecule can be harnessed, but refinements to the technology should boost that number.

　　就职于Alabama的CFD Research Corporation的研究人员Sameer Singhal所使用的方法涉及利用酶将活细胞中的葡萄糖分解。利用碳纳米管，他和他的同事在燃料电池的电子上找到了2种不同的酶，在燃料电池中他们通过释放葡萄糖的电子来产生电能。现在，在一个葡萄糖分子中的24个可用电子中只有2个可以利用，但是对这项技术的后续完善应该会使得可以利用的电子数量有所增加。

　　Dr Singhal has implanted prototype devices into live beetles. Fitted with a fuel cell about thesize of a penny, the bionic bugs were able to generate over 20 microwatts during a two-week trial.
