Metamolecules that switch handedness at light-speed: Optically switchable chiral terahertz metamolecules developed

Scientists have created the first artificial molecules whose chirality can be rapidly switched from a right-handed to a left-handed orientation with a beam of light. This holds potentially huge possibilities for the application of terahertz technologies across a wide range of fields, including biomedical research, homeland security and ultrahigh-speed communications.
