Oxide nanoparticles

Oxide nanoparticles with a big impact in medicine and surface coating

Oxide nanoparticles are composed of iron oxide or any other metal with an oxidizing potential comparable or higher than that of iron. They are used in a wide variety of products, including medicine, paints, electronics, catalysis, alternative energy generation etc. Of course, as in many other areas of nanotechnology, there remains a lot to explore and to improve to exploit oxide nanoparticles’ full potential.

Oxide nanoparticles in surface coatings - a way to ensure sterility

One of the greatest dangers in hospitals are the so-called hospital germs. Contraction and transmission of these germs usually take place in the hospital, and the resulting diseases can be fatal for elderly people and young kids. The source of the problem is usually that regular detergents can no longer clean the surfaces, contaminated with bacteria and viruses, in a way to guarantee surface sterility. Sometimes, following sterilization, presence of new viruses and bacteria will lead to repeated contamination. This combination may lead, in some occasions, to the emergence of those feared hospital secondary infections and diseases.

Surface coatings with oxide nanoparticles exhibiting antimicrobial properties is one strategy to counter the formation of those resistant germs. The consequence of such coatings is that germs and bacteria can no longer adhere to surfaces treated this way, or get oxidized owing to the photocatalytic properties of nano oxides.

Oxide nanoparticles in paints – for the perfect oxide hue

The use of iron oxide in dyes dates back to paintings in the antique. Also today, the iron oxide color is present in colors for paintings as well as the more technical area of paints and varnishes. Addition of oxide nanoparticles to the standard paints improves their shine and results in a more advantageous light reflection. The main cause for this effect is that the use of nanoparticles leads to an increased particle surface offering a higher area for the light reflection (for a particular wavelength) and absorption (for the other wavelengths) and, ultimately, resulting in a brighter shine of the desirable color.

Oxide nanoparticles in medicine – a means for refinement

In current medical research, we find two main areas of application and research for nanoparticles. One area is that of cancer treatment. Here, the hope is that coating of oxide nanoparticles with drugs will improve drug absorption and thus improve care and treatment options for cancer patients. The other area is that of imaging methods where nanoparticles are used as radiopaque material. Here, the primary objective is to reduce radiation exposure during medical examinations. Infra-red absorbing and magnetic oxide nanoparticles (superparamagnetic particles) can be used for the local hyperthermic treatment of cancer by IR lasers or external alternating magnetic field respectively.

Oxide nanoparticles at PlasmaChem – a research area with many exciting developments

As a company pursuing the research and distribution of nanotechnologies and nanoproducts, we at PlasmaChem have an active interest in progress through scientific research as well as the exploitation of new markets. Especially because we trust in nanotechnology to find sustainable solutions to some of the fundamental problems of mankind. It is our interest to make a small contribution to this great overall purpose.

Along with the listed NanoCeramics many other ceramics were produced as trial batches, e.g. NanoCeramics from Rare Earth Oxides, HfO2, MgO+C, TiC, TiN, Y2O3. Basic technology permits to produce nearly any ceramic in nanosized form, thus we are expecting here the concrete wishes from our customers.
