Researchers developed magnetically driven 2D MXene microrobots that capture and retrieve PS and PET microplastics from laboratory water and soil samples. In 60-minute tests, the microrobots removed up to 94.0% of microplastics from water and 80.6% from soil, but nickel leakage and incomplete recovery require further study.
A systematic review of 212 studies linked experimental exposure to microplastics and nanoparticles to oxidative stress, impaired growth and reproduction, and increased mortality across biological models. Smaller particles, higher concentrations, and polystyrene were associated with stronger effects, although laboratory conditions and limited human evidence restrict conclusions about real-world health risks.
Scientists reported the first evidence of nanoplastics in mainland Antarctic soil, detecting multiple polymers in samples from the McMurdo Dry Valleys. The findings suggest Antarctica’s remote terrestrial ecosystems are exposed to plastic contamination from local sources and long-range atmospheric transport.
This review proposes eco-nanozymology as a framework for designing nanozymes that act as catalytic regulators in energy conversion, pollutant degradation, biomass valorization, and biogeochemical cycling. It highlights progress in nanozyme design while emphasizing that real-world safety, environmental fate, scalability, and regulatory oversight remain major challenges.
Researchers developed a semi-quantitative probability-impact framework to prioritize engineered nanoparticles and micro/nanoplastics in agri-food systems based on exposure potential, toxicity evidence, and uncertainty. Across weighting scenarios, silver, titanium dioxide, zinc oxide, carbon nanotubes, cerium dioxide, and copper oxide emerged as high-priority particles for targeted monitoring and refined toxicological assessment.
