Airborne polystyrene nanoplastic exposure leads to splenic cell senescence and immune imbalance
Ecotoxicology and Environmental SafetyRecently, the widespread detection of microplastics and nanoplastics in the human body and their potential health risks have aroused global concern. As nanoplastics are much smaller than microplastics in diamter, their features, such as larger specific ...

Defecation in preparation for ecdysis drives microplastic clearance in cricket nymphs
Physiological Entomology, EarlyView.In preparation for ecdysis, cricket nymphs cease feeding and gradually clear their gut contents via frass production, which removes most ingested MPs from their digestive tract. Following exoskeletal moulting, the foregut lining, including any remaining MPs, is shed and excreted alongside frass approximately 6 h later.

Interaction of nanoplastics with metronidazole and ciprofloxacin: The Trojan Horse effect.
PLoS ONEMicroplastics and nanoplastics are everywhere, but little is known about their chemical reactivity. In this study we performed a Density Functional Theory study of polystyrene (PS, a common non-biodegradable thermoplastic polymer) and polylactic acid ...

Human placental exposure to pollutant nanoparticles: uptake, translocation and functional impact
The Journal of Physiology, EarlyView.Abstract figure legend Prenatal exposure to pollutant nanoparticles has been increasingly investigated due to concerns about their potential effects on placental function and pregnancy outcomes. Maternal inhalation of pollutant nanoparticles can result in a pro‐inflammatory response; particles can also translocate across the alveolus epithelial barrier

Micro- and Nanoplastics and Pulmonary Health: The Current State of Research
MicroplasticsMicro- and nanoplastics are human made environmental contaminants that pose a growing concern for our health, particularly through airborne exposures. Although human autopsy studies confirm that micro- and nanoplastics are retained in lung tissue, our ...

Law and Ethics of Nanotechnology: Traditional Legal Tools Advancing Nanomedicine
physica status solidi (a), Volume 223, Issue 15, 5 August 2026.Science fiction from the last decades is rapidly becoming science in daily life. For example, nanotechnology does cool things like creating driverless cars for people who are blind and storing solar energy to drive electric cars. Nanotechnology makes possible 3D printing of housing, clothing, and food and miraculous treatments for previously incurable ...
