Nano-Bio Interface in Environmental Systems

The rapid expansion of nanotechnology and the growing presence of micro- and nanoplastics, have created a need to better understand nano–bio interfaces. This dynamic governs how nanomaterials interact with microorganisms, plants, and other biological systems. Elucidating these mechanisms is essential for predicting environmental transport, fate, bioavailability, uptake, biological effects, and bioaccumulation. Conversely, understanding and controlling nano–bio interactions can support the development of advanced nanomaterials for air and water treatment and environmental remediation. This Research Topic connects fundamental interfacial science with environmental risk assessment and nanotechnology-enabled solutions. Priority is given to real-world exposure models, standardized nanomaterial characterization, environmental fate, and Equity, Diversity, and Inclusion (EDI)-informed research design. This collection highlights cutting-edge research aimed at developing reproducible, safe, and socially responsible environmental solutions that are rigorous, comprehensive, and responsive to the diverse communities and environments affected by nanotechnology.The environmental presence of nanomaterials is growing at an unprecedented rate. Even engineered nanomaterials designed for beneficial applications—alongside incidental pollutants like micro- and nanoplastics—may accumulate or have significant residence time across soil, water, and air. Deepening our understanding of how these persistent entities interact with both living organisms and abiotic components of the environment is essential for developing effective strategies to mitigate their long-term impact. Addressing this complex challenge requires an inherently collaborative effort across disciplines. To develop meaningful solutions, we must commit to producing technologies that are accessible, cost-efficient, and respectful of both the environment and local communities. Embedding Equity, Diversity, and Inclusion (EDI) from the outset of research design is central to this collection. Integrating diverse perspectives ensures that our scientific frameworks, risk assessments, and technological innovations deliver equitable, safe, and sustainable outcomes for society as a whole.We welcome contributions on the following topics:• Toxicity and Biological Interactions: Effects of engineered nanoparticles and nanoplastics on bacteria, cellular uptake mechanisms, plant dynamics, and physiology using real-life exposure models.• Nanotechnology for Water, Air, and Soil Remediation: Green chemistry-synthesized nanomaterials for water and wastewater treatment, including pollutant degradation and filtration; air remediation through removal of greenhouse gases and volatile organic compounds; and soil remediation through contaminant immobilization, degradation, or removal while protecting soil health and microbial communities.• Environmental Fate: Long-term ecological impacts, bioaccumulation pathways, and material behavior in soil, water, and air. • Standardization and Reproducibility: Methodologies that advance the use of standardized, thoroughly characterized nanomaterials and harmonized testing approaches to improve reproducibility, comparability, and reliability across studies.Authors are expected to state integration of EDI principles throughout the research process.We welcome Original Research, Review and Mini Review articles, Methods, Perspectives, and Brief Research Reports.
