The present invention relates to a method for the detection of at least one nano or micro plastic particle comprised in a heterogeneous matrix material comprising the following steps: applying of at least one part of a heterogeneous matrix material comprising at least one nano or micro plastic particle onto at least a portion of a surface of a conductive support thereby forming a first layer onto said surface, irradiating of at least a portion of said first layer with at least one ion beam, thereby forming an irradiated layer, detecting of the at least one nano or micro plastic particle comprised in said irradiated layer by a detection method chosen from the group of Raman nanoscopic techniques, or infrared nanoscopic techniques, or charge dependent detection methods or combination thereof. The present invention allowed good detection of micro and nano plastic particles with high resolution and sensitivity.
