In the last two decades, plasmon resonance in gold nanoparticles (Au NPs) has been the
subject of intense research efforts. Plasmon physics is intriguing and its precise modelling …

Gold is a precious metal with a characteristic bright and beautiful hue known as the golden
yellow color.(1) As of 2012, a total of 174,100 tons of Au has been mined in human history …

Gold nanoparticles have been used in biomedical applications since their first colloidal
syntheses more than three centuries ago. However, over the past two decades, their …

Coinage metals, such as Au, Ag, and Cu, have been important materials throughout
history.(1) Although in ancient cultures they were admired primarily for their ability to reflect …

Surface-enhanced Raman scattering (SERS)-based signal amplification and detection
methods using plasmonic nanostructures have been widely investigated for imaging and …

By using femtosecond transient absorption spectroscopy with visible pump and IR probe to
observe generation of injected electrons, we could directly observe plasmon-induced …

Using time-dependent density functional theory, we present a fully quantum mechanical
investigation of the plasmon resonances in a nanoparticle dimer as a function of interparticle …

Noble metal nanoparticles are promising catalysts in electrochemical reactions, while
understanding the relationship between the structure and reactivity of the particles is …

We review the syntheses, optical properties, and biological applications of cadmium
selenide (CdSe) and cadmium selenide–zinc sulfide (CdSe–ZnS) quantum dots (QDs) and …

In this study, we report on ultrasensitive protein detection with lithographically prepared
plasmonic nanostructures. We have engineered optical nanosensors by the combined …
