Doped nematic phases: a tool for amplifying and detecting chirality.
Doping nematic liquid crystals with non-racemic chiral compounds induces twisted nematics (cholesteric phases). This phenomenon allows the detection via spectroscopic or non-spectroscopic methods of chiral compounds through the detection (and eventually quantification) of the macroscopic induced cholesteric twist.
