Ultrasensitive Plasmonic Chiral SERS Substrate for Ligand-Free Enantioselective Discrimination and Molecular Fingerprinting
{{output}}
In this work, we have fabricated plasmonic chiral silver nanohelices with a strong chiroptic response using the glancing angle deposition (GLAD) technique. These nanostructures have been explored for label-free enantioselective surface-enhanced Raman spectrosc... ...
