Researchers at Purdue University are using a rare type of electron microscope to see how structures like carbon nanotubes form at the atomic level, information that will be crucial for nanotechnology to find practical applications in computing, electronics and other areas.
Researchers at the University of Arkansas have found a way to create switching in nanoscale materials, opening the path to using these new properties for memory devices, nanomotors, nanoswitches or nanosensors.
Winston Patrick Kuo, DDS, MS, DMSc, post-doctoral researcher in the Department of Oral and Developmental Biology at the Harvard School of Dental Medicine, and colleagues tested nearly all the available commercial and "in-house" gene expression microarray platforms for cross-platform and cross-laboratory comparisons.
Researchers have created organic gel nanomaterials that could be used to encapsulate pharmaceutical, food, and cosmetic products and to build 3-D biological scaffolds for tissue engineering. Using olive oil and six other liquid solvents, the scientists added a simple enzyme to chemically activate a sugar that changed the liquids to organic gels.
Researchers at the University of California, San Diego have developed what they call a "Smart Petri Dish" that could be used to rapidly screen new drugs for toxic interactions or identify cells in the early stages of cancer circulating through a patient's blood.
Nanotechnology simulations show what experiments miss...Taking issue with the perception that computer models lack realism, Sandia National Laboratories researcher Eliot Fang told members of the Materials Research Society that simulations of the nanoscale provide researchers more detailed results - not less - than experiments alone.
Bombarding a carbon nanotube with electrons causes it to collapse with such incredible force that it can squeeze out even the hardest of materials, much like a tube of toothpaste, according to an international team of scientists. The researchers suggest that carbon nanotubes can act as minuscule metalworking tools, offering the ability to process materials as in a nanoscale jig or extruder.
University of Maryland chemistry professor John Fourkas and his group have developed a new technique that promises to make the mass production of complex plastic microstructures a routine, one-step process.
A team of researchers has achieved a long-sought scientific goal: using laser light to break specific molecular bonds. The process uses laser light, instead of heat, to strip hydrogen atoms from silicon surfaces. This is a key step in the manufacture of computer chips and solar cells, so the method could reduce their cost and improve their quality.
Imagine having computer memory so dense that a cubic centimeter contains 12.8 million gigabytes (GB) of information. Imagine an iPodTM playing music for 100 millennia without repeating a single song or a USB thumb-drive with room for 32.6 million full-length DVD movies.
Now all they need is a really, really small corkscrew. Like Lilliputian chemists, scientists have found a way to "cork" infinitesimally small nano test tubes. The goal is a better way to deliver drugs, for example, for cancer treatment. Scientists want to fill the teeny tubes with drugs and inject them into the body, where they will seek diseased or cancerous cells, uncork and spill their therapeutic contents in the right place.
Texas scientists have added one more trick to the amazing repertoire of carbon nanotubes "” the ability to carry electrical signals to nerve cells.
Engineers have created carpets made of tiny cylinders called carbon nanotubes to enhance the flow of heat at a critical point where computer chips connect to cooling devices called heat sinks, promising to help keep future chips from overheating.
Nanotechnology may one day help physicians detect the very earliest stages of serious diseases like cancer, a new study suggests. It would do so by improving the quality of images produced by one of the most common diagnostic tools used in doctors' offices "“ the ultrasound machine.
Using experimental data and simulations, researchers have identified key parameters that predict the outcome of nanoimprint lithography, a fabrication technique that offers an alternative to traditional lithography in patterning integrated circuits and other small-scale structures into polymers.
Researchers at the Georgia Institute of Technology have crafted tiny nanowires that generate electricity when they vibrate. Just like the quartz crystal in a watch, the zinc-oxide nanowires are piezoelectric, which means bending causes them to produce an electrical charge.
The emerging discipline of nanotechnology holds the promise of improving functional foods and the capability of delivering healthful food compounds to the body where it can utilize them best, according to the latest issue of Food Technology.
Researchers have developed "custom" nanoparticles that show promise of providing a more targeted and effective delivery of anticancer drugs than conventional medications or any of the earlier attempts to fight cancer with nanoparticles. The nanoparticles also have the potential to reduce side effects associated with chemotherapy.
Researchers at the Georgia Institute of Technology have found that by using gold nanorods, rather than nanospheres, they can detect malignant tumors hidden deeper under the skin and destroy them with lasers only half as powerful as before "“ without harming the healthy cells.
Researchers have developed a new process to make flexible, conducting "nano skins" for a variety of applications, from electronic paper to sensors for detecting chemical and biological agents. The materials combine the strength and conductivity of carbon nanotubes with the flexibility of traditional polymers.
