Nanoplastics in the Environment: Detection, Toxicological Impact, and Remediation Technologies

Nanoplastics are among the least understood yet fastest-growing sources of environmental contamination. Because they often fall beyond the detection limits of conventional analytical techniques and can readily cross biological barriers, their potential ecological and human health risks remain largely unknown.

This Special Issue welcomes original research articles and reviews addressing all aspects of nanoplastic pollution, including its formation, release, environmental transport, fate, detection, quantification, toxicity, and remediation. Particular emphasis will be placed on materials-based solutions, such as electrochemical and optical biosensors; photocatalytic degradation and advanced oxidation processes; and adsorption and filtration technologies employing advanced nanomaterials, including MXenes, metal-organic frameworks, and functionalized metal oxides.

Contributions focusing on standardized sampling and quantification protocols, green manufacturing strategies to reduce nanoplastic generation at the source, risk assessment, and regulatory frameworks are also encouraged.

By bringing together advances in polymer science, materials chemistry, nanotechnology, environmental engineering, analytical science, and toxicology, this Special Issue aims to consolidate current knowledge, identify critical research gaps, and define future research priorities. We invite contributions from researchers developing practical, scalable, and sustainable solutions to the growing challenge of nanoplastic contamination
