From Pasteur to Plasmons: How Plasmonics Entered the Age of Optical Asymmetry

Taking a historical snapshot of chiral plasmonics, after discovery in the 19th century and becoming more important in the 20th century for pharmacological and biological applications, in the early 2000s, twisted plasmonic nanostructures revealed strong chiroptical responses. However, their fabrication remained complex and limited. The 2010s introduced enabling tools such as DNA origami, colloidal self-assembly, and metamaterials, allowing precise control over chiral plasmonic architectures—but..
