Interaction of nanoplastics with metronidazole and ciprofloxacin: The Trojan Horse effect.

PLoS ONE
Microplastics 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 ...

Micro- and Nanoplastics and Pulmonary Health: The Current State of Research

Microplastics
Micro- 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 ...

Plastics and Bioplastics End of Life: A Biocatalytic Perspective

Microbial Biotechnology, Volume 19, Issue 8, August 2026.
Biocatalysis links selected conventional plastics and bioplastics to biological routes for polymer transformation, product recovery and end‐of‐life management. Enzymes and microbes enable depolymerisation, upcycling and recovery of monomers, platform chemicals and new materials.

Assessing the Biodistribution and Toxicity of Fluorescently Dyed Nano-Polystyrene in Artemia salina Nauplii

Pollutants
Plastic pollution is a growing environmental crisis, with millions of tons of plastic entering the ocean each year and breaking down into microplastics and nanoplastics.

A Global Review of Microplastic Contamination in Groundwater: Empirical Evidence and Latin American Perspectives

Water and Environment Journal, Volume 40, Issue 3, Page 357-366, August 2026.
ABSTRACT The presence of microplastics (MPs) in groundwater has emerged as a significant concern due to their environmental impact and the threat they pose to vital water resources, groundwater being one of the most important freshwater sources in the world.

Preconcentration of nanoplastics using micro-electromembrane extraction across free liquid membranes

Advances in Sample Preparation
Asymmetric micro-electromembrane extraction (µ-EME) based on a free liquid membrane has been evaluated for the preconcentration of nanoplastics. A conical unit (200 µL micropipette tip) enabled the simple and reproducible formation of the required three ...

Determining the accumulation potential of nanoplastics in crops: An investigation of 14C-labelled polystyrene nanoplastic into radishes

Environmental Research
The capacity of crops to accumulate nanoplastics has remained relatively unexplored largely due to analytical constraints. To address this challenge, the present study employed a radiolabelling approach to demonstrate, for the first time, that polystyrene nanoplastics (14C-PS NPs) accumulate and move into the edible tissues of radishes (Raphanus ...

Impact of polystyrene nanoplastics on the biodegradation of a polyhydroxyalkanoate and its associated biofilm

Environmental Pollution
Biodegradable polymers such as polyhydroxyalkanoates (PHAs) have been proposed as sustainable alternatives to conventional plastics. Their environmental biodegradation is influenced by complex microbial interactions, particularly within biofilms. The presence of nanoplastics in marine environments has unknown impacts on biodegradation processes.
