本文研究了一种带有微孔芯片的表面等离子体共振(SPR)传感器,旨在提高灵敏度并降低噪声。我们提出的理论模拟和实验结果所获得的建议结构。与大多数使用平面金膜的SPR传感器相比,该阱结构使灵敏度提高了128%。通过将表面等离子体波(SPW)限制在阱内,我们能够将噪声降低两倍以上。提高的灵敏度和较低的噪声使我们提出的新型微孔芯片适用于小分子或痕量检测。
In this paper, we study a surface plasmon resonance (SPR) sensor with a microwell chip that is aimed at improving the sensitivity and reducing the noise. We present both theoretical simulations and experimental results obtained for the proposed structure. In comparison to most SPR sensors that use planar gold films, this proposed well structure enables a sensitivity enhancement of 128%. By confining the surface plasmon wave (SPW) within the well, we are able to reduce the noise by more than twice. The increased sensitivity and lower noise makes our proposed novel microwell chip suitable for small molecule or trace amount detection.
