One Step Closer into A Cleaner Environment... Water Purification

Nanotechnology, the scientific engineering of nanometer scaled objects, obtains a promising future in the field of water purification. Today nanoparticles are used for the removal of chemical and biological inhibitants in bodies; howver they can easly be used to treat unsanitary water in third world countries.

The process for nanoparticles to elimate the bacteria and germs consumed in unsanitary drinking water is shown  in the diagram below:

"Reverse osmosis–feeding water through a semipermeable membrane to filter out impurities–is widely considered to be the most effective way to desalinate water." (6.3) 

 

However, adding permeable nanoparticles to membranes can dramatically increase the efficiency in which water can be thoroughly filtered. The material used for reverse osmosis is "usually an organic thin-film membrane, typically a polymide material perforated with tiny holes". These holes are tiny enough to let water pass through, yet simutaneously block other contaminants.

 

 

Drug Delivery in an Instant with Nanoparticles

(6.4)

Like previosuly stated, nanotechnology is the field in which objects are found at the nanometer scale, in other words, 1 to 100 nanometers. A big aspect of nanotechnology is the development of nanoparticles. Nanoparticles are objects created very small, in order to behave in a certain manner. Another major impact nanoparticles has today, is in the drug delivery option.

 

Nanoparticles (NPs) containing encapsulated, widespread, differentiated drugs have unique characteristics that can lead to enhanced performance in a variety of dosage forms. When formulated correctly, drug particles are resistant to settling, thereby administering rapid onset of therapeutic action . Furthermore, a large amount of nanoparticles reside at the particle surface, which maximizes the loading and delivery of therapeutic drugs to any targeted cells and tissues.

Nanoparticles could also potentially reduce the drug dose needed to achieve therapeutic benefit, and as a result would reduce both the cost and side effects associated with specific drugs. Furthermore,a definite targeting can be achieved by attaching antibodies or aptamers on to the surface of particles or with the use of magnetic nanoparticles. They also have the ability to control a drug during transport to, or at, the site of localization, which all in all improves therapeutic efficiancy and reduces side effects.
