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 (—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 […]

Myungjae Lee et al., report a Highly Tunable and Fully Biocompatible Silk  Nanoplasmonic Optical Sensor. Novel concepts for manipulating plasmonic resonances and the biocompatibility of plasmonic devices offer great potential in versatile applications involving real-time and in vivo monitoring of analytes with high sensitivity in biomedical and biological research.

An adaptive plasmonic lens

” Nature highlights a recent ACS Photonics study on a novel reconfigurable lens”  In constant search for miniaturizing commercial optical devices, integrated micro-optical elements play a central role in the development of applications that aim to improve high-density data storage and imaging. Until now, such devices presented the drawback of fine aligning and adjusting the […]

Plasmonic lasers: On the fast track

The dependence of the output power on the delay indicated that the generated pulse length was less than a picosecond, which suggested an extremely high direct-modulation rate. Moreover, finer interferometric measurements of the spectral composition of the radiation allowed the authors to establish that the generated pulse was even shorter; on a subpicosecond scale. Thus, […]

Nanosphere lithography for device fabrication

Nanosphere lithography (NSL), originally termed ‘ natural lithography’ by its inventors,1 is becoming a widespread bottom-up technique to pattern solid surfaces at the sub-micrometer and nanoscales. Groups such as Van Duyne’s2 at Northwestern University and others3 undertook pioneering work on NSL in the 1990s and early this decade, and a growing number of research laboratories around the globe […]

UT Austin Engineers Build First Nonreciprocal Acoustic Cir...

AUSTIN, Texas — A team of researchers at The University of Texas at Austin’s Cockrell School of Engineering has built the first-ever circulator for sound. The team’s experiments successfully prove that the fundamental symmetry with which acoustic waves travel through air between two points in space (“if you can hear, you can also be heard”) can be broken […]
