Surface plasmon resonance (SPR) sensing utilizing far- and deep-ultraviolet light.
This study explores the development and applications of surface plasmon resonance (SPR) sensors operating in the far-ultraviolet (FUV) and deep-ultraviolet (DUV) regions. Aluminum (Al) is utilized as the plasmonic material. The experimental setup leverages an attenuated total reflectance (ATR) spectrometer with Al thin films deposited on prisms, enabling measurements under atmospheric conditions. These results highlight the potential for tuning SPR wavelengths through material and configuration adjustments. Enhanced performance compared to visible-region SPR sensors is demonstrated, with promising selectivity and detection capabilities. Furthermore, a flow measurement system designed for real-time monitoring underscores the practical utility of UV-SPR sensors. By fixing the measurement wavelength, rapid changes in environmental conditions can be observed with a time resolution of 0.1 s. This study establishes the foundation for advanced UV plasmonic sensors with broad implications for medical diagnostics, environmental monitoring, and biochemical analysis.
