I am considering to use so called sticky slides (http://ibidi.com/xtproducts/en/ibidi-Labware/sticky-Slides/sticky-Slide-8-Well) and mount them on CaF2 microscope slides. In the product spec it says that "The sticky bottom itself is a 50 µm biocompatible double–faced adhesive tape". 

Does anyone know whether this tape gives rise to any interference in Raman? Can the components of the tape wash out into the chambers? I am working with confocal SERS, so the less foreign substances in my samples the better.
