Nanoparticles Purifying Water: All Hype or Reality?

Recent findings that say nanoparticles can help purify water seem like something you can expect from a science fiction movie or something that you can read from a book by Jules Verne. Can nanoparticles really help give us cleaner and purer water, and if so, how does it work to do this?

When you talk about nanoparticles, you may begin to visualize those little robots that a certain cartoon character developed to help him with certain tasks and deeds. These are nano-bots and are not what scientists in universities in Mexico have developed in order to help clean water of toxic substances in less than an hour.

How this happens seems to need the power of the sun or of ultraviolet light to complete the purification process. What the researchers in these universities used was titanium oxide nanoparticles that have been made to adhere to glass with the use of heat.

Once water in these glass containers that have been treated with these nanoparticles is hit by sunlight or by UV rays, the water is then purified. Read the rest of this entry »

Nanoparticle Patents

In the late 1970’s and early 1980’s, nanotechnology was nothing more than a vague pipe dream, but the sheer number of nanoparticle patents being filed shows us that those days are officially over.

Today we can see hard proof that it has become a full-blown reality, as more scientists and research groups devote themselves wholly to the pursuit of nanotechnology.

Each of these groups is likely to find a new and different application for nanotechnology, since it is an extremely universal discipline.

Nanoparticle Masks and Goggles

Most people who know about nanoparticle masks probably wish they didn’t, since these micro-filtering protection devices first entered public awareness during the SARS outbreak of 2003.

These masks have been equipped with a filtration system that uses clusters of nanoparticles to remove microscopic biological pathogens from the air, and they were a huge success in Asian countries where the SARS epidemic hit hardest.

Now that the initial fear has faded, nanoparticle masks are once again on the margins of public attention. But the fact remains that they can perform an array of useful functions and may become indispensable in the event of a future disease outbreak.

How do nano-masks work? A molecularly enhanced particle coating is put on the mask’s filter; the nanoparticles in the coating have a tendency to cluster together enough to create a layer of ions that works together with trace amounts of chlorine to catch and eradicate any undesirable particles they encounter.

What is Nanotechnology Used for Today?

Have you ever caught your self wondering , just what is nanotechnology used for today? Nanotechnology controls matter on an atomic level, modifying its effects to achieve desired results. Its uses are therefore extremely numerous.

Any substance in existence can be broken into molecules and tampered with in order to give it different properties and abilities.

The universality of nanotechnology means that it is being applied to almost every facet of modern life. Miraculous effects can be achieved by engineering nanoparticles; for example, researchers have already developed wool and silk that can clean themselves because their altered particles “eat” stains.

Self-cleaning household products are also being developed. The time is not far distant when you’ll be able to spray a nano-chemical onto the grime in your kitchen and watch it disappear and practically never come back, since many nano-chemicals also prevent grime from accumulating.

Medical robot

Researchers have also developed “nanocomposites,” a cluster of nanoparticles from different elements that can, among other things, solve the pollution problem. The Pacific Northwest National Laboratory, for example, has discovered how to alter silica particles so that they attract and capture toxic particles in water.

The Potential Disadvantages of Nanotechnology

As impressive as nanotechnology might be, there are also potential disadvantages of nanotechnology. Some of the problems with nanoscience are practical while others fall under the ethical realm.

Practical problems can include everything from the need for mass produced forms of nanotechnology that may or may not be possible.

Ethical problems can include everything from the potential direction nanotechnology might take to the problems with the possible effects of the products created. Read the rest of this entry »

Applications of Nanotechnology

There are numerous applications of nanotechnology. Most of the applications come as a surprise to your average person.

However, once it’s explained, it makes perfect sense. Many everyday products are the direct result of nanotechnology applications.

The manipulation of particles that are smaller than most people can imagine is able to create products that enrich our everyday lives.

Nanotechnology involves the creation of material derived from the manipulation of particles as smaller than atoms. Manipulations of these microscopic particles allow scientists create all kinds of products that we use on a regular basis. Read the rest of this entry »
