Integrated laser ablation and computed tomography: detecting the chemical footprint of microplastics and reconstructing 3D biological tissues
AI summary Read the abstract
Researchers combined micro-computed tomography with laser ablation ICP-MS to detect PET microplastics in rat tissue by mapping antimony and cobalt metal markers, enabling three-dimensional volumetric reconstruction of microplastic locations in situ — a dual-modality approach that overcomes the inability of CT imaging alone to definitively identify plastic particles.

A study of the characterization potential of microplastics embedded in soil applying 3D X-ray microtomography
AI summary Read the abstract
Scientists used 3D X-ray microtomography to detect and characterize microplastics in soil samples, successfully identifying 80-95% of particles as small as 0.05 mm and classifying them by shape, volume, and depth. This non-destructive imaging technique could transform how we monitor microplastic contamination in agricultural soils and track how particles move through the ground over time.
Integrated laser ablation and computed tomography
AI summary Read the abstract
Scientists developed a new way to find and map tiny plastic particles (microplastics) hiding inside body tissue by combining two techniques: a 3D imaging scan (like a CT scan) and a chemical detection method that spots trace metals found in common plastics like PET (the material in water bottles). This matters because current methods struggle to reliably detect microplastics in our organs, and this proof-of-concept approach—tested in rat tissue—could eventually help researchers better understand how much plastic accumulates in our bodies and where it ends up, an important step toward figuring out what that means for our health.
