Suitable Process

Applications of various noble metal nanoparticles were investigated for newly, ecology and economy home electric appliances (microwave, ultrasonic) used system. Noble metal oxides have merit in metal particles fabrication, as one of these example example, there are decomposed by only heating in air. That is, noble metal oxide don't use strong reduction atmosphere. This reduction is ecologically clean, because many noble metal oxides are not toxic and during decomposition O2 is evolved. We have reduced noble metal oxides by microwave and ultrasound, and tried to fabricate noble metal nanoparticles, and investigated various processing. These energy are widely used by home electric appliances. By choosing suitable process and conditions, it is reasonable to expect that home electric appliances ecology and economy fabrications can be extended to obtain simply various noble metal nanoparticles related materials.

Suitable Process

Applications of silver nano-sized metal particles were investigated for a new, ecologically friendly and economical liquid-solid (silver oxide-alcohol) system. Silver metal oxides as starting materials have merits in metal particles fabrication because these materials are decomposed only by heating in air. That is, noble metal oxide does not use thestrong reduction atmosphere. This reduction is ecologically clean because many noble metal oxides are not toxic, and because O2 is evolved during decomposition. We reduced silver metal oxides by ultrasound and fabricated silver nano metal nanoparticles at room temperature, and various applications were investigated. By choosing a suitable process and conditions, it is reasonable to expect that ultrasonic eco-fabrications can be extended to obtain various silver nano-particles containing materials.

The Brain

metal nanoparticles have been used to address these diseases in the brain, however very few of these formulations have made it through clinical trials. This review will be discussing the role of noble metal nanoparticles as drug delivery systems specifically to the brain. A common problem many researchers and clinical physicians are facing problems because they are unable to access the brain without highly invasive surgery. Nanoparticles allow access to the brain without invasive surgery. Noble metal nanoparticles (NMNPs) are of particular interest because of their inherent characteristics which are amplified or reduced by ligands. The various ligands available change the method of transportation for a NMNPs traveling through the blood barrier. We will examine various ligands and their benefits and potential drawbacks. Furthermore, the optimal usage for each ligand and associated nanoparticle will also be examined. This review will go into detail about pure noble metal nanoparticle, glucose, PEG, CTAB, Transferrin, Anti-Microbial Peptide, and Chitosan as coatings. All of these are commonly used among researchers. The absorptivity into various cell types in the brain along with future implications will be examined.
