Are Microplastics Toxic? A Review from Eco-Toxicity to Effects on the Gut Microbiota

Metabolites, 2023
Emerging studies have presented an initial picture of the toxic effects of exposure to environmental micro- and nanoplastics. They have indicated that micro- and nanoplastics may induce toxicity by leading to oxidative stress, energy metabolism disorders,

Multilayer Biobased Poly(ethylene furanoate)/Graphene Oxide Nanofibrous Membranes With Directional Water Transport for Efficient Microplastics Filtration

Advanced Materials Technologies, EarlyView.
A self‐assembled multilayer biobased PEF/GO nanofibrous membrane was developed by electrospinning for efficient PLA microplastics (MPs) filtration. The membrane combines superhydrophilicity, directional water transport, mechanical robustness, and a synergistic size‐exclusion interception and electrostatic repulsion MPs separation mechanism, enabling ...

Nanoplastics and the marine environment: The unseen majority?

, 2022
Nanoplastics can be classified into primary and secondary nanoplastics, where primary nanoplastics are industrially produced for specific purposes and secondary nanoplastics result from plastic waste via degradation processes.

Nanoplastics causes heart aging/myocardial cell senescence through the Ca2+/mtDNA/cGAS-STING signaling cascade

Journal of Nanobiotechnology
Background Nanoplastics (NPs) are now a new class of pollutants widely present in the soil, atmosphere, freshwater and marine environments. Nanoplastics can rapidly penetrate cell membranes and accumulate in human tissues and organs, thus posing a ...

Polystyrene Nanoplastics Drive β‐Cell Dedifferentiation Through Dendritic Cell‐Intrinsic MHC‐I‐Dependent Inflammatory Crosstalk

Advanced Science, EarlyView.
Polystyrene nanoplastics disrupt pancreatic immune–endocrine homeostasis by promoting MHC‐I‐associated dendritic cell activation and inflammatory crosstalk with β cells. This immune remodeling drives β‐cell dedifferentiation, impairs insulin secretion, and aggravates metabolic dysfunction, revealing a previously unrecognized immunometabolic mechanism ...

Nanoplastics and Neurodegeneration in ALS

Brain Sciences
Plastic production, which exceeds one million tons per year, is of global concern. The constituent low-density polymers enable spread over large distances and micro/nano particles (MNPLs) induce organ toxicity via digestion, inhalation, and skin contact. Particles have been documented in all human tissues including breast milk.

Titanium-doped PET nanoplastics of environmental origin as a true-to-life model of nanoplastic

Science of The Total Environment, 2023
يتطلب الوجود المتزايد للمواد البلاستيكية الدقيقة/النانوية الثانوية (MNPLs) في البيئة دراسات عاجلة حول آثارها الخطرة المحتملة على الكائنات الحية المكشوفة، بما في ذلك البشر. في هذا السياق، من الضروري الحصول على عينات تمثيلية من MNPL لهذه الأغراض. في دراستنا، حصلنا على NPLs حقيقية ناتجة عن التحلل، عن طريق الصنفرة، لزجاجات البولي إيثيلين تيرفثالات المعتمة.

Deep Learning‐Driven Discovery and Engineering of an Efficient PETase for Depolymerization and Detoxification of PET Microplastics Under Physiological Conditions

Advanced Science, EarlyView.
A deep learning–driven pipeline mining 246 million protein sequences uncovers AhPETase, an evolutionarily distinct PET hydrolase. Engineered variant AhPETaseM1 degrades post‐consumer PET microplastics under physiological conditions and reverses microplasticinduced cytotoxicity in human lung and colon cells, establishing enzymatic microplastic ...

Nanoplastics Enhance Transmembrane Transport and Uptake of Carcinogens: Transcriptional Changes and the Effects of Weathering

Advanced Science
Nanoplastics are generated from common consumer plastics (polyethylene terephthalate, high‐density polyethylene, polystyrene, polyvinyl chloride) and exposed to simulated marine weathering for up to 10 weeks. Fourier‐transform infrared spectroscopy and ζ‐

Can Micro/Nanoplastics Influence PM2.5 Characteristics: An Ex Situ Investigation by Physicochemical Indicators of PM2.5 and Their Bacterial Model Toxicity

Microplastics
Exposure to PM2.5 and its associated micropollutants, including micro- and nanoplastics, has been strongly linked to adverse health effects in humans. The risk posed by micro/nanoplastics can be attributed to the particles themselves and their ability to
