Award for turning wool into gold

Aug 31, 2009

A Victoria University (New Zealand) scientist has won a prestigious innovation award for turning pure New Zealand Merino wool into gold.

Professor Jim Johnston was this week awarded one of five 2009 Bayer Innovators Awards for developing a world-first process in which nano-particles of pure and silver are embedded in New Zealand merino wool to create a luxury fibre that can be used in high-end fashion garments, textiles and carpets.

Professor Johnston, from the School of Chemical and Physical Sciences and the MacDiarmid Institute for Advanced Materials and Nanotechnology, received the top award in the Research and Innovation category, one of five categories in which the national award was made. Other categories included Information Communication Technology (ICT), Health and Science, Agriculture and Environment, and Design and Engineering.

"It is fantastic to be recognised and to have this degree of confidence shown in the cutting-edge research work that we're doing in our research group," says Professor Johnston who received his award from the Minister for Research, Science and Technology, Hon Dr Wayne Mapp.

Professor Johnston first developed the concept of using gold nano-particles as stable colourants for Merino wool in 2006 and since then the Research and Development has been progressed with his Victoria University PhD research students Kerstin Burridge and Fern Kelly, and recently with Dr Aaron Small. He has also been working with AgResearch in Lincoln on some aspects of the product testing, and the World Gold Council, London has contributed important funding. Earlier this year, small quantities of gold and silver infused wool were spun into yarn and woven into scarves and made into carpet samples in the UK.

Professor Johnston says the technology has already attracted great interest from the New Zealand wool industry, Italian and UK designers and manufacturers, and estimates the process could become a commercial reality within 12 months. The group is working with New Zealand Trade and Enterprise and prominent New Zealand, UK and Italian companies to progress the technology and products to commercialisation.

"This is a very clever technology which does not require a huge, expensive plant and, from a New Zealand point of view, it proves that you don't have to be big but can open new high value opportunities through innovative science. With this technology, we are giving the New Zealand wool industry a boost by creating a unique added-value material with its own distinctive properties for high-end markets."

This is a potentially hazardous technology, those nanoparticles will certainly be coming off and since they are capable of passing through the skin they will end up in the system of the person wearing the garment and in the environment.

Materials like that should be banned until the effects of such nanoparticles on human health are fully understood.

Banning them would be a bit extreme, especially since the whole basis of your comment is the assumption that they will come off.

There should be awareness however so that people can properly investigate this point.

sounds like a scam to me. selling golden 'infused wool' for the price of pure gold. someone will buy it.

of course some rich idiot will buy it, if it ever became commercially available, but does no one else think that this is pretty cool anyway??

I wonder if Jim Johnston bears any resemblance to Rumpelstiltskin, the dwarf who spun wool into Gold in one of the fairy stories of the brothers Grimm?

Ah, I thought gold was a good conductor of heat, won't it degrade the wool's performance?

Guess if they can afford it, they won't mind!

'Golden Fleece' puns, any-one ??

IIRC, one hypothesis holds that legend originated from herders' habit of leaving naturally greasy pelts in auriferous streams to accumulate micro-particles of gold...

Then again, the golden fleece story and such may represent remnants of records detailing the superior technological knowledge of past human civilizations in which the type of nanoparticle work described here was already known and commercialized.

I've actually seen this done in the republic of Georgia. And archeologists speculate this is where the myth comes from. Furthermore, Georgia is where the Argonauts went looking for the golden fleece.
