Scientists at the Institute of Bioengineering and Nanotechnology (IBN), the world's first bioengineering and nanotechnology research institute, have developed a new genetic engineering technique that promises safer stem cell therapy for cancer patients.

A designer metamaterial has shown it can engineer emitted "blackbody" radiation with an efficiency beyond the natural limits imposed by the material's temperature.

Neben vielen anderen Anwendungsmoeglichkeiten koennen Nanoroehren zur Reinigung von kontaminiertem Wasser eingesetzt werden. Viele wasserverunreinigende Stoffe haben eine hohe Affinitaet fuer Kohlenstoffnanoroehren. Deshalb koennen Schadstoffe aus kontaminiertem Wasser entfernt werden, indem sie durch dieses Material gefiltert werden.

Integrating biological molecules or even complex molecular machines with man-made nanoelectronic devices is one of the ultimate goals of bionanotechnology. Already there is a growing community of researchers interested in this area of bio/nano integration where biological components are interfaced with inorganic nanomaterials to create new devices and systems that combine the desirable properties of each system. One particular nanomaterial used in this kind of research are carbon nanotubes (CNTs). Scientists now report the integration of a CNT transistor with olfactory receptor proteins. The ultimate goal of this type of research is to transfer the sensing properties of biological molecular systems to artificial electronic devices.

Renaissance architects demonstrated their understanding of geometry and physics when they built whispering galleries into their cathedrals. These circular chambers were designed to amplify and direct sound waves so that, when standing in the right spot, a whisper could be heard from across the room. Now, scientists at the University of Pennsylvania have applied the same principle on the nanoscale to drastically reduce emission lifetime, a key property of semiconductors, which can lead to the development of new ultrafast photonic devices.

Researchers from UCLA and Japan have designed a synthetic synapse for use in computing equipment that mimics the function of synapses in the human brain.

University of Wisconsin-Madison materials science and engineering researchers have introduced innovations that could make possible a wide range of new crystalline materials. They describe a new approach for using thin sheets of semiconductor known as nanomembranes.

Researchers at the SPring-8 Photon Science Research Division are developing a range of imaging tools to reveal the remarkable mechanism of bacterial locomotion.

Currently, when adult stem cells are harvested from a patient, they are cultured in the laboratory to increase the initial yield of cells and create a batch of sufficient volume to kick-start the process of cellular regeneration when they are re-introduced back into the patient. The process of culturing is made more difficult by spontaneous stem cell differentiation, where stem cells grown on standard plastic tissue culture surfaces do not expand to create new stem cells but instead create other cells which are of no use in therapy. New findings show that nanoscale patterning is a powerful tool for the non-invasive manipulation of stem cells. Their facile fabrication process employed, a range of thermoplastics that can be processed with exquisite reproducibility down to 5 nm fidelity using injection moulding approaches, offers unique potential for the generation of cell culture platforms for the up-scale of autologous cells for clinical use.

Modified metals that change colour in the presence of particular gases could warn consumers if packaged food has been exposed to air or if there's a carbon monoxide leak at home. This finding could potentially influence the production of both industrial and commercial air quality sensors.

New nanotechnology-based treatments, including nerve tissue engineering that draws on the limb-regrowing ability of the axolotl, and techniques for targeted attacks on ovarian and lung cancer, were discussed at a major nanomedicine conference in Sydney last week.

Avo Photonics, Inc., a specialist in opto-electronic design, packaging, and manufacturing, has been acquired by Halma, p.l.c., a leading safety, health and sensor technology group based in the United Kingdom. Avo will join Halma's global Photonics Division.

The combination of transmission electron microscopy and electron energy-loss spectroscopy allows for the study of surface plasmon resonance in nanostructures.

Researchers design a self-assembling material that can house other molecules.

Buckyballs can be converted into graphene quantum dots by heating them on a ruthenium substrate.

NanoBio Corporation announced today that data from its ferret influenza vaccine study of NB-1008 have been published in the July 2011 issue of Clinical Vaccine Immunology.

Among many potential applications, carbon nanotubes are great candidate materials for cleaning polluted water. Many water pollutants have very high affinity for carbon nanotubes and pollutants could be removed from contaminated water by filters made of this nanomaterial, for example water soluble drugs which can hardly be separated from water by activated carbon.
