Abstract

The invention discloses a terahertz spectral analysis device and a terahertz spectral analysis method for a biofilm, and relates to a device for performing terahertz wave band spectral analysis on the biofilm and a method for performing terahertz wave band spectral detection on the biofilm by using terahertz surface plasma waves. The terahertz spectral analysis device for the biofilm comprises a semiconductor chip (3), two blades (2) placed in parallel, a terahertz wave source (11) and a terahertz time domain spectrograph (6); the two blades are vertical to the semiconductor chip (3); the distances between knife edges of the two blades (2) and the upper surface of the semiconductor chip (3) is smaller than an attenuation distance of the terahertz surface plasma wave (4) with the largest frequency in the air; and the distance between the two blades is smaller than the transmission distance of the terahertz surface plasma wave with the largest frequency on the surface of a semiconductor. The sensitivity and the signal to noise ratio of the spectral analysis device are improved by using strong electric-field strength of the terahertz surface plasma wave in a small space on the surface of the semiconductor.

Description

technical field [0001] The invention relates to a device for performing terahertz band spectrum analysis on biological films, and a method for performing terahertz band spectrum detection on biological films by using terahertz surface plasma waves. Background technique [0002] Terahertz waves generally refer to electromagnetic waves with a frequency range between 0.1THz and 10THz, and its wave band is between far infrared and microwave. For a long time, spectroscopic studies of biomolecules have been carried out in the frequency range above 10 THz, and detailed information on molecular structures and properties are usually obtained from Raman and near-infrared spectroscopy. In recent years, the development of terahertz wave sources has made a breakthrough in terahertz spectroscopy technology, and the application research of terahertz waves has attracted more and more attention. [1] . The transitions between vibrational energy levels and rotational energy levels of many po...
