Nanoparticles: these units are larger than atoms and molecules. They do not obey quantum chemistry, nor the laws of classical physics, having their own characteristics (+ on theoretical concept).
They are in the short term as one of the most immediate applications of nanotechnology with products and sectors that are already present in the market.
Nanoparticles are advancing with almost daily discoveries on many fronts. This is the case of biosensors, iron-based nanoparticles against cancerous tissues, etc. In general, biomedicine and biotechnology are two very promising fields of potential applications.
Obviously we are referring to nanoparticles created artificially through particle engineering in laboratories, created at the nanoscale by researchers.
There is already a "catalog" of nanoparticles in research or commercialization. Some of them: Doped Zinc Oxides, Mixed RareEarth Metal oxides, NanoArcTM Bismuth Oxide, NanoArcTM Cerium oxide SGH, NanoArcTMCopper oxide, NanoDurTM Aluminum oxide, NanoGard® LL Zinc oxide, USP, NanoGard®Zinc oxide, USP, Nanophase Zinc oxide NanoTek® Aluminum More information on these products in Nanophase.
In March 2004, researchers from Carnegie Mellon University created nanoparticles capable of cleaning contaminated sites and eliminating polluting toxic elements. It had a wide media coverage.
