The symmetry of metal ions in inorganic nanofilms can be manipulated by the transfer of optical spin from a chiral light beam. Here the authors present a route to functional manipulation that does not require the application of extreme conditions.

Chiral near fields possessing enhanced asymmetry (superchirality), created by the interaction of light with (chiral) nanostructures, potentially provide a route to novel sensing and metrology technologies for biophysical applications. However, the me

It is generally believed that rapid dissipation means that spatially precise heating is not feasible via thermoplasmonic means. Here, the authors induce highly localized heating around plasmonic nanostructures by pulsed laser irradiation, which effec

Nanophotonic platforms in theory uniquely enablefemtomoles of chiral biological and pharmaceutical molecules to be detected, through the highly localized changes in the chiral asymmetries of the near fields that they induce. However, current chiral n

Chiral nanophotonic platforms provide a means of creating near fields with both enhanced asymmetric properties and intensities. They can be exploited for optical measurements that allow enantiomeric discrimination at detection levels greater than 6 o

Light scattering from chiral plasmonic structures can create near fields with an asymmetry greater than the equivalent circularly polarised light, a property sometimes referred to as superchirality. These near fields with enhanced chiral asymmetries
