AB  - Microplastics (MP) are micrometric plastic particles present in drinking water, 
      food and the environment that constitute an emerging pollutant and pose a menace 
      to human health. Novel methods for the fast detection of these new contaminants 
      are needed. Fluorescence-based detection exploits the use of specific probes to 
      label the MP particles. This method can be environmentally friendly, low-cost, 
      easily scalable but also very sensitive and specific. Here, we present the 
      synthesis and application of a new probe based on perylene-diimide (PDI), which 
      can be prepared in a few minutes by a one-pot reaction using a conventional 
      microwave oven and can be used for the direct detection of MP in water without 
      any further treatment of the sample. The green fluorescence is strongly quenched 
      in water at neutral pH because of the formation dimers. The ability of the probe 
      to label MP was tested for polyvinyl chloride (PVC), polyethylene (PE), 
      polyethylene terephthalate (PET), polypropylene (PP), polystyrene (PS), poly 
      methyl methacrylate (PMMA) and polytetrafluoroethylene (PTFE). The probe showed 
      considerable selectivity to PVC MP, which presented an intense red emission after 
      staining. Interestingly, the fluorescence of the MP after labeling could be 
      detected, under excitation with a blue diode, with a conventional CMOS color 
      camera. Good selectivity was achieved analyzing the red to green fluorescence 
      intensity ratio. UV-Vis absorption, steady-state and time-resolved fluorescence 
      spectroscopy, fluorescence anisotropy, fluorescence wide-field and confocal laser 
      scanning microscopy allowed elucidating the mechanism of the staining in detail.
