Peptide nanotubes for highly sensitive pathogen sensors chips
peptide_nanotubesPosted: Dec 2nd, 2008
Miniaturizing traditional laboratory assays to automated lab-on-a-chip devices holds tremendous potential for enabling multiplex, efficient, cost-effective and accurate pathogen sensing systems for both security and medical applications. These sensors could be used to detect bacteria such as E. coli and Salmonella, but also other pathogens that could be used for bioterrorism. Traditional identification methods required time intensive cell culturing processes but novel pathogen sensors based on nanomaterials are promising vastly improved and speedy detection technologies. A recent example is a label-free sensor chip assembled from peptide nanotubes... nanotechnology article
Artificial nano swimmers
nanoswimmerPosted: Dec 1st, 2008
Advances in micro- and nanoscale engineering have led to various mobile devices that either can move on solids or swim in fluids. Researchers are applying various strategies to designing nanoscale propulsion systems by either using or copying biological systems such as the flagellar motors of bacteria or by employing various chemical reactions. Many of these approaches are fairly complex and not necessarily suited for large-scale deployment in practical applications. Scientists have theorized about simpler designs for mechanical swimmers that avoid the complexities of biological mechanisms and use very few degrees of freedom. Researchers in Spain... nanotechnology article
Nanotechnology gets a grip
nanogripperPosted: Nov 26th, 2008
Nanotechnology researchers are actively working on the beginnings of various nanorobotic systems that one day could lead to automated, assembly-line type nanofabrication processes. Last year we reported on a nanogripper, a kind of a robotic 'hand' some ten thousand times smaller than a human hand. This 'pick-and-place' device used a silicon gripper which was controlled by a nanorobotic arm and was capable of picking up a carbon nanofiber and fix it onto the tip of an atomic force microscope cantilever. One of the problems that is vexing researchers is that the nanoscale miniaturization of these grippers comes at the cost of reduced strength -... nanotechnology article
Next generation nanotechnology computer memory made of graphene
nanocablePosted: Nov 25th, 2008
Experiments with graphene have revealed some fascinating phenomena that excite researchers who are working towards molecular electronics. It was found that graphene remains capable of conducting electricity even at the limit of nominally zero carrier concentration because the electrons don't seem to slow down or localize. This means that graphene never stops conducting. Taking advantage of the conducting properties of graphene, researchers now have described how graphene memory could potentially be used as a new type of memory that could significantly exceed the performance of current state-of-the-art flash memory technology. Their results show... nanotechnology article
A British take on nanotechnology risks
union_jackPosted: Nov 24th, 2008
The UK's Royal Commission on Environmental Pollution in a new report clearly states that it found no evidence of harm to health or the environment from nanomaterials but it believes that the pace at which such new nanomaterials are being developed and marketed is beyond the capacity of existing testing and regulatory arrangements to control the potential environmental impacts adequately. A major conclusion of the report is that nanomaterials are hugely variable in their nature. They are not a uniform class of materials, and attempts to regulate or legislate solely on the basis of their size or how they are made are misguided. It is the functionality... nanotechnology article
