How FLIM Microscopy helps to detect microplastic pollution

Dec 28, 2020
The use of autofluorescence in biological samples is a widely used method to gain detailed knowledge about systems or organisms. This property is not only found in biological systems, but also anthropogenic materials, such as plastics, can emit autofluorescence. Measuring the temporal resolution of this emitted autofluorescence with fluorescence lifetime imaging microscopy (FLIM) generates data on fluorescence decay, i.e. the fluorescence lifetime (τ). Our study showed that the fluorescence lifetime can be used for a label-free characterization of plastics (microplastics). Read article
