Nanotechnology research in Australia (see here) is mentioned in the Wired article Let’s get really small.

The article says that " Major breakthroughs are coming at a torrid pace. Earlier this month,
researchers in Texas and Australia reported success on an experiment to
build carbon nanotube sheets they believe could be of use in the
technology industry. Meanwhile, scientists in San Diego and South
Carolina developed nano-scale structures that can function as electrical switches."

It identifies 3 types of potential investments:

" Companies pursuing nanotechnology
can broadly be broken into three distinct divisions, each in a
different part of the value chain, each with its own distinct time line
for commercialization.

The first rung is comprised of companies developing nanomaterials,
the raw materials for finished products. This rung attracts the largest
volume of startups making it perhaps the riskiest place for investors.

Nordan says he sees more promise in companies developing so-called
intermediate products such as memory chips and microprocessors in the
electronics sector and fabrics and coatings for consumer and industrial
products.

The third rung — finished products that incorporate nano-enabled
chips, fabrics and coatings — is an area for the most-patient
investors. From 2010 onwards, Lux expects nanotechnology will become
commonplace in manufactured goods."
