Plasmonic structures exhibit a wide range of physical characteristics, which are benefited by the localized and intensified light–matter interaction. There have been many recent advancements with ...

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), ...

As a result, a large variety of biosensors, which incorporate biological probes coupled to a transducer, have been developed during the last two decades for environmental, industrial, and biomedical ...

Plasmonic resonances have opened new opportunities to manipulate nanoscale light–matter interactions, allowing to overcome the inherent limitations of natural materials. This field was pioneered by ...

Excessive CO 2 emission triggers many hazards such as global warming, glacier melting, and sea level rise, which seriously threaten the ecological balance and human survival. Converting CO 2 into high ...

Plasmonics is the study of the interaction between electromagnetic waves and free electrons in a metal. When light strikes a metal nanostructure, it can excite collective oscillations of the free ...

A recent study in the National Science Review detailed the dynamic and reversible optical modulation of surface plasmons. This modulation is achieved through the transport of hot carriers. This study ...

COVID-19 testing leans heavily on reverse transcription polymerase chain reaction (RT-PCR) technology. Although RT-PCR is currently the most sensitive method for detecting viral RNA—such as the viral ...

Scientists are harnessing light-sensitive nanoparticle sensors to detect chemicals in real time, no lab prep needed. They have potential in medicine, pollution tracking, and in industry. Image Credit: ...

Do you know more than 50 percent of microplastic pollution in our oceans comes from color paints? Almost every object that people throw into the ocean, whether it be a broken toy, a small bottle cap, ...
