In this seminal, we proposed a silicon and two-dimensional MXene (Ti₃C₂T_x) layer-based surface plasmon resonance (SPR) biosensor. Use of MXene layer facilitates the adsorption of biomolecules due to its larger surface area, stronger light matter interaction and higher binding energies. Silver, silicon thicknesses and the number of MXene layers of proposed SPR have been optimized for the best performance. Sensitivity, detection accuracy, and figure of merit acquired with 50 nm silver, 5 nm silicon film and for monolayer MXene at 633 nm wavelength is 231^οRIU⁻¹ 0.17 Degree⁻¹ and 39.83 RIU⁻¹. Silicon layer is used between silver and MXene to increase the sensitivity. Proposed SPR sensor with silicon shows sensitivity enhancement of 99.83% and 95.68% over conventional SPR and proposed SPR without silicon respectively. However, highest sensitivity is reached to 349.9^οRIU⁻¹ for 50 nm silver and 7 nm silicon without any MXene layer.

在此开创性研究中，我们提出了一种基于硅和二维MXene（Ti ₃ C ₂ T _x）层的表面等离振子共振（SPR）生物传感器。由于其较大的表面积，更强的光物质相互作用和更高的结合能，MXene层的使用促进了生物分子的吸附。建议的SPR的银，硅厚度和MXene层数已得到优化，以实现最佳性能。灵敏度，检测精度，并且在633nm波长具有50纳米银，5纳米的硅膜和单层MXene获取品质因数是231 ^ο RIU ^-1 0.17度^-1和39.83 RIU ^-1。在银和MXene之间使用硅层以提高灵敏度。提议的带有硅的SPR传感器的灵敏度分别比传统的SPR和提议的不带硅的SPR分别提高了99.83％和95.68％。然而，最高灵敏度达到349.9 ^ο RIU ^-1为50纳米银和7nm的硅而没有任何MXene层。
