An aluminum-based deep-ultraviolet surface plasmon resonance (DUV-SPR) sensor is promising for biological applications. Design aspects of a DUV-SPR sensor are here considered by using Fresnel multilayer model. Angular and wavelength interrogation modes are used, where fused silica, sapphire, and acrylic solacryl ultraviolet transmittance (acrylic SUVT) are used as optical substrates. Aluminum at its oxidized state (alumina) is also considered as an aluminum overlayer. Our 4-layer Kretschmann-Raether-based SPR sensor is applied for gaseous and aqueous solutions, where some figures of merit are used to analyze the sensor performance. Values for sensitivity, linewidth (FWHM, full width at half maximum), and FOM (figure of merit or quality factor) are calculated. Resolution is also found and compared with other devices by using a known formulation. The results indicate that our sensor has a higher sensitivity for both gaseous and aqueous solutions when compared with the visible light-based sensor. For aqueous solutions, analyte is simulated as a bulk or a monolayer. Therefore, DUV-SPR sensors are a good alternative to the conventional visible-based SPR devices, where the performance is similar or higher for some conditions, having a higher affinity for some proteins.

铝基深紫外表面等离子体激元共振（DUV-SPR）传感器有望用于生物学应用。在这里，通过使用菲涅耳多层模型来考虑DUV-SPR传感器的设计方面。使用角度和波长询问模式，其中熔融石英，蓝宝石和丙烯酸溶胶丙烯酸紫外线透射率（丙烯酸SUVT）用作光学基材。氧化态的铝（氧化铝）也被认为是铝覆盖层。我们基于Kretschmann-Raether的4层SPR传感器适用于气态和水溶液，其中一些品质因数用于分析传感器性能。计算出灵敏度，线宽（FWHM，半高全宽）和FOM（品质因数或品质因数）的值。还可以找到分辨率，并通过使用已知公式将其与其他设备进行比较。结果表明，与基于可见光的传感器相比，我们的传感器对气态和水溶液都具有更高的灵敏度。对于水溶液，分析物被模拟为整体或单层。因此，DUV-SPR传感器是传统基于可见光的SPR设备的良好替代品，后者在某些条件下的性能相似或更高，对某些蛋白质具有更高的亲和力。
