Summary

Researchers demonstrated that multimodal multiphoton tomography, combining autofluorescence, lifetime imaging, and other optical techniques, can effectively identify and characterize microplastic particles. The study suggests this advanced imaging approach could help standardize microplastic detection methods, addressing a key challenge in environmental monitoring.

Body Systems
Study Type In vivo

Microplastic studies are crucial due to their impact on human health and the environment. However, the lack of a standardized method for microplastic identification and quantification hinders comprehensive analysis. Our research addresses these challenges by employing the advanced imaging technique Multimodal Multiphoton Tomography (MPT) including two-photon autofluorescence (AF), fluorescence lifetime imaging (FLIM) with phasor analysis, second harmonics generation (SHG), and reflectance confocal microscopy (RCM) with 50/80 MHz femtosecond laser pulses. The combined imaging approach allows also tracking of cosmetics with microplastics in-vivo in the human skin.
