- World Gold Council Research Paper Demonstrates Important Applications
in Development Using Gold Nanoparticles
World Gold Council (WGC) has today published 'Gold for Good: Gold and
nanotechnology in the age of innovation', a research paper detailing new
scientific and technological innovations using gold. The report, which was
produced in conjunction with Cientifica Ltd, the world's leading source of
global business and investor intelligence about nanotechnologies,
demonstrates how gold nanoparticles offer the potential to overcome many of
the serious issues facing mankind over the coming decades.
Gold nanoparticles exhibit a variety of unique properties which, when
harnessed and manipulated effectively, lead to materials whose uses are both
far-ranging in their potential and cost effective. This report explores the
many different applications that are being developed across the fields of
health, environment and technology.
Trevor Keel, Nanotechnology Project Manager at World Gold Council said:
"The opportunities and possibilities identified in this report are just a
subset of the amazing scope to use gold in the era of nanotechnology. As a
readily available and well understood material, gold nanoparticles are ideal
for use in a vast array of applications that improve our lives. WGC is
looking to promote and invest in the development of gold-based innovations
through Innovations Partnerships, so that the full benefits of gold
nanotechnology can be realized."
Tim Harper, founder of Cientifica Ltd, said:
"Over the last decade, almost $50 billion of government funding has been
invested into nanotechnologies, and this investment is now starting to bear
fruit with a steady stream of commercially viable nanotechnologies which are
positively impacting human health, the environment and technology. This paper
demonstrates the many varied applications in which gold nanotechnology can
improve society's standard of living."
Health: Gold has a long history in the biomedical field stretching back
almost five thousand years. However the dawn of the 'nano-age' has really
broadened the potential of gold in biomedical applications and today, gold
nanoparticles are being employed in entirely novel ways to achieve
Tumor targeting technologies which exploit gold's inherent
bio-compatibility are being developed to deliver drugs directly into
cancerous tumours. Additionally, simple, cost effective and sensitive
diagnostic tests are being developed for the early detection of prostate and
Environment: Environmental concerns have never been more prominent -
energy and clean water scarcity, global warming and pollution are all major
issues that need to be addressed. Gold nano-particle based technologies are
showing great promise in providing solutions to a number of environmentally
important issues from greener production methods of the chemical feedstocks,
to pollution control and water purification.
Gold-based catalysts are being developed that can effectively prevent the
release of highly toxic forms of mercury into the atmosphere, the reduction
of chemicals from green feedstock, and also for water purification and
contaminant detection. In addition, gold is being used in meeting the
challenge of constructing cost effective and efficient fuel cells, a key
'clean-energy' technology of the future.
