Center of Biofunctional Nanomaterials in San Sebastian (Spain), Valery Pavlov and his co-workers are undertaking research in the area of the design and preparation of new biomaterials for such applications. They report on a new analytical approach in which the enzymatic generation of quantum dots can be applied to the detection of enzymatic activities inChemistry - A European Journal ("Analytical Applications of Enzymatic Growth of Quantum Dots").
Nanotechnology is the subject of much hype, claim and counter-claim. To many people, nanotechnology is still a technology of the future, associated more with science fiction than with fact.
The military have been quicker than most to appreciate the potential of nanotechnology. More money is being spent on nanotechnology research for military applications than for any other area. The idea that nanotechnology could lead to lighter weight, smarter devices for soldiers in the field, uniforms that offer ballistic and other protection, and more deadly weaponry, has proved irresistible. This article examines some of the military problems for which nanotechnologies are offering new solutions.
In this article, Jurgen Altmann discusses the potential military applications of nanotechnlogy, and looks at the ethical concerns involved. He describes a framework for an ethical assessment, and follows this with a discussion of the current system of preventive arms control. He asks whether nanotechnology will lead to a revolutionary change in this international system.
Japan has long been recognised as a world leader and key player in global advances in science and technology and recent investment and progress is establishing the country’s place in the global nanotechnology arena.
Having early access to accurate and reliable diagnostic information is a crucial part of medical treatment; it can improve the prognosis for patients by identifying diseases or conditions at a much earlier and more treatable stage; it can provide information on the ongoing effectiveness of therapies; and it can reduce the costs for increasingly cash-strapped healthcare systems by reducing the time spent in expensive hospital stays. For many patients, for example those with conditions like diabetes, it can be an important part of daily routine and essential self-testing.
In every issue we bring you an interview with a leading opinion maker from the world of nanotechnology. Ottilia Saxl talks with CEA-LETI Director Laurent Malier about his burning ambitions.
Nanoparticles for new vaccines, nanostructures on credit cards, microscopy and spins are just some of the range of research projects currently underway at institutions across Switzerland.
Laser scanning microscopes are at the forefront of scientific research. Advances in microscopy are already enabling researchers to image live cells and tissues in three dimensions, but there are improvements to be made.
Diabetes has reached epidemic levels in the developed world and the race is on to develop new tools to manage and treat the condition. From sensing devices no bigger than a human hair to implanting new glucose-regulating cells, Tania Saxl investigates the ultimate ambition to create an artificial pancreas.
...but who benefits?
“Prevention is better than cure” seems a simple enough statement, but how does it affect the future of medicine? Ottilia Saxl reports.
Until now, healthcare companies have made money by treating disease. So what is in it for those companies who go into the business of prevention? Intuition might say nothing, but let’s look at the possibilities in a little more depth.
New materials such as carbon nanotubes, nanowires, nanofibres, quantum dots and nanoparticles are being explored for their use as (nano) sensors. The potential of these materials for sensing has already been exploited in several industries ranging from security, health and environmental monitoring to automotive, agriculture and energy.
Below some potential industrial applications of nanotechnology enabled sensors are discussed.
