When light falls on the nanotubes, they release energetic charge carriers, which split the water molecules inside them into two reactive components - hydroxide radicals and hydrogen ions.
当阳光照射在纳米管上时，纳米管释放出高能量的载荷子，使得水分子分解为两种活性成分-氢氧自由基和氢离子。
Ferguson said this was done to shield the particles from the air because the silicon nanopowder is so reactive it could theoretically generate hydrogen with exposure to even minimal amounts of water.
Ferguson说这样做避免了纳米硅颗粒与空气中微量水发生反应的可能性。
These rogue oxygen atoms can remain on their own or combine with hydrogen atoms to form reactive oxygen species (ROS), which wreak havoc with enzymes and proteins and adversely affect cell function.
这些游离的氧原子能维持它们自己的形式或者和氢原子联合成活性氧(ROS)，ROS能被酶和蛋白分解可逆性影响细胞功能。
