Acute Effects of Three Surface Modified Nanoplastics Against Microcystis Aeruginosa: Growth, Microcystin Production, and Mechanisms

Microbial Nanobioremediation of Micro-Nanoplastics: Current Strategies, Challenges, and Future Prospects

AI summary · Read the abstract

Researchers reviewed microbial nanobioremediation strategies — including bacterial biofilm formation, enzymatic degradation, and engineered microbial consortia — for breaking down micro- and nanoplastics in contaminated environments, while cataloging the significant challenges of slow degradation rates and toxicity to the remediating organisms. Developing effective biological cleanup methods is critical because micro- and nanoplastics are too small and widely distributed for mechanical collection, requiring in-situ solutions that work at the molecular level.

Unraveling the Interactions between nanoplastics and biofilms on dense membrane surfaces

Micro-nanoplastics induce the physiological toxicity and metabolic disorder of Bacillus cereus DFH-1

AI summary

Researchers exposed the bacterium Bacillus cereus to micro- and nanoplastics of varying polymer types and sizes, finding that 150 nm PET nanoparticles caused the greatest harm—inhibiting early growth, deforming cell morphology, reducing antioxidant enzyme activity, and broadly disrupting metabolic pathways including the tricarboxylic acid cycle.

Cellular and Animal Toxicities of Micro- and Nanoplastics

AI summary · Read the abstract

Researchers reviewed evidence from cell and animal studies on the toxic effects of micro- and nanoplastics, finding that these particles can cause inflammation, oxidative stress, and organ damage in laboratory models, raising concern about what chronic low-level human exposure might mean for long-term health.

Harnessing Nanomaterials for the Mitigation of Micro-nanoplastics

AI summary · Read the abstract

This review examined how engineered nanomaterials — including metal oxides, carbon-based materials, and zero-valent metals — can photocatalytically degrade, adsorb, or facilitate removal of micro- and nanoplastics from the environment. Nanomaterial-based remediation strategies represent a promising next-generation toolkit for addressing plastic pollution at scales relevant to water treatment and environmental cleanup.
