The discovery of the enhancement of Raman scattering by molecules adsorbed on
nanostructured metal surfaces is a landmark in the history of spectroscopic and analytical …

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 …

When metal nanoparticles are arranged in an ordered array, they may scatter light to
produce diffracted waves. If one of the diffracted waves then propagates in the plane of the …

Metal nanoparticles are being extensively used in biomedical fields due to their small size-to-
volume ratio and extensive thermal stability. Gold nanoparticles (AuNPs) are an obvious …

Cancer has been one of the major threats to the lives of human beings for centuries.(1)
Current cancer therapies mainly include surgery, chemotherapies, and radiotherapies …

Colloidal self-assembly refers to a solution-processed assembly of nanometer-/micrometer-
sized, well-dispersed particles into secondary structures, whose collective properties are …

Localized surface plasmon resonance (LSPR) is a longstudied nanoscale phenomenon of
considerable recent interest. 1, 2 These resonances, associated with noble metal …

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 …

Nanoparticles are generally defined as any particulate material for which at least one
dimension lies in the range of 1− 100 nm. 1− 3 They can exist in various shapes, such as …

Gold is a multifunctional material that has been utilized in medicinal applications for
centuries because it has been recognized for its bacteriostatic, anticorrosive, and …
