Preparation, characterization of NIPAM and NIPAM/BAM copolymer nanoparticles and their acute toxicity testing using an aquatic test battery
Pratap C. Naha,Alan Casey,Tiziana Tenuta,Iseult Lynch,Kenneth A. Dawson,Hugh J. Byrne,Maria Davoren +6 more
TL;DR: The ecotoxicological response was seen to correlate well with the ratio of N-tert-butylacrylamide monomer and therefore with the zeta potential of the nanoparticles, and the derived structure-activity relationships is discussed.

TL;DR: In fish cells, ZnO NP aggregates contributed substantially to the cytotoxic effects whereas toxicity in the human cells appeared to be mainly produced by the dissolved fraction, and ROS production did not contribute to the observed cytotoxicity.

Influence of thickness and coatings morphology in the antimicrobial performance of zinc oxide coatings
Paulo Carvalho,Paula Sampaio,Sofia Azevedo,Catarina Vaz,Juan P. Espinós,Vasco Teixeira,Joaquim A. O. Carneiro +6 more
TL;DR: In this paper, the production of undoped and silver (Ag) doped zinc oxide (ZnO) thin films for food-packaging applications were developed and the main goal was to determine the influence of coatings morphology and thickness on the antimicrobial performance of the produced samples.
Journal ArticleDOI
Evaluation of growth and biochemical indicators of Salvinia natans exposed to zinc oxide nanoparticles and zinc accumulation in plants
TL;DR: ZnO NPs at a concentration of 50 mg L−1 can adversely affect S. natans, and their stress is affected by their aggregation and dissolution, while plant growth was not significantly affected.
Journal ArticleDOI
The potential health risk of titania nanoparticles
TL;DR: This review summarizes relevant reports to support the development of better predictive toxicological models and the safe future application of TNPs.

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.

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.
