Gold for Good

Gold for Good

I first came across the World Gold Council back in 2002 at a nanotechnology conference in Ireland. While most gold goes into jewellery, and doesn’t require too much marketing, a growing amount goes into high technology applications, everything from microelectronics to drug delivery.

Today we can publish the fruits of our recent collaboration with the World Gold Council, a white paper called “Gold for Good” which looks at the history of gold and nanotechnology.

One of the most fascinating parts of working on this publication was the realisation that gold nanoparticles have been used for several millennia, from the Romans to Michael Faraday, but it is only recently that we have been able to understand why they have the properties that they do, which has led to a host of other applications.

While the World Gold Council is often seen as a marketing organisation, they do actually invest in companies making use of gold – for example Nanostellar who use gold nanoparticles in catalysts to reduce diesel emissions.

Good for Gold!

 

The UK’s House of Lords is to publish its long awaited report on “Nanotechnologies and Food” this week, but it’s all top secret until a minute past midnight on Friday. We’re curious to see whether the report contains some of oft quoted but wildly inaccurate numbers and/or calls for the usual ‘further public consultation’ or indeed whether there are any actionable conclusions at all, something sadly lacking in UK government science and technology publications of late.

Reports from some of the folks interviewed  suggest that the committee wasn’t the stereotypical bunch of old buffers put out to grass and that there was some real knowledge involved. You can see the evidence given here, and a bit about how the UK Government views nanotechnology and food here.


 

Migrating Buckyballs

Luna's Trimetaspheres

Arrowhead Research announced today that it had sold off the IP of one of its subsidiaries, Tego, to Luna Innovations in exchange for $430,000 less legal and transaction fees in exchange for a cut of any proceeds. Luna of course have been looking at buckyballs for improved MRI contrast agents – careful here! it’s a tricky subject –  for quite a while using the wonderfully named trimetaspheres.

The basic idea is great. You can take a nasty toxic substance such as gadolinium that happens to show up very well in MRI scans, and encase it in a fullerene cage so that all the patients body sees is carbon. However as with much to do with fullerenes, producing anything that works at a cost that is even vaguely competitive tends to be far tougher that originally envisaged.

So what we are seeing is an ongoing migration of various bits of nanotech IP towards companies that can turn them into a useful application. This particular bit of IP came from Carbon Nanotechnologies Inc whose plans for global domination included hoovering up every bit of carbon related IP they could fund and worrying what to do with it later.

 

The European Union is to make the labelling of nanomaterials in cosmetics mandatory according to Chemistry World.

The cosmetic regulation states that all ingredients present in the product in the form of nanomaterials should be clearly indicated in the list of ingredients, by inserting the word ‘nano’ in brackets after the ingredient listing. The ruling defines nanomaterial as ‘an insoluble or biopersistant and intentionally manufactured material with one or more external dimensions, or an internal structure, on the scale from 1 to 100 nm’.

As always, the devil is in the details and the detail in question is the definition. While one of the advantages of nanotechnology is that it allows you to control very tightly the size range of the particles that you are creating, top down technologies such as milling and grinding tend to produce particles with a wide range of different sizes, and while the mean size may be above 100nm, that does not mean that there will not be any sub 100 nm particles present. I suppose the definition of ‘intentionally manufactured’ is also open to question.

I have seen a number of ads recently for ‘chemical free’ cosmetics – which once again depends on whether you class tea tree oil and water as chemicals or not, and nanoparticle free cosmetics are a similar oxymoron. Depending on the production method used, the mean particle size could have to be as large as gravel in order to be even 99% nanoparticle free.

Germany has adopted the EU proposals with the caveat that

the general mention on labels of nano-scale materials in cosmetic products using the term “nano” might be misunderstood by consumers as a warning.’

While labelling may assuage some of the regulatory concerns, will the average consumer would be any more concerned with labelling the nanoparticle containing ingredients than they are with currently permissible constituents. Grabbing a bottle at random from my wife’s dresser I find a long list of ingredients such as Methyl Glucech-20, PEG-12 Dimethicone, and Polyquaternium-4, and I can’t really see that putting Hydroxyethyl cellulose dimethyl diallylammonium chloride copolymer (nano), or (C8H16N)x.xCl.(C2H6O2)x (nano) would make much difference compared with the power of the cosmetic company’s marketing machine.

And that’s before I get into another debate with a polymer chemist about whether or not polymers are nanotech!

I almost found myself agreeing with our neighbours (across the road from Foxbat) at the Ecologist, which gave me a bit of a shock.

The article in question concerned antimicrobials, and nanosilver in particular, and I have to admit that I’m more likely to be encouraging my kids to eat earthworms than to spraying them with antibacterial agents. As the old adage goes, you have to eat a peck of dirt before you die, and with good reason.

