An experimental nanoparticle developed by Cedars-Sinai Health Sciences University investigators, which delivers cancer treatment directly to tumors in the brain, has been selected for evaluation by the Nanotechnology Characterization Laboratory (NCL).
Finding particles of interest in an air pollution particulate matter sample can be harder than finding a needle in a haystack. It's a time-consuming process that requires scientists to manually locate and scan thousands of microscopic particles across a large sample area, often taking several days.
Solid tumors are not merely collections of malignant cells but complex ecosystems comprising tumor cells, stromal cells, and the extracellular matrix (ECM).
The review examines how engineered nanoparticles and predictive tools, including PK/PD, PBPK, CFD, and AI/ML models, could improve drug delivery across the blood-brain barrier for Alzheimer’s, Parkinson’s, and Huntington’s diseases. It also identifies major barriers to clinical use, including low brain accumulation, long-term safety concerns, model validation, and differences between animal and human biology.
Polyethylene (PE) accounts for about 60% of global plastic waste and persists in soils because of its chemical inertness.
This review examined 27 recent studies on essential-oil nanoemulsions incorporated into biopolymer coatings and films for active food packaging, focusing on barrier properties, antimicrobial activity, sensory effects, and controlled release. The evidence shows that performance depends strongly on nanoemulsion concentration, polymer composition, and formulation design, while scale-up, safety, regulation, and consumer acceptance remain important practical challenges.
A narrative review of two decades of nanotoxicology research shows how particle size, surface chemistry, protein corona formation, exposure conditions, and environmental transformations can shape the biological and ecological effects of nanomaterials. The authors highlight the growing role of AI and machine learning in predictive nanosafety while stressing that standardized testing, high-quality datasets, realistic exposure models, and harmonized regulation remain essential.
The review examined nanoparticle applications in aquaculture from 2020 to early 2026, including antimicrobial treatments, targeted drug and vaccine delivery, disease diagnostics, water remediation, and post-harvest applications. While nanoparticles could improve fish health, water quality, and production efficiency, the authors emphasized that many applications remain experimental and require further field testing and nanoparticle-specific safety assessments.
Biomass-derived green nanomaterials offer a renewable approach to removing persistent pollutants through adsorption, catalytic degradation, and redox reactions while reducing reliance on hazardous synthesis chemicals. The review reports promising removal efficiencies for heavy metals, dyes, and pesticides but highlights unresolved challenges involving scalability, real-world performance, reusability, environmental fate, and nanotoxicity.
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.
