Cleaning groundwater with nanoparticles
As for the concern of the condition of the environment, it has become more and more pressing. Now is the time that we must think of new ways to solve these monumental problems. One of the most promising answers is nanoparticles. This new technology is now being researched in order to discover all of its potential. Within the environment the benifits seem promising, especially dealing with groundwater clean up.
One major problem is that over the decades different contaminates have been released into the the groundwater. This occurs through inproper disposal and storages of man-made products  , causing the groundwater to become unsafe for use. This is where the new technology of nanoparticles comes into play. These particles can be injected deep into the groundwater, where it would have been difficult to get to.
The main particle being used and researched at this time is ferritin [ http://arbl.cvmbs.colostate.edu/hbooks/molecules/ferritin.html] . Ferritin is iron that is also found in the blood. Through studies they have found that this particle can reduce contaminates down into a less harmful form [ http://www.spacedaily.com/news/nanotech-04zzq.html]. This can also make the contaminates easier to filter out of the groundwater when in wells.
