Gold Nanorods: The Diversified Usage In Nanotechnology
Gold nanoparticles are assemblages of 40 to 30 million of gold atoms, typically of size between 1 and 100 nm. For some time, they greatly interested the scientific community because of newly discovered or better understood properties. There have been reviews done on these properties of Au nanorods in the field of catalysis, optics with plasmon resonance, electronics, biology and medicine. Also addressed the main methods of preparing gold nanoparticles and their toxicity.
Gold fascinated mankind for millennia. This fascination is not only the result of ancestral customs or social conventions. Scientific knowledge provides an explanation for the attraction elements. Indeed gold is the best known of the metals found in the native state, in the form of chips, for example with silver, copper and platinum.
The other metals, in contrast are extracted in their oxidized form and the corresponding reduction requires knowledge of metallurgy dating back to the Bronze Age (2000 years before our era about) and who have not ceased to be perfected throughout the history of mankind.
Moreover gold is the only metal with copper, not to be grey. As more, it is chemically stable (unchangeable), it keeps its properties indefinitely. That is why it is called a noble metal. We now understand why gold has always been the ideal metal for jewellery. Even today, about 2500 or 3000 tons of gold mined each year is added with several hundred annual discounts on the market. In recent years, the main use of gold nanorods remains jewellery (2400 tons), followed by the electronics with electrical contacts (450 tons) and dentistry (70 tons).
However, this fascination for gold wins scientists for twenty years, but for almost diametrically opposed reasons. The gold nanorods appear as three features that are at the root of the current enthusiasm of the scientific community: first they have better chemical reactivity of metals deemed “good catalysts” then the gold nanoparticles are more yellow, and finally gold being biocompatible nanoparticles can be used for medical purposes.
Gold nanorods: Know more beyond the boundaries
The nanorods help in different aspects that combine physics, chemistry and biology and illustrate how this area of research goes well beyond the traditional boundaries of disciplines. These are gold nanorods assemblies’ three dimensions between the nanometre and one hundred nanometers, that is to say a few atoms to a few million atoms. Against by the gold films or nanowires, only one or two dimensions respectively are nanoscale, are not discussed here. Nanoparticles can be monocrystalline, polycrystalline, spherical or elongated.
Why to buy nano gold rods online?
With the increase of Au nano rods in nanotechnology, there has been a tremendous increase in the number of suppliers. These days, there are a lot of varieties of nano rods available in market. You need to understand the requirement and use of each before buying. Since this thing has become lucrative, do not fall into false trap of suppliers.
If you are not an expert, you read customers reviews for details. Reviews are one of the powerful tools to know in detail about the product. They are genuine and you can know more about the product before actually buying it.
