我们提出了一种基于二硫化钼的太赫兹表面等离子体生物传感器，用于检测血液成分。MoS 2厚度的变化对谐振峰漂移量有很大影响。该传感器的超高波长灵敏度和分辨率分别为715.59 μ m/RIU和1.40 × 10 ~（-7）RIU。当传感器整体结构变化± 0.4%时，谐振频率的最大相对误差为1.3699%，峰值损耗的最大相对误差为1.5327%，均在合理范围内，不会影响传感器的性能。
We propose a terahertz surface plasmon biosensor based on MoS2 for detecting blood components. The change of the thickness of MoS2 has a great influence on the amount of resonance peak drift. The ultra-high wavelength sensitivity and resolution ratio of the biosensor are 715.59 mu m/RIU and 1.40 x 10-7 RIU, respectively. When the overall structure of the sensor changes by +/- 0.4%, the maximum relative error of the resonance frequency is 1.3699%, and the maximum relative error of the peak loss is 1.5327%, which are all within a reasonable range and will not affect the sensor' performance.
