Abstract
A new surface plasmon resonance (SPR) sensing probe is presented. The probe is based on retro-reflection, consisting of a stable, one-piece substrate that is simple to construct. The orientation of the sensing surface requires a minimal sample volume, and the device is easily opt imized for maximum sensitivity in different applications. The sensor p resented here exhibited a sensitivity of 3.36 x 10(-5) refractive inde x units. The versatility and simplicity of this new sensor configurati on provide the potential to introduce SPR sensing techniques to indust rial applications. (C) 1997 Elsevier Science S.A.
