Abstract
The development of an in-situ sensor for the monitoring of concentration of metallic ions in oceans and freshwaters is needed for environmental and industrial studies. To detect multiple ions, in real time, without any tag, we have developed a multi spectral Surface plasmon resonance-based sensor. Capture of ions is achieved using an ion-imprinted polymer functionalized gold surface. The gold film is sequentially illuminated by a finite number of wavelengths and the spectral position of the plasmonic resonance is extracted from this set of images, over the whole sensor surface.
