How will nanotechnology contribute to prevention, diagnosis, and treatment of diseases? Nanoelectronics are evolving increasingly toward cell dimensions, even molecules, say Kris Verstreken, MD, PhD and Hanne Degans, PhD, Imec, noting that the interaction of electronic and biological functions can bring about new fields for biomedical electronics.
A prototype implantable eye pressure monitor for glaucoma patients is believed to contain the first complete millimeter-scale computing system. And a compact radio that needs no tuning to find the right frequency could be a key enabler to organizing millimeter-scale systems into wireless sensor networks.
Research conducted in the Kanzius/Curley Lab at The University of Texas M.D. Anderson Cancer Center shows that, when non-human subjects are exposed to 10 minutes of nonionizing RF radiation followed by 36 hours of treatment using targeted gold nanoparticles, the Kanzius RF machine and nanoparticles create an effective formula for controlling pancreatic cancer cells.
Researchers at MIT and Brigham and Women’s Hospital have shown that they can deliver the cancer drug cisplatin much more effectively and safely in a form that has been encapsulated in a nanoparticle, targeted to prostate tumor cells and activated once it reaches its target. The results from lab cells were confirmed in mice.
Research by engineers and cancer biologists at Virginia Tech (Virginia Polytechnic Institute and State University) indicate that using specific silicon microdevices might provide a new way to screen breast cancer cells' ability to metastasize.
The World Gold Council (WGC) revealed that a phase 1 clinical trial by CytImmune Sciences of a unique nanomedicine was sucessful. The medicine uses gold nanoparticles as the core of a delivery system for tumour-targeted drug delivery.
Researchers with the U.S. DOE's Berkeley Lab have been able to fabricate nanochannels that are only 2nm in size, using standard semiconductor manufacturing processes. These channels function differently than their larger counterparts.
Animals like dolphins and pilot whales are known to have anti-fouling skins. Researchers from A*STAR's Industrial Consortium On Nanoimprint (ICON) are using nanotechnology to mimic this, creating synthetic, chemical-free, anti-bacterial surfaces. The surfaces can reduce infections caused by pathogens such as S. aureus and E. coli and can be used on common plastics, medical devices, lenses and even ship hulls.
Researchers at Delft University of Technology and Oxford University announced a new type of nanopore device that could help in developing fast and cheap genetic analysis. The new research demonstrates a simple method to implant the pore-forming proteins into a robust layer in a silicon chip.
Magnetic fluid hyperthermia (MFH) is a promising new cancer treatment that heats cells inside tumors to kill them. Magnetic nanoparticles are injected into the body intravenously and diffuse selectively into cancerous tissues. Add a high-frequency magnetic field, and the particles heat up.
The projects are focused on the three main subfields of nanotech in medicine: diagnostics, targeted delivery systems and regenerative medicine. Eight projects, involving 46 partners from 10 countries, will be funded by EuroNanoMed partners.
A nest for nanotubes may help magnetic resonance imaging become better than ever at finding evidence of disease. Scientists at Rice University and other Texas Medical Center institutions and colleagues in Colorado, Italy and Switzerland have discovered a way to trap contrast agents inside a silicon particle.
Yale University researchers have covalently re-engineered the cell wall of Staphylococcus aureus, the most common cause of a staph infection. James W. Nelson, Alexander G. Chamessian, Patrick J. McEnaney et al published the research findings in American Chemical Society's Journal of Chemical Biology, in "A Biosynthetic Strategy for Re-engineering the Staphylococcus aureus Cell Wall with Non-native Small Molecules."
Plasmonic nanobubbles, generated around gold nanoparticles with a laser pulse, can detect and destroy cancer cells in vivo by creating tiny, shiny vapor bubbles that reveal the cells and selectively explode them. The nanobubbles have been tested in theranostics with live human prostate cancer cells, without harming the animal host.
Researchers at Oregon State University have the successful loading of biological molecules onto “nanosprings” -- a type of nanostructure that has gained significant interest in recent years for its ability to maximize surface area in microreactors.
NanoInk’s NanoFabrication Systems Division instruments, most notably the NLP 2000 System, have now been proven to enable applications related to micropatterning of polyethylene glycol (PEG)-based hydrogel and UV-curable polymer.
NanGenex Inc., Proprietary NanoSolution Technology Platform Company, presents its latest GMP-compliant benchtop and pilot plant reactor for the industrial scale production of NanoActive nanoparticles.
Cerulean Pharma summarizes findings on its nanopharmaceutical CRLX101 and docetaxel nanopharmaceutical CRLX288. The cancer therapy nano medicines have shown promise for stabilizing cancer in advanced/progressive disease and mitigating chemotherapy side effects, respectively.
NC State researchers developed a method for predicting the ways nanoparticles will interact with biological systems, including the human body. Their work could have implications for improved human and environmental safety in the handling of nanomaterials, as well as apps for drug delivery.
electronica 2010 will showcase a prosthetic leg that moves in response to the wearer's thoughts. The technology was developed by American biophysicist Hugh Herr, a professor at MIT, Freescale Semiconductor and the Fraunhofer Institute for Manufacturing Engineering and Automation IPA.
