We propose a terahertz surface plasmon biosensor based on ${\mathrm{MoS}}_2$ for detecting blood components. The change of the thickness of ${\mathrm{MoS}}_2$ 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 $\mathrm{\mu }$m/RIU and 1.40 $\times$ 10⁻⁷ RIU, respectively. When the overall structure of the sensor changes by $\pm$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.

太赫兹波段基于MoS2的D形表面等离子体共振生物传感器

我们提出了一种基于太赫兹表面等离子体生物传感器 ${\mathrm{硫化钼}}_2$用于检测血液成分。厚度的变化${\mathrm{硫化钼}}_2$对共振峰漂移量有很大影响。生物传感器的超高波长灵敏度和分辨率为715.59 $\mathrm{\mu }$m/RIU 和 1.40 $\times$分别为 10 ^-7 RIU。当传感器的整体结构发生变化时$\pm$0.4%，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。
