Researchers have demonstrated a way to make large-scale chiral films from achiral semiconductors. The feat could pave the way for new antireflective coatings and noninvasive blood-sugar monitors.

Nonchiral Clusters Self-Assemble into Chiral Films
Researchers have demonstrated a method to create circular polarizing films from nonchiral nanoclusters that form spiral chains during drying.
