International research project leads to a breakthrough in terahertz spectroscopy

Although terahertz spectroscopy has great potential, especially for environmental monitoring and security screening applications, it previously could not be used effectively to study nanocrystals or molecules at extremely low concentrations. An international team led by Professor Luca Razzari at the INRS Énergie Matériaux Télécommunications Research Centre has found a solution to this problem by increasing the technique's sensitivity using metallic nanostructures, as explained in an article published in Nano Letters in January 2015.
