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.

An Edible Biohybrid Platform Accomplishes In Situ Fenton‐Mediated Enteral Nanoplastics Aging and Excretion

Advanced Science, EarlyView.
An edible biohybrid platform triggers nanoplastics (NPs) aging and agglomeration by in situ generating hydroxyl radicals within the intestine. The enlarged NPs are unable to penetrate the intestine and are subsequently excreted. Simultaneously, probiotic biofilms reinforce the intestinal barrier.

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.

Microplastics‐Induced Gut Microbiota Dysbiosis Accelerates Alzheimer's‐Like Pathology and Cognitive Decline via the Gut–Brain Axis

Advanced Science, EarlyView.
Microplastics (MPs) breach the gut‐brain axis by triggering taurine‐depleting microbiota dysbiosis that accelerates Alzheimer‐like pathology in 5XFAD mice. Taurine supplementation normalizes autophagy, microglial quiescence, and cognition, and plasma taurine inversely tracks cognitive decline in ADNI participants, revealing a readily translatable ...

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

Nanoplastics in Duckweed: Single-Cell Responses and Recovery

ACS Nano
Micro- and nanoplastics have emerged as critical contaminants in aquatic ecosystems due to their small size, persistent nature, and potential for bioaccumulation. Nanoplastics are particularly concerning because they can be widespread in aquatic environments and ingested by aquatic organisms, posing potential risks to ecological health and ...

Deep‐Learning‐Driven High‐Fidelity In Vivo Hyperspectral Fluorescence Imaging Under Extreme Photon‐Limited Conditions

Advanced Science, EarlyView.
Highly overlapping fluorescent signals become distinguishable in photon‐limited living organisms via advanced imaging with intelligent reconstruction. The resulting in vivo hyperspectral imaging capability reveals nanoplastic uptake and circulation in live zebrafish, providing a new approach for studying complex biological and environmental processes ...

Nanoplastics exposure-induced mitochondrial dysfunction contributes to disrupted stem cell differentiation in human cerebral organoids

Ecotoxicology and Environmental Safety
Nanoplastics are ubiquitous in our daily lives, raising concerns about their potential impact on the human brain. Many studies reported that nanoplastics permeate the blood-brain barrier and influence cellular processes in mouse models.

Presence of microplastics and nanoplastics in food, with particular focus on seafood

EFSA Journal, 2016
Following a request from the German Federal Institute for Risk Assessment (BfR), the EFSA Panel for Contaminants in the Food Chain was asked to deliver a statement on the presence of microplastics and nanoplastics in food, with particular focus on ...
