Surface plasmons are collective oscillations of free electrons that occur at the interface between a metal and a dielectric medium, such as air or glass. These oscillations are coupled with ...

The basis of SPR analysis is the measurement of changes in the resonance angle as molecules bind to or dissociate from the metal surface. This change can be detected and quantified, providing detailed ...

Researchers from CIC nanoGUNE, in collaboration with the Donostia International Physics Center (DIPC) and the Center for Materials Physics (CFM), have experimentally observed and theoretically ...

In a study published in Analytical Chemistry, a research team led by Wang Junfeng from the Hefei Institutes of Physical Science of the Chinese Academy of Sciences has developed a novel immobilization ...

Surface plasmons are collective oscillations of free electrons at the conductor-dielectric interface, driven by an external electromagnetic field. These waves, known as surface plasmon waves (SPWs), ...

How It Works: Surface Plasmon ResonanceMany functional proteomic technologies require time-consuming labeling steps and still produce little more than yes or no answers as to whether proteins interact ...

The nano-IR imaging set-up for studying the moiré graphene lattice. (Courtesy: G Ni) Researchers at the University of California at San Diego (UCSD) are the first to have used infrared nano-imaging to ...

Highly efficient controlling the individual atomic migration is the basis of the modern atomic manufacturing. Although one-by-one atom migration can be realized precisely by STM technique, such a ...

How could we noninvasively distinguish between healthy and cancerous tissue? And how could we increase the speed of wireless communications? These two seemingly unrelated questions may share the same ...
