Graphene Plasmonics Beat the Drug Cheats
MANCHESTER, England, and MARSEILLE, France, Jan. 17, 2013 — A simple optical system using graphene plasmonics can potentially see a single molecule and can analyze its composition within minutes. The advance could lead to more sensitive drug testing of professional athletes.
DNA Origami Nanolenses to Visualize Single Molecules
BRAUNSCHWEIG, Germany, Nov. 2, 2012 — Overlapping plasmonic fields, created by positioning two gold nanoparticles on DNA origami, form a nanolens that acts as a nanoantenna capable of enhancing the fluorescent emission of a single molecule, researchers in Germany report.
Molecular Machine Opens and Closes in Response to Light
May 1, 2007 — Equipped with tools that can manipulate single molecules, researchers may be able to construct molecular robotic devices for numerous applications. Although a number of groups have produced tools with such potential, until recently none had...
Nanoholes Improve Single-Molecule Analysis
Mar 1, 2003 — Researchers at Cornell University in Ithaca, N.Y., have developed a nanostructured sample holder that enables the analysis of single molecules at realistic concentrations. The device, which features arrays of tiny holes in a metal film, has...
