Researchers have to place objects under study on suitable substrates to obtain a strong enhancement of electromagnetic radiation emitted by single molecules. A simple and cheap method to fabricate substrates for SERS spectroscopy has been discovered at the Institute of Physical Chemistry of the Polish Academy of Sciences. A key role in substrate fabrication play spherical gold aggregates - flower-like micrometer-sized spheres.
The Howard Hughes Medical Institute, the Max Planck Society and the Wellcome Trust announced today that they are to support a new, top-tier, open access journal for biomedical and life sciences research.
Pupils aged 12-14 years old from Kingham-Hill School, Marlborough School, The Oxford Academy, and Oxford High School, took part in the event where they got to learn about the basic science behind applications of nanotechnologies and investigate the properties of nanoscale materials.
A research group at the University of Bayreuth has developed a process which opens an avenue for the production of new, completely miscible nanocomposites. These materials represent an extremely varied potential for technological innovations.
Tiny metallic particles produced by University of Adelaide chemistry researchers are bringing new hope for the production of cheap, efficient and clean hydrogen energy. The researchers are exploring how the metal nanoparticles act as highly efficient catalysts in using solar radiation to split water into hydrogen and oxygen.
A recent Kavli Futures Symposium focused on the progress, and promise, of evolving biological functions in the lab. Now, 3 Symposium participants discuss this remarkable research, and how it's drawing together diverse scientific fields.
Engineers at Oregon State University have discovered a way for the first time to create successful "CIGS" solar devices with inkjet printing, in work that reduces raw material waste by 90 percent and will significantly lower the cost of producing solar energy cells with some very promising compounds.
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.
