A strong interaction between cyanide anion and copper(I) cation in combination with non-resonant Raman fingerprinting allows the selective sensing of aqueous free cynanide with high sensitivity to parts per billion (ppb)-level.

This study involves two aspects of our investigations of plasmonics-active systems: (i) theoretical and simulation studies and (ii) experimental fabrication of plasmonics-active nanostructures. Two types of nanostructures ...
