Terahertz Spectroscopy
Vibrational resonance spectroscopy in the Terahertz (THz) range (0.1-3 THz or 3-100 cm-1) is a fast emerging technique for fingerprinting biological molecules and other bio-materials. THz radiation interacts with the low-frequency internal molecular vibrations involving the weakest hydrogen bonds and other weak interactions by exciting these vibrations. The THz absorption spectra of bio-molecules reveal the resonance features that reflect these low frequency molecular motions. Well resolved THz spectra from biological molecules and organisms are specific to the sequencing and the three-dimensional structure and can be used for their fast characterization and fingerprinting. The spectral range below 1 THz is especially attractive for practical applications because of low disturbance from liquid water (2.5 order less absorption compare to far IR) or other solvents, and from water vapor absorption (sensors do not require evacuation or purging with dry nitrogen). A big advantage of THz spectroscopy is that it is an optical method and is nondestructive for living specimens.
Terahertz Biosensors
THz spectroscopic sensors with imaging capability are automated, simple, optical, apertureless, transmission frequency domain THz spectroscopic microscope instruments, operating at room temperature with high sensitivity, high spectral resolution, spatial resolution below the diffraction limit, and integrated with a microfluidic channel chip for sample materials.

About Us
Vibratess, LLC (Vibrational Terahertz Spectroscopic Sensors)    was formed in 2007 as a spin-off from the University of Virginia to develop and commercialize low terahertz (THz) resonance spectroscopy for biological materials detection and characterization. Vibratess is a woman-owned small business that has received continuous funding from Small Business Innovation Research Contracts.
Itís hard to believe in this age of cellular, Wi-Fi, and Bluetooth connections that any part of the electromagnetic spectrum has not been called into service to fill our hunger for more powerful and pervasive technology. But there they stand, unused and for the most part ignored, the terahertz frequencies. Lying between 100 gigahertz and 10 terahertz, they rest on the cusp between electronics and photonics with a reputation for being difficult to work with.
