Gold nanoparticles enrich every day products

May 05, 2010

(PhysOrg.com) -- Durable paint, water purification, faster computers, tougher shoe soles, and lighter and cheaper televisions are all possibilities now that a Queensland University of Technology (QUT) scientist has discovered a way to disperse gold nanoparticles evenly through plastic.

Adrian Fuchs, from QUT's School of Physical and Chemical Sciences, said the technique he had developed was a model for dispersing metals in nanoparticle form throughout polymers or plastic materials.

"The properties of metals change when they are in nano form and so combining the unique property of nanoparticles with plastic leads to a whole new range of composite materials that could be used for novel catalysts, , and coatings," Dr Fuchs said.

"Paint is essentially a plastic so when are added it makes colours more intense across the whole visible spectrum. The paint would also be more durable when exposed to a harsh environment."

Dr Fuchs said gold had good conductivity and became a useful catalyst when mixed with different metals.

"If you put gold nanoparticles with using a plastic mould, you can make a very efficient catalyst to purify water; the titania absorbs the light and converts it into electricity which is then passed into the conductive gold," he said.

Dr Fuchs said his method for dispersing through plastic could also be applied to encapsulating drugs into plastic casings so that they could be ingested and used for cancer detection and destruction.

What?

"encapsulating drugs into plastic casings so that they could be ingested and used for cancer detection and destruction"
You want to rap our drugs in plastic so they will be digested? This makes no sense, humans can't digest plastics, so you wouldn't absorb any of the drugs. And how the heck would it affect the effectriveness of cancer setection.

Gold mega-particles would enrich products even more :). I always wanted a solid gold toothbrush.

Our two contributors should remember that "it is better to remain silent and be thought a fool than to speak and remove all doubt"
My money is with Dr Fuchs and the detection and destruction of cancer potential.

Sounds like a clear case of "I don't understand it so it must be wrong" syndrome.

The fact is not all plastics are the same, "plastic" is a general term for a wide array of synthetic materials.

Also, the article said INgested, not DIgested... so presumably the point was to make them non-digestible.

True gold moatatomics with the correct deformed orbital and elctro-charge levels (a three stage process to get there, and a good year+ of work) as described in the alchemical works of legend (over 6000 years old) can do incredible things that science and modern medicine has barely begun to scratch the surface of.

These works were purposely disguised and hidden from casual understanding and purposely disguised in their descriptives (for making) so that it would only become evident to a very determined and intelligent man. Balanced pydhcology and a clear head in the human 'grounded' sense was also required to understand what the texts were -and are- saying.

As you can see from some of the above comments...this was a good idea, was it not? Think it through and go find yourself some true alchemical texts. Remember, a clear head -in all ways- will be required. Then it will reveal itself. It's not just hard linear work, it requires the use of expanded lateral thinking as well.
