Is LA-ICP-MS the next frontier in monitoring and imaging microplastics in biological tissues?
AI summary Read the abstract
This paper evaluated whether laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS) could become a leading technique for detecting and imaging microplastics within biological tissues. If validated, this approach could allow researchers to precisely map where plastic particles accumulate in organs, greatly improving understanding of how microplastics affect living organisms including humans.

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.
In situ imaging of microplastics in living organisms based on mass spectrometry technology
AI summary Read the abstract
Researchers reviewed mass spectrometry-based imaging techniques for detecting microplastics inside living organisms, comparing different ion source methods for their ability to visualize plastic particles in biological tissue. They found that these techniques can provide both spatial distribution maps and chemical composition analysis of microplastics at high resolution. The study suggests that mass spectrometry imaging could become a powerful tool for understanding how microplastics accumulate and distribute within living systems.
Raman microspectroscopy and laser-induced breakdown spectroscopy for the analysis of polyethylene microplastics in human soft tissues
AI summary Read the abstract
Researchers developed a combined technique using Raman microspectroscopy and laser-based analysis to detect polyethylene microplastics in human soft tissue samples. The method can identify both the plastic polymer and any associated inorganic elements in tissue. This kind of detection tool is important for understanding whether microplastics accumulate in specific human organs and what health effects they might have.
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.
