Interactions between titanium dioxide nanoparticle exposure and grazing organisms on periphyton biomass and community composition.
Titanium dioxide nanoparticles (TiO₂NPs) are important contaminants of emerging concern, due to their ubiquity and use in such a broad range of consumer products. Freshwater ecosystems represent the most important aquatic reservoir for TiO₂NPs. Outdoor stream mesocosm and indoor stream microcosm …

Aerosol Route Synthesis and Applications of Doped Nanostructured Materials
… phase) were independently controlled based on nanoparticle formation and growth mechanisms dictated by process control parameters. Copper dopant found to significantly affect TiO2 properties such as particle size, crystal phase, stability in the suspension, and absorption spectrum: shift from …

Characterization of Biomedical and Incidental Nanoparticles in the Lungs and Their Effects on Health
… highly desirable site to administer therapeutic nanoparticles. Indeed, inflammatory diseases such as asthma and emphysema could potentially benefit from nanoparticle-mediated delivery. However, the lungs are also in constant contact with airborne particulate matter. Thus, harmful nanoparticles …

Nanoparticle toxicokinetics in the nose: an assessment of risk
… relate the ’delivered dose’, i.e. the number of nanoparticles reaching immortalized airway cell layers by gravitational force and diffusional mechanisms, to toxicological endpoints measured in vitro. This model was applied to a panel of rigorously characterized nanoparticles (CuO, TiC>2, …

Mycobacterium tuberculosis metallomics
… This study investigated the role of metal-based nanoparticles as potential antimycobacterial agents. Superparamagnetic iron oxide nanoparticles (SPIONs) were synthesised via co-precipitation of ferric chloride and ferric sulphate. The SPIONs were subsequently surface modified with secondary …

Assessing the Impacts of Silver Nanoparticles on the Growth, Diversity, and Function of Wastewater Bacteria
<p>Silver nanoparticles (AgNPs) are increasingly being integrated into a wide range of consumer products, such as air filters, washing machines, and textiles, due to their antimicrobial properties [1]. However, despite the beneficial applications of AgNPs into consumer products, it is likely that …
