A research team led by University at Buffalo chemists has used synchrotron light sources to observe the electron clouds on the surface of graphene, producing a series of images that reveal how folds and ripples in the remarkable material can harm its conductivity.
Using a new sample holder, researchers at the University of Gothenburg, Sweden, have further developed a new method for imaging individual cells. This makes it possible to produce snapshots that not only show the outline of the cell's contours but also the various molecules inside or on the surface of the cell, and exactly where they are located, something which is impossible with a normal microscope.
In 2008, a team of investigators at Stanford University's Center for Cancer Nanotechnology Excellence demonstrated that they could use a technique known as nanoparticle-aided Raman spectroscopy to look at microscopic structures, including nascent tumors, deep inside the body. That team has now conducted extensive preclinical tests and shown that the gold nanoparticles can be safely administered into the colon and used with a Raman endoscope to image the inside of the large intestines.
Precision measurement in the world of nanoparticles has now become a possibility thanks to scientists at the University of California-Santa Barbara (UCSB). The UCSB research team has developed a new instrument capable of detecting and analyzing individual nanoparticles with diameters as small as a few tens of nanometers.
Research led by scientists from the California Institute of Technology has shown that a new generation of microchips developed by the team can quickly and inexpensively assess immune function by examining biomarkers - proteins that can reflect the response of the immune system to disease - from single cells.
A team of investigators from Stanford University has developed an improved imaging method using fluorescent carbon nanotubes that create color images centimeters beneath the skin with far more clarity than conventional dyes provide. For a creature the size of a mouse, a few centimeters makes a great difference.
The Institute of Materials Research and Engineering (IMRE), a research institute of Singapore's Agency for Science, Technology and Research (A*STAR), hosts the first AtMol workshop for the world's experts in the advanced tools needed to build a molecule-sized chip.
Physicists working at the University of California, Santa Barbara and the University of Konstanz in Germany have developed a breakthrough in the use of diamond in quantum physics, marking an important step toward quantum computing.
The ENIAC Joint Undertaking launched today its new Call for proposals, boosted by the strong participation of the funding authorities who committed in 2011 grants up to 175 million euros, an increase of 100% over the previous year.
Today, Open Access publisher InTech launches its new groundbreaking Journal, the Nanomaterials and Nanotechnology Journal, available to access online, download free of charge, and submit material without publishing fees.
Saeulen aus Galliumarsenid sind eine Alternative zu Schichten, denn sie wachsen auch auf Silizium in guter Qualitaet. Forscher des Paul-Drude-Instituts konnten jetzt den Nachweis erbringen, dass der haeufig verwendete Goldkatalysator die Eigenschaften der Saeulen empfindlich stoert.
