Nanostructured materials for efficient microplastic cleanup from soil and water: current trends and future prospects
AI summary Read the abstract
This review evaluates nanostructured materials as tools for removing microplastics from contaminated soil and water environments. Researchers found that engineered nanomaterials, including zinc-based hybrids and carbon-based systems, achieved recovery rates between 80% and 100% under optimized conditions. The study highlights these materials as a promising remediation strategy while noting the need for more realistic testing conditions and scalable approaches.
Microplastics (MPs) and their nano-scale counterparts (Nanoplastics, NPs) have emerged as persistent pollutants in both terrestrial and aquatic environments, posing significant risks to ecological systems and human health. The development of engineered nanomaterials offers a promising path for effective remediation of these contaminants due to their high surface area, catalytic activity, and adaptability. This review provides a comprehensive evaluation of current nanomaterial-based strategies employed for the removal of MPs from soil and aqueous systems. Reported recovery rates for these systems range from 80% to 100%, with zinc-based hybrids demonstrating complete recovery under optimized conditions. More realistic MPs removal comparisons by nanosystems need to be established by experiments in more complex ecologically mimicking habitats. The review also assesses the scalability, material recovery, environmental safety, and operational efficiency of these technologies, which is a novelty of this article. By synthesizing current findings, this study outlines both the technical strengths and existing limitations of nanomaterial-enabled remediation systems, offering insight into future directions for engineered solutions in environmental microplastic mitigation.

Advanced nanocomposites for microplastic remediation: a critical review of materials, mechanisms, and scalability challenges.
AI summary Read the abstract
This review pulls together recent research on special engineered materials (called nanocomposites) designed to filter or break down microplastics in water and the environment—some claim to remove over 99% of microplastics. However, the researchers caution that these impressive numbers come from inconsistent testing methods, meaning we can't yet be sure how well these technologies would actually work in real rivers, oceans, or drinking water systems. This matters because microplastics are increasingly found in our food and water, and knowing which cleanup methods truly work is key to protecting public health—but more standardized, real-world testing is needed before these solutions are ready for widespread use.
Remediation strategies for micro/nanoplastic pollution using magnetic nanomaterials
AI summary Read the abstract
This review surveys recent developments in using magnetic nanomaterials, such as iron oxide nanoparticles and magnetic composites, to remove micro- and nanoplastics from water and soil. These materials can capture plastic particles through adsorption, help clump them together for removal, or even break them down, and they can be magnetically recovered for reuse. The study highlights that magnetic nanomaterials offer a promising approach for cleaning up plastic pollution, though challenges remain in scaling up for real-world use.
