Importance and health hazards of nanoparticles used in the food industry
Bazila Naseer,Gaurav Srivastava,Ovais Shafiq Qadri,Soban Ahmad Faridi,Rayees Ul Islam,Kaiser Younis +5 more
TL;DR: In this paper, the authors present and analyze different studies on the use and the safety of nanoparticles in food and present a review of the literature in terms of the combined analysis of such studies.
Journal ArticleDOI
Copper oxide and zinc oxide nanomaterials act as inhibitors of multidrug resistance transport in sea urchin embryos: their role as chemosensitizers.
TL;DR: It is shown that low concentrations of nano-CuO and nano-ZnO can make embryos more susceptible to other contaminants, representing a potent amplification of nanomaterial-related developmental toxicity.

Preparation and characterization of core–shell polyaniline/mesoporous Cu2O nanocomposites for the photocatalytic oxidation of thiophene
Reda M. Mohamed,Elham S. Aazam +1 more
TL;DR: In this article, polyaniline/mesoporous Cu2O core-shell nanocomposites with different mass ratios of polyani-line and mesoporous CU2O were prepared using a hydrothermal method and the performance of the samples during photocatalytic oxidation of thiophene under visible-light irradiation was determined.

Comparative toxicity and biodistribution assessments in rats following subchronic oral exposure to copper nanoparticles and microparticles
In-Chul Lee,In-Chul Lee,Je-Won Ko,Sung-Hyeuk Park,Na-Rae Shin,In-Sik Shin,Changjong Moon,Je-Hein Kim,Hyoung-Chin Kim,Jong-Choon Kim +9 more
TL;DR: Overall, the in vivo repeated dose toxicity study of Cu NPs and Cu MPs demonstrated that large surface area and high solubility in physiological milieus could directly influence the toxicological responses and biodistribution of Cu particles when administered orally.

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.
