Identification of microplastic fibres released from COVID-19 test swabs with Raman imaging
AI summary Read the abstract
Researchers used Raman imaging to identify microplastic fibers released from COVID-19 nasal test swabs, confirming that these widely used medical devices shed plastic particles. While the abstract provides limited detail, the study adds to growing evidence that disposable medical products are a source of microplastic contamination, particularly concerning given that test swabs are inserted directly into the body.

Raman imaging to identify microplastics released from toothbrushes: algorithms and particle analysis
AI summary Read the abstract
Researchers used Raman imaging to identify and analyze microplastic particles released from toothbrushes during simulated brushing. They found that toothbrushes shed detectable plastic fragments, including nylon and other polymer types, confirming that oral hygiene products can be a direct source of microplastic exposure. The study developed improved algorithms for identifying these particles, which could help standardize microplastic detection in consumer product testing.

Raman Spectroscopy Based Approaches for Microplastics Investigations
AI summary Read the abstract
Researchers reviewed Raman spectroscopy-based approaches — including confocal Raman microscopy, surface-enhanced Raman scattering, and automated imaging — for identifying and characterizing microplastics in environmental samples, highlighting their superior chemical specificity compared to FTIR for sub-10-μm particles. Accurate chemical identification of microplastics at the nanoscale is foundational for both environmental monitoring and toxicological research, as particle composition (polymer type and additives) strongly influences biological harm.
