Evaluation of toxicity and oxidative stress induced by copper oxide nanoparticles in the green alga Chlamydomonas reinhardtii.
Silvia Pedroso Melegari,François Perreault,Rejane Helena Ribeiro da Costa,Radovan Popovic,William Gerson Matias +4 more
TL;DR: Copper oxide nanoparticles (CuO NP) was found to induce growth inhibition and a significant decrease in carotenoids levels and Chlamydomonas reinhardtii was shown to be sensitive to the presence of CuO NP in their environment.

Critical Review on the Toxicity of Some Widely Used Engineered Nanoparticles
TL;DR: In this paper, the authors have shown that nanoparticles have shown major toxic effects on fauna, flora, and human beings, such as inflammation, cytotoxicity, tissue ulceration, and reduction of cell viability.

Toxicity of silver and copper to Cucurbita pepo: differential effects of nano and bulk-size particles.
Craig Musante,Jason C. White +1 more
TL;DR: The data demonstrate differential toxicity of Ag NP relative to bulk Ag and the finding that humic acid and solution chemistry differentially impact bulk and NP behavior highlights the importance of evaluating nanoparticles under environmentally relevant conditions.

Cu and CuO nanoparticles immobilized by silica thin films as antibacterial materials and photocatalysts
Omid Akhavan,Elham Ghaderi +1 more
TL;DR: In this article, it was found that the lower antibacterial activity of the reduced thin films was assigned to diffusion of the initially accumulated copper-based nanoparticles into the film, while the CuO nanoparticles also exhibited a slight photocatalytic activity for inactivation of the bacteria.

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.
