Summary

Researchers found that heating plastic particles increases their natural fluorescence, making microplastics much easier to detect under a microscope without chemically altering them. This simple heat treatment offers a cost-effective method to improve microplastic detection in environmental and biological samples.

Considering the outcomes of this study, heat treatment is a useful tool to make microplastic particles more visible in microscopic applications without readable destruction of their composition. The heat treatment of plastics for defined incubation times and temperatures can lead to a distinct increase in autofluorescence intensity of the plastics and therefore serve as an easy and cost-effective applicable method for microplastic detection.
