Fabrication and characterization of a surface plasmon resonance based fiber optic sensor for the detection of melamine using molecular imprinting are reported by Shrivastav et al. from Physics Department of Indian Institute of Technology in Delhi (February 2015).

Putting a new spin on plasmonics

Researchers at Aalto University have discovered a novel way of combining plasmonic and magneto-optical effects. Magnetic nanoparticles arranged in arrays put a twist on light: depending on the distance between the nanoparticles, one frequency of light (visible to the human eye by its colour) resonates in one direction; in the other direction, light (induced by […]

Plasmon-Assisted Audio Recording

Researchers at the University of Illinois at Urbana-Champaign have successfully recorded optically encoded audio onto a plasmonic nanostructure that is non-magnetic. This is considered to be the first ever recording of such an audio. This type of recording could be used for archival storage and informational processing.

DNA does design: 3D plasmonic photonic crystals are the fi...

Jan 14, 2015 by Stuart Mason Dambrot (Phys.org)—As biotechnology and nanotechnology continue to merge, DNA-programmable methods have emerged as a way to provide unprecedented control over the assembly of nanoparticles into complex structures, including customizable periodic structures known as superlattices that allow fine tuning the interaction between light and highly organized collections of particles. Lattice […]
