Molecular Nanoelectronics 2008-06-08 08:58:01 Organic molecules have also been shown to have the necessary properties to be used in electronics and a single atom transistor was even demonstrated recently. Devices made of molecular components would be much smaller than those made by existing silicon technologies and ultimately offer the smallest electronics theoretically possible without moving into the realm of subatomic particles. The issues Read more:Molecular
LONG TERM POSSIBILITIES 2008-04-17 19:11:54 You may have read in the popular press of an imminent future, with tiny submarines patrolling our bodies, stitching up damaged tissue, zapping an occasional cancer cell or invading virus or switching off an errant gene; nanorobots weaving extensions to our brains to enhance our intelligence; desktop machines that can make you a diamond ring; a table that will transform into a chair at the flick of

MOLECULAR MACHINES 2008-04-17 19:11:54 Then comes the second big idea, getting these molecular machines to make copies of themselves, which then make copies of themselves, which then make copies, and so on. This would lead to exponential growth of tiny machines that could then be used to construct macro scale objects from appropriate molecular feedstock’s, and with no wastage. In theory, large, complex structures could be built with
SOURCES IN VARIOUS OTHER COUNTRIES 2008-04-17 19:11:54 - EC European Consortium on Nanomaterials Network on Nanoelectronics "Phantoms", lead by the Inter-university Microelectronics Center (IMEC), Liuven, Belgium - Germany Network of competency in nanotechnology, 6 centers territorially distributed Institute of Nanotechnology, Karlsruhe - France Institute for Micro and Nanotechnologies (
Examples of centers and networks primarily supported by government sources 2008-04-17 19:11:54 While single and smaller group investigators do most of the nanoscale R&D, the larger research centers play an essential role in the development of major topics and establishing of partnerships. Centers providelong-term coherence, interdisciplinary, and a meeting place of people with multiple expertise and tools covering the various needs of nanotechnology development.

MAGNETIC RAM 2008-06-23 05:02:30 There are several flavors of MRAM and one has seen limited commercial use already. MRAM offers a number of attractive features, including the fact that it is non-volatile, enabling devices such as a PC or mobile phone to boot up in little or no time. Several companies are working on MRAM technologies, and suggestions are that while the data densities might not be as good as with other technologies
HARD DRIVES AND TAPES 2008-06-23 05:01:31 Hard drives currently on the market for PCs have capacities in the tens of gigabytes and data densities of a few tens of gigabytes per square inch with 100 Gbits/sq. in. expected in the next generation. The use of magnetic nanoparticles offers the potential of terabyte drives, as does the patterned media approach being pursued by IBM and General Electric. Interestingly, this latter approach is bei Read more:HARD DRIVES
MEMORY AND STORAGE 2008-06-23 04:59:11 We have noted that part of the difficulty in creating processors with nanotubes or molecular electronics relates to complexity. Data storage structures are far less complex than processors and many new technologies are converging on this area, promising commercialization in five years or less. Information storage requirements continue to grow but vary in nature from one application to another and
NANO IN SCIENCE 2008-07-08 07:37:34 Nanoscience will have a huge impact on the biological sciences (and thus medicine and agriculture, for example) in the long term, and a significant impact in the short and medium terms, simply by virtue of our growing ability to work on the scale of biological systems. The impact will work both ways too—nature has evolved, over billions of years, mechanisms with a complexity, effectiveness and e
NANO IN LIFE SCIENCE 2008-07-08 07:34:45 This is the area where nanotech has been most severely hyped, as a technology that will cure cancer, eliminate infections, enhance our intelligence and make us immortal. It is also the area where the bounds of nanotechnology are most blurred. This is because nature’s technology operates predominantly at the nanoscale. However our knowledge of the chemical structure of DNA and the proteins it cod
Display technologies 2008-07-08 07:32:29 The hang-on-your-wall television (at an affordable price) has been awaited for a long time and nanotechnology may finally bring it into your home. Carbon nanotubes are excellent field emitters, i.e. they can be made to produce a stream of electrons, as does the electron gun in your bulky cathode ray tube TV. Several groups are promising consumer flat screens based on nanotubes by the end of 2003 o Read more:Display

Optical Switching 2008-07-08 07:31:16 Communications networks will no doubt continue to grow in capacity for some time as more people come to expect more from the Internet. Nanotechnology, or more specifically soft lithography (or nanoimprinting) is already being used in the production of sub-wavelength optical components. This is an area well worth keeping an eye on (the US optical switching market is expected to grow from $1.6 billi Read more:Optical

SPMs for Storage 2008-07-08 07:30:18 Several variations on using scanning probe microscopes for data storage are being pursued, the three main varieties being based on using scanning tunneling microscopes on phase change materials (akin to the way Cd's work), magnetic force microscopes, and atomic force microscopes. This latter approach, which makes indentations in a polymer, has received the most publicity through IBM's Millipede pr

NANO IN DRUG DELIVERY 2008-08-04 10:56:48 Drug delivery is an area that is already showing significant impact from nanotechnology, with some approaches using nanoparticles or nanocapsules to deliver drugs through the skin, lungs, stomach and eyes already in clinical trials and many more in preclinical trials.The advantages of these approaches are varied, such as increased solubility, resistance to gastric enzymes (offering oral delivery o
Nanostructured Materials 2008-08-04 10:54:08 Nanostructured materials, coupled with liquid crystals and chemical receptors offer the possibility of cheap, portable biodetectors that might, for instance, be worn as a badge. Such a badge could change color in the presence of a variety of chemicals and would have applications in hazardous environments.

Nanoparticles and nanowires 2008-08-04 10:52:02 Another boon to bioanalysis looks set come from the attaching of nanoparticles to molecules of interest. Nanoparticles small enough to behave as quantum dots can be made to emit light at varying frequencies. If you can get particles that emit at different frequencies to attach to different molecules, you can spectroscopically determine the presence of many different molecules at the same time in a
