ClearSterile inflammation induced by respirable micro and nano polystyrene particles in the pathogenesis of pulmonary diseases
Researchers exposed human lung and immune cells to polystyrene micro and nanoparticles and found they triggered a type of inflammation that does not require infection, called sterile inflammation. Aged (oxidized) particles and those that interacted with immune cells were especially potent at activating inflammatory pathways including the NLRP3 inflammasome. This suggests that breathing in airborne microplastics could cause chronic lung inflammation over time.
Raman Tweezers for Small Microplastics and Nanoplastics Identification in Seawater
Researchers used Raman tweezers - optical tweezers combined with Raman spectroscopy - to capture and chemically identify individual small microplastic and nanoplastic particles in seawater samples in situ. This novel technique could enable real-time identification of the smallest plastic particles in marine environments, filling a critical gap in nano- and micro-plastic detection.
