Query: Reconfigurable Plasmonic Chirality: Fundamentals and Applications   Molecular chirality is a geometric property that is of great importance in
chemistry, biology, and medicine. Recently, plasmonic nanostructures that
exhibit distinct chiroptical responses have attracted tremendous interest,
given their ability to emulate the properties of chiral molecules with tailored
and pronounced optical characteristics. However, the optical chirality of such
human-made structures is in general static and cannot be manipulated
postfabrication. Herein, different concepts to reconfigure the chiroptical
responses of plasmonic nano- and micro-objects are outlined. Depending on the
utilized strategies and stimuli, the chiroptical signature, the 3D structural
conformation, or both can be reconfigured. Optical devices based on plasmonic
nanostructures with reconfigurable chirality possess great potential in
practical applications, ranging from polarization conversion elements to
enantioselective analysis, chiral sensing, and catalysis.
