Gold nanoparticles and tea compound treat prostate cancer with fewer side effects than chemotherapy
Currently, large doses of chemotherapy are required when treating certain forms of cancer, resulting in toxic side effects. The chemicals enter the body and work to destroy or shrink the tumor, but also harm vital organs ...
World's most sensitive dark matter detector set up
The world's most sensitive dark matter detector settled into a new home Friday in an old U.S. gold mine.
Guyana suspends gold, diamond mining permits
The South American country of Guyana said it had suspended the granting of new permits to mine for gold and diamonds in rivers because of concerns over widespread pollution.
Nanostructured sensors power novel cancer detection system
(Phys.org) -- Using a sensor made of densely packed carbon nanotubes coated with gold nanoparticles, a researcher team headed by James Rusling of the University of Connecticut has developed a low-cost microfluidic device ...
Argentina court upholds glacier protections against mining
Argentina's supreme court has upheld key articles of a law aimed at protecting glaciers, despite a legal challenge from mining companies, including Canadian giant Barrick Gold.
Researchers propose gold and DNA based dark matter detector
Not-so-precious: Stripping gold from AFM probes allows better measurement of picoscale forces
(Phys.org) -- Gold is not necessarily preciousat least not as a coating on atomic force microscope (AFM) probes.
Researchers find gold nanoparticles capable of 'unzipping' DNA
New research from North Carolina State University finds that gold nanoparticles with a slight positive charge work collectively to unravel DNA's double helix. This finding has ramifications for gene therapy ...
Study improves understanding of surface molecules in controlling size of gold nanoparticles
North Carolina State University researchers have shown that the "bulkiness" of molecules commonly used in the creation of gold nanoparticles actually dictates the size of the nanoparticles with larger ...
Atomic structure of nanoparticles brought under control
Nanotechnologists are control freaks. They want to exploit the properties of materials at the ultimate level - the atoms.
Imaging nanoporous metals with beams of electrons provides deep insights into unusual optical properties
Gold is usually thought of as being a shiny metal however, in its porous form, gold actually appears dull and black. The surfaces of nanoporous gold are rough and the metal loses its shine. Michel Bosman ...
Researchers love triangles: Shaped catalysts spark longer, faster-growing, rule-breaking nanowires
A research team at Case Western Reserve University has found that gold catalysts shaped in the form of a cube, triangle, or other higher order structures grow nanowires about twice as fast and twice as long compared to wires ...
Under the influence of magnetic drugs
(Phys.org) -- For more than three decades scientists have been investigating magnetic nanoparticles as a method of drug delivery. Now by combining three metals - iron, gold and platinum - pharmacists at the ...
The finest gold dust in the world
(Phys.org) -- Scientists at the Vienna University of Technology found a method to locate single gold atoms on a surface. This should pave the way to better and cheaper catalysts.
