Nano metamaterials for ultrasensitive Terahertz biosensing [PDF]

Scientific Reports, 2017
AbstractAs a candidate for a rapid detection of biomaterials, terahertz (THz) spectroscopy system can be considered with some advantage in non-destructive, label-free, and non-contact manner. Because protein-ligand binding energy is in the THz range, especially, most important conformational information in molecular interactions can be captured by THz ...
