Latest Surface plasmon resonance Stories
At the heart of the immune system that protects our bodies from disease and foreign invaders is a vast and complex communications network involving millions of cells, sending and receiving chemical signals that can mean life or death.
The physical phenomenon of plasmon resonances in small metal particles has been used for centuries.
Researchers at Chalmers University of Technology have built a very simple nanoantenna that directs red and blue colors in opposite directions, even though the antenna is smaller than the wavelength of light.
The world's first three-dimensional plasmon rulers, capable of measuring nanometer-scale spatial changes in macrmolecular systems, have been developed by researchers with the U.S. Department of Energy (DOE)'s Lawrence Berkeley National Laboratory (Berkeley Lab), in collaboration with researchers at the University of Stuttgart, Germany.
Nanoparticles of silver are being found increasingly in the environmentâ€”and in environmental science laboratories.
