All smoothed out - hydroxyl radicals remove nanoscopic irregularities on polished gold surfaces

The precious metal gold is the material of choice for many technical applications because it does not corrode - and because it also has interesting electrical, magnetic, and optical properties. In these applications, it is extremely important that the surface of the gold be completely clean and smooth. However, conventional processes not only 'polish' away the undesirable irregularities, but also attack the gold surface.

Nanoprobes hit targets in tumors, could lessen chemo side effects

A variety of nanoparticles have shown to be effective in delivering cancer drugs more directly to tumor cells, mitigating the damage to nearby healthy cells. Now, researchers from Purdue University have demonstrated that these nanoparticles are getting their drug payloads to the correct intracellular compartments.

Nanosystems capture and destroy circulating tumor cells

Just as fly paper captures insects, a pair of nanotechnology-enabled devices are able to grab cancer cells in the blood that have broken off from a tumor. These cells, known as circulating tumor cells, or CTCs, can provide critical information for examining and diagnosing cancer metastasis, determining patient prognosis, and monitoring the effectiveness of therapies.

Nanoparticle cocktail targets and kills tumors

A team of researchers from two of the National Cancer Institute's Centers of Cancer Nanotechnology Excellence have teamed up to develop a 'cocktail' of different nanometer-sized particles that work in concert within the bloodstream to locate, adhere to and kill cancerous tumors.

Key piece of puzzle sheds light on function of ribosomes

When ribosomes produce protein in all living cells, they do so through a chemical reaction that happens so fast that scientists have been puzzled. Using large quantum mechanical calculations of the reaction center of the ribosome, researchers at Uppsala University in Sweden can now provide the first detailed picture of the reaction.
