Anti-adhesion and Anti-biofilm Potential of Organosilane Nanoparticles against Foodborne Pathogens
TL;DR: This study gives an insight to the efficacy of organosilanes based coatings against biofilm formation of foodborne pathogens, however, further studies are needed to better understand the impact of surface modification and the underlying mechanisms which are involved in this phenomenon.
Journal ArticleDOI
Impact of water chemistry on the particle-specific toxicity of copper nanoparticles to Daphnia magna.
TL;DR: It was found that the toxicity of Cu NP(particle) to Daphnia magna, in line with the trends in toxicity for Cu NP (ion), decreased with increasing pH and with increasing concentrations of divalent cations and dissolved organic carbon.
Journal ArticleDOI
Effects of nanosized titanium dioxide on the physicochemical stability of activated sludge flocs using the thermodynamic approach and Kelvin probe force microscopy.
TL;DR: The results showed that the repulsive force predominated the bioflocs system as the concentration of nano-TiO2 increased, owing to the corresponding increase in the density of the negative charge, and these results are the keys for interpreting the adverse effects of nanosized titanium dioxide on the activated sludge flocs of wastewater treatment plant (WWTP).

Effects of CuxTiOy nanometer particles on biological toxicity during zebrafish embryogenesis
Min-Kyeong Yeo,Misook Kang +1 more
TL;DR: CuxTiOy penetrated into the skin, nerve and yolk sac epithelium cells on the zebrafish larvae as aggregated particles, which may induce the direct interaction between nanoparticles and cell to cause adverse biological responses.

Impact of ZnO and ZnS nanoparticles in sewage sludge-amended soil on bacteria, plant and invertebrates.
Patryk Oleszczuk,Patryk Oleszczuk,Bożena Czech,Magdalena Kończak,Aleksandra Bogusz,Anna Siatecka,Paulina Godlewska,Mark R. Wiesner +7 more
TL;DR: The effect of zinc oxide nanoparticles and zinc sulfide nanoparticles on the toxicity of sewage sludges in sewage sludge-amended soils was investigated with respect to plant- and soil- species and there were no significant differences between ZnO and ZnS NPs toxicity towards F. candida.

Nanotoxicology: An Emerging Discipline Evolving from Studies of Ultrafine Particles
TL;DR: Results of older bio-kinetic studies with NSPs and newer epidemiologic and toxicologic studies with airborne ultrafine particles can be viewed as the basis for the expanding field of nanotoxicology, which can be defined as safety evaluation of engineered nanostructures and nanodevices.
Journal ArticleDOI
Probing the Cytotoxicity Of Semiconductor Quantum Dots.
TL;DR: This work found that CdSe-core QDs were indeed acutely toxic under certain conditions and modulated by processing parameters during synthesis, exposure to ultraviolet light, and surface coatings, and suggests that cytotoxicity correlates with the liberation of free Cd2+ ions due to deterioration of the Cd Se lattice.
