Nanoplastics and chain-length-dependent PFCs disrupt reproductive endocrinology by targeting the PKC - GnRH signaling axis

Ecotoxicology and Environmental Safety
Nanoplastics (NPs) and microplastics (MPs) are widespread in aquatic ecosystems and frequently co-occurred with perfluorinated compounds (PFCs), yet their combined toxic effects remain poorly understood.

Effect of Polystyrene Nanoplastics on Ovarian Granulosa Cells

International Journal of Biology and Life Sciences
Existing studies have shown that microplastics can cause male reproductive damage, but the effect of nanoplastics on female reproductive ability is rarely studied. The effect of PS-NPs (polystyrene nanoplastics) on the morphology of human granulosa-like tumor cells (KGN) was observed and photographed by optical microscope.

Dysfunctional digestive tract highlights the metabolic hallmarks of nanoplastic-exacerbated Parkinson’s pathology

npj Parkinson's Disease
Parkinson’s disease (PD) is increasingly viewed as both a neurological and metabolic disorder, with the gut-brain axis playing a key role. This study explored how polystyrene (PS) nanoplastics contributed to PD progression by examining their metabolic ...

A comparison of the effects of polystyrene and polycaprolactone nanoplastics on macrophages

Environmental Science: Nano
Plastics are persistent in the environment, which suggests that they may induce adverse effects due to their progressive accumulation over time.

Using a citizen science approach to assess nanoplastics pollution in remote high-altitude glaciers

Scientific Reports
Nanoplastics are suspected to pollute every environment on Earth, including very remote areas reached via atmospheric transport. We approached the challenge of measuring environmental nanoplastics by combining high-sensitivity TD-PTR-MS (thermal ...

Environmentally relevant aged nanoplastics amplify oxidative stress–associated inhalation toxicity and delay lung clearance

Redox Biology
Airborne micro- and nanoplastics are emerging environmental contaminants of increasing concern, yet their inhalation toxicity and pulmonary fate remain insufficiently understood.

Root Meristem Maintenance Mechanisms are Key to Plant Defense Against Nanoplastics

Advanced Science
The pervasive prevalence of nanoplastics in environment poses a challenge that threatens ecosystem and agricultural production. Despite their ubiquity, the determinants of nanoplastics phytotoxicity and the mechanisms through which plants defend against ...

Sensors for Polystyrene Nanoplastics Detection in Water Samples

International Journal of Nanoelectronics and Materials (IJNeaM)
Polystyrene nanoplastics (PS-NPs) are increasingly discovered in aquatic ecosystems, posing ecological and human health problems. Identifying PS-NPs in complex environmental matrices remains difficult due to their small dimension, chemical passiveness, and the existence of background interferences.
