Professor Jonathan Coleman, a Science Foundation Ireland (SFI)-funded researcher from Trinity College who has achieved international success in the area of nanostructures, was today announced as the 'Science Foundation Ireland Researcher of the Year' for 2011.
This event is the fourth in a four-part series of public forums and candid conversations with top science and medical researchers discussing policy topics of global concern, offered at the American Association for the Advancement of Science (AAAS).
Purdue University scientists have developed a method for stacking synthetic DNA and carbon nanotubes onto a biosensor electrode, a development that may lead to more accurate measurements for research related to diabetes and other diseases.
Businesses in the nanotechnology field may even forget the word nano. To secure success they have to focus on solving customers' problem and better communicate business opportunities that nanotechnologies may bring.
In nature, the strength of mother-of-pearl is a key to survival for some shellfish. Now a team at the University of South Carolina has posited an explanation for the unusual resilience that this important defensive shield shows in the face of predatory attacks.
An investigation by a group of Thai researchers has demonstrated that Caveolin-1 (Cav-1) plays an important role in the migration and invasion of human lung cancer cells and that these effects are regulated by cellular reactive oxygen species (ROS).
Upconversion emission materials are ideal for bioimaging due to its effectiveness as contrast agents for the detection of cancer cells, more so when the background emission of non-cancerous tissues can be minimised. These materials could be used as biomarkers for luminescent labeling of cancerous cells. Researchers have now succeeded in developing an efficient upconversion process in nanoparticles, ensuring a broad tunability of light emission that could be used in imaging applications.
Hundertprozentige Sicherheit gibt es auf dem Gebiet der Quanteninformation, der Signaluebertragung mit einzelnen Lichtteilchen. Nun haben Wissenschaftler einen winzigen Lichtspeicher aus Diamant hergestellt, mit dem sie die Erzeugung der benoetigten einzelnen Lichtteilchen deutlich steigern konnten.
