Unlocking nanoplastic removal from landfill leachate - a dual-layer adsorptive PES@PMACZ@MOF & repulsive self-assembled mesoporous silica modified matrix membrane
AI summary Read the abstract
Scientists developed a new filter membrane that can remove almost all micro- and nanoplastics (98.8% to 100%) from landfill wastewater, tiny plastic particles that can leach into groundwater and eventually end up in our drinking water and food supply. This filter is special because it stays effective over repeated use, resists clogging, and works well across different water conditions, making it a promising tool for cleaning up plastic pollution before it spreads further into our environment and bodies.
• PMACZ 20 /SAM-DMS 3 N 2 nanopore membrane achieved 98.8 % nanoplastic and 100 % microplastic rejection in SLL. • PMACZ 20 /SAM-DMS 3 N 2 membrane maintained 81 % normalized flow after 24 h, demonstrating strong antifouling resistance. • PMACZ 20 /SAM-DMS 3 N 2 membrane sustained over 98.8 % NPs rejection across five filtration cycles without chemical cleaning. • PMACZ 20 /SAM-DMS3N 2 membrane enabled up to 93 % MPs and 50 % NPs release, confirming effective physical regeneration. • PMACZ 20 /SAM-DMS 3 N 2 nanopore membrane exhibited stable rejection performance across pH 2–10, with peak efficiency at pH of 7.

Fabrication of dual-charged MOF-based ultrafiltration membrane to remove charged nanoplastics from wastewater
AI summary Read the abstract
Researchers developed a new type of water filter membrane that can remove over 99% of nanoplastics from wastewater while maintaining high water flow. The membrane uses metal-organic framework nanoparticles that repel plastic particles through electrical charges and physical filtering. This technology could help prevent nanoplastics, which are too small for conventional filters, from reaching drinking water sources.
pH-responsive mixed-charge ultrafiltration membranes for adaptive control of single and mixed nanoplastic fouling
AI summary Read the abstract
Scientists engineered a new type of water filter membrane that resists clogging from nanoplastics, tiny plastic particles too small to see that are increasingly found in drinking water. By coating the filter with a special material that switches its electrical charge depending on water conditions, they created a self-cleaning surface that blocked over 95% of nanoplastics while staying easier to rinse clean than standard filters. This matters because more effective, longer-lasting water filters could help reduce our exposure to nanoplastics, which scientists are still studying for potential health effects.

Researchers created an advanced membrane filter using metal-organic framework nanoparticles that removed over 99% of nanoplastics from water while maintaining high water flow rates. The membrane resisted fouling and worked reliably across multiple cycles and different water conditions. This type of technology could improve wastewater treatment plants' ability to prevent nanoplastics from reaching drinking water supplies.
Biobased Composite Aerogels for Efficient Flow-Through Capture of Nanoplastics via Multimodal Interfacial Interactions
AI summary Read the abstract
Scientists created a new sponge-like filter made from natural materials that can remove nearly 100% of tiny plastic particles from water. These nanoplastics are so small they're invisible to the naked eye but pose potential health risks when they get into drinking water. The filter works efficiently with very little energy, offering a promising way to clean up water contaminated with plastic pollution.
Dual metal-organic framework composite – Polyethersulfone hybrid hollow fiber membranes for effective elimination of microplastics and toxic contaminants from wastewater via ultrafiltration
AI summary Read the abstract
Scientists developed a new water-filtering material that can remove up to 97% of microplastics, along with toxic dyes and heavy metals like lead and mercury, from contaminated water. This matters because current water treatment methods often struggle to catch these tiny plastic particles and pollutants, which can build up in our bodies over time; this new filter could offer a cheaper, more effective way to clean drinking water and protect public health.
