The chiroptical properties of pure inorganic material are reported by Shunai Che and co-workers on page 3784. The properties are investigated by dispersing achiral metal nanoparticles into chiral mesoporous silica, due to collectively asymmetric plasmon interactions of metal nanoparticles arranged along a helical pore orientation. Such chiral materials will have novel applications for biosensing, chiral recognition, and detection, based on the importance of surface plasmon resonance (SPR) in biological structures.
