Enantiodiscrimination: Moiré Chiral Metamaterials (Advanced Optical Materials 16/2017)

Zilong Wu and Yuebing Zheng developed a new type of plasmonic metamaterials (known as moiré chiral metamaterials) with tunable chiroptical properties in article number 1700034. The moiré chiral metamaterials are fabricated by stacking two layers of identical achiral Au nanohole arrays into moiré patterns. Label-free enantiodiscrimination of chiral molecules at the pictogram level is achieved using the moiré chiral metamaterials.
