Catcher in the tap: The optical response to metal ions of new coumarin-based fluorescent chemosensors was studied in different media from solution, to cells in vitro, in the presence of silica core/polyethylene glycol (PEG) shell nanoparticles or in polyvinyl chloride (PVC)-based polymeric membranes. The doped membranes were used to develop an optical sensing array for Hg2+ ions probing in real matrices based on the computer screen photo-assisted technique (CSPT) (see figure).
