โœฆ Synopsis

In this work, we review the implementation of nano-structured materials in surface plasmon resonance (SPR) sensors for the detection of adsorbed molecules. More specifically, we study nano-porous alumina films supported by gold (Au) or aluminum (Al) thin films in SPR sensors under the Kretchmann configuration. The enhanced response of such a sensor is calculated by theoretical simulation and is compared to the most widely used "classic" Au SPR sensor. It is concluded that both Al/nano-porous alumina and Au/nano-porous alumina setup provide better response than the "classic" Au SPR sensor with Au/nano-porous alumina setup providing the best response.

An optical fiber sensor based on the surface plasmon resonance (SPR) is proposed as a way to monitor the concentration of plasma deposited hydrophilic functional groups on material surfaces by the SPR dip shift in wavelength. The SPR optical fiber sensor was installed in the isopropanol (IPA) treatm
