Abstract

Embodiments of the invention provide a spin biosensor and a terahertz time domain spectroscopy system. The spin biosensor comprises a substrate, a metamaterial array layer and a ferromagnetic structure layer, wherein the metamaterial array layer and the ferromagnetic structure layer are located on both sides of the substrate, or the metamaterial array layer and the ferromagnetic structure layer are located on the same side of the substrate, a passivation layer is further disposed between the metamaterial array layer and the ferromagnetic structure layer, and the metamaterial array layer is located at the outermost layer. The use of ferromagnetic materials as the generating device greatly reduces the cost while ensuring the transmission power. The metamaterial is directly fabricated on thesurface of the device, and the detector member is closely attached to the emitting source, thereby eliminating the complicated optical path design and realizing the integration of the terahertz biosensor.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of biosensing, in particular to a spin biosensor and a terahertz time-domain spectroscopy system. Background technique [0002] Terahertz (THz) wave refers to the frequency range of 0.1-10THz, the corresponding wavelength is 3mm-30μm, and the frequency band is between millimeter wave and infrared optics. The development of terahertz time-domain spectroscopy technology based on ultrafast laser has promoted the rapid development of terahertz technology. The photon energy of terahertz radiation is very low, so it can realize the non-destructive detection of the measured substance; at the same time, the vibration of many biological macromolecules Both the energy level and the rotational energy level are in the terahertz band, therefore, the detection and fingerprinting of matter can be carried out through the characteristic resonance. [0003] Spintronics originated in 1988. Professor Fell...