But we also have to ask, yet again: why have we become so frightened of ‘germs’ that we feel the need to go to ever more extreme measures to vanquish them? Are there really people out there so terrified of their washing machine becoming a festering mass of life threatening germs that they feel the need to invest in a nanosilver coated machine? And if there are, wouldn’t an investment in cognitive behavioral therapy be money better spent?

Well said, but then the article is spoiled at the last by the usual mindless invocation of the precautionary principle – which for some reason applies to nanotechnology but doesn’t apply to more obviously foolhardy and downright suicidal activities such as cycling to work in Spitalfields.

 

Nanotech Breasts

Unlikely bedfellows they they may be, there seems to be a connection in some minds, and it keeps cropping up.  Apparently, this is part of a full-page ad in the Singapore Straits Times of Thursday, Oct 15, 2009.

UPDATE from our correspondent in Singapore….

Hi Tim,

I’m in Singapore for a few days and there’s a full page ad in the Straits Times just like you said.

It says they use a Nano Serum with ” nanosized particles 2000 times smaller than the skin pores around the breasts. When coupled with the unique gentle massage of our therapists, these particles penetrate deeply…. to achieve enhancement, firming and contouring.”

So there’s a dream job for you!

 

foxbatToday’s Times has four writers explaining their ‘Eureka Moments’ with science, and proving that a lifetime in the arts is no barrier to getting to grips with science.

I’ve spent the past couple of months going the other way, and getting involved in fashion! I’ve long been fascinated by the creative arts, but my enthusiasm has been unmatched by my skill with a paintbrush or even a soldering iron, both of which have in the past raised gasps of astonishment. However, I recently found a way to reconcile nanotechnology with fashion by opening a boutique, Foxbat, in one of London’s hippest districts, Spitalfields.

The idea came about last year when the Victoria and Albert Museum organised an exhibition called ‘China Design Now‘ which illustrated how art, design and fashion was undergoing a renaissance in China.

China is huge. China is becoming topical. Yet China remains mystery to most people in the West. ‘Made in China’ has become a familiar tag, but the spectacular creative energy in modern China is barely known. During the last twenty years, the Chinese have rediscovered their pre-socialist past and begun to combine their own traditions with global influences to produce a cultural rebirth. At the heart of this lies a new culture of design.

Spending time in China last year I was struck by the new home grown brands of fashion & jewellery that were emerging to stand alongside the more well known European brands and the ubiquitous (in Asia) Burberry, and the idea was born to import the best of Chinese and Korean design to Europe. The quality is outstanding, and given the disparity between consumer buying power in London and Shanghai, some thing that would cost the equivalent of a thousand pounds in China can be retailed in London for two hundred! So it’s high fashion at high street prices, a credit crunch business model that appealed to me.

We finally opened Foxbat last week, on Brushfield St in Old Spitalfields Market after six months of negotiating leases, dealing with builders, plumbers, electricians, window cleaners. A week before we were due to open our interior designers flounced out in a huff after we criticised their tiny fitting room mirrors, leaving us to source everything ourselves at short notice.

So what about the nanotechnology? We have one of the largest collections of NeoGlory crystal jewellery outside China. NeoGlory also make all the crystals for a well known Austrian brand, but have now moved into producing their own designs, which are equally stunning but at a fraction of the usual prices. As some people may know, the days of mining crystal from the Austrian Alps ended a long time ago, and most crystal used in jewellery is lead crystal, often coated with a few nanometers of metal film to add colour and enhance sparkle.

So moving from nanotechnology to a boutique full of shiny sparkly girly stuff isn’t such a great leap after all!

Regular readers will know all about the saga of Oxonica, the small university spin out that managed an IPO and then spent the following few years bogged down in legal battles while losing 95% of its value before finally delisting and scattering its executives to the four winds – presumably before they were ripped limb from limb by irate shareholders.

Yesterdays announcement that the only bit of the company that ever looked like making any money – before a dispute about royalties erupted – has been sold to the company that they spent two years and several million pounds fighting is particularly ironic.

There’s a tale of hubris, greed and huge egos behind this, and one that will no doubt emerge in time.

 

The ‘Investors‘ page on the Oxonica site looks a bit bare today, after their de-listing from the AIM market yesterday. The move was billed as a cash saving measure. Presumably updating the web site less frequently is a similar tactic.

OXN

 

The company that most have pointed to as the UKs leading nanotechnology company, Oxonica, finds itself in the news again this week after losing the second round of its court battle with Neuftec, and becomes the latest company to find itself in difficulties after being saddled with a  huge legal bill.

Well, companies go bust all the time, and it is usually confined to the courts and the financial press, so it was surprising to se how personal this fight had become, with the dispute migrating from the Court of Appeal to the Daily Mail!

Where do we go from here, to the House of Lords and the News of the World?
