Micro- and nanoplastic particles, including common forms like polyethylene polystyrene, have been identified as relevant pollutants, potentially causing health problems in living organisms. The mechanisms at the cellular level largely remain to be elucidated. This study aims visualize nanoplastics bronchial smooth muscle (BSMC) small airway epithelial cells (SAEC), assess impact on mitochondrial metabolism. Healthy asthmatic human BSMC SAEC vitro cultures were stimulated with polystyrene (PS-NPs) of 25 or 50 nm size, for 1 24 h. Live cell, label-free imaging by holotomography microscopy respiration glycolysis assessment performed. Furthermore, NPs shown penetrate SAEC, along healthy diseased BSMC, they impaired bioenergetics induce dysfunction compared not treated NPs, changes oxygen consumption rate extracellular acidification rate. pose a serious threat penetrating tissues cells, affecting both oxidative glycolytic

Polyethylene terephthalate (PET) is one of the most extensively used plastics in daily life. Due to its prevalent use, it ubiquitous environment and a significant contributor plastic pollution. Continuous exposure photochemical, thermal, biological, mechanical processes makes PET susceptible slow degradation production microsized and/or nanosized particles known as microplastic/nanoplastic (MP/NP). MP/NP are widely detected environment, including drinking water human food; consequently, knowledge gaps on impacts food sources have gained global attention. A large gap bioaccumulation fate animals. The application carbon-14 labeled NP animals would provide relatively straightforward approach understanding degree absorption tissue distribution after absorption. Here, simple, fast, efficient synthetic method described produce [14C]-PET NP. comprises polycondensation terephthaloyl chloride readily accessible [14C]-ethylene glycol followed by nanoprecipitation. synthesized were characterized nuclear magnetic resonance spectroscopy (NMR), Fourier transform infrared (FTIR), dynamic light scattering spectroscopy, thermogravimetric analyzer (TGA), UV-Vis spectroscopy.
