Abstract :
In this work we present a multichannel chemical sensor based on Surface Plasmon Resonance (SPR) in a Plastic Optical Fiber (POF), for the detection of metal ions. The SPR sensing platform was realized removing the cladding of a plastic optical fiber along half circumference, spin coating on the exposed core a buffer of Microposit S1813 photoresist, and finally sputtering a thin gold film by using a sputtering machine. The planar gold layer can be employed for the preparation of a Self Assembled Monolayer (SAM) with specific binding receptor. In the present study two different ligands for Fe(III) and Cu(II) are linked on the gold surface obtaining two SAM-POF sensors.
