Coherent THz Spectrometry in Chemistry and Biology

Terahertz radiation is defined by the frequency range of 0.1 to 10 THz (1 THz equals 1 trillion cycles per second) and interest in its application to the medical, pharmaceutical and biological sciences has grown in the last decade.

A broad theme of THz research has been to apply the coherent nature of the radiation from our various sources and receivers to biological and chemical systems. Coherent transmission and detection provides a referenceable probe for building a metrology to characterise the manifold and complex distinct, collective vibrational (i.e. ‘normal’) modes present in many (bio)materials. The study of the rich vibrational density of states at THz frequencies at the mesoscopic scale will increasingly inform the basis of nano-engineering for novel macroscopic materials’ behaviour. Our recent papers report the unconventional utility of the Vector Network Analyser (VNA) in this effort. One shows the VNA sensitive to the same chemical reaction processes in a hardening bio-cement as seen by neutron scattering. The challenge in all experimental cases is how to ‘hold’ the sample. Our metrology innovates schemes for supporting gantry suited to achieving a workable S/N while remaining benign to the system under study.
