Pingie: HTTP:: Environmentally Friendly Nanoparticle Production Method Created

HTTP:: Environmentally Friendly Nanoparticle Production Method Created
--------
Zinc oxide has been in use in the nanotechnology industry since its early days, and researchers in Saudi Arabia have now devised a non-toxic and environmentally friendly method of producing it en masse. In a paper published in the International Journal of Nanoparticles, the scientists show that this class of nanoparticles can be used safely for medial and other sensitive applications from now on, ScienceDaily reports. Zinc oxide is mostly obtained in the form of nanorods. These rods usually have less than 100 nanometers in diameter, which means that they have a lot of uses in many areas of science. They are employed, for instance, in breakfast cereals, where they act as a source of zinc, which is essential for the good functioning of the human body. They also appear in a large array of cosmetic products, sunscreens and lotions, and are known to efficiently protect the skin against harmful UV radiation, which can damage DNA and trigger the formation of skin cancer. The c!
hemical also plays an important part in gas-detector technologies. When gas molecules are absorbed in such devices, the oxide modifies their electrical properties in a detectable manner. It has also played a major part in the appearance of a new class of lasers and LEDs, and has been successfully used as a a biomimic me...
