In this paper, we report an all-dielectric metamaterial terahertz biosensor, which exhibits a high Q factor of 35 at an 0.82 resonance peak. A structure with an electromagnetically induced transparency effect was designed and fabricated to perform a Mie resonance for the terahertz response. The biosensor exhibits a limit of detection of 100 pg/mL for cytokine interleukin 2 (IL-2) and a linear response for the logarithm of the concentration of IL-2 in the range of 100 pg/mL to 1 μg/mL. This study implicates an important potential for the detection of cytokines in serum and has potential application in the clinical detection of cytokine release syndrome.
在本文中,我们报道了一种全介质超材料太赫兹生物传感器,它在0.82共振峰处展现出35的高品质因数。设计并制作了一种具有电磁诱导透明效应的结构,以实现太赫兹响应的米氏共振。该生物传感器对细胞因子白细胞介素2(IL-2)的检测限为100 pg/mL,并且在100 pg/mL至1 μg/mL范围内对IL-2浓度的对数呈线性响应。本研究表明该传感器在血清中细胞因子检测方面具有重要潜力,并且在细胞因子释放综合征的临床检测中具有潜在应用价值。
