Magnetically-responsive nanophotonics with iron-doped silver nanoparticles

Nanostructures play an important role in photonics, thanks to the wide range of active and passive optical effects they can generate. For instance, silver (Ag) nanoparticles (NPs) are renowned for their plasmonic properties exploitable for quenching or

Brownian motion of gold nanostructures made visible using SERS fluctuations due to single molecules

Surface-Enhanced Raman Spectroscopy (SERS) a surface-sensitive effect which produces a dramatic enhancement of the Raman signature of molecules adsorbed on some nanostructures such as gold nanoparticles. In practical terms, SERS allows the fast acquisition of spectral datasets

Detecting nerve gases VX and Tabun with a handheld device

Threats from nerve gases, or more accurately termed chemical warfare agents, constitute a serious security issue of increasing global concern because of surging terrorist activities. A big problem with nerve gases are that they are very challenging
