Background-free in-vivo Imaging of Vitamin C using Time-gateable Responsive Probe
TL;DR: A responsive probe for ascorbic acid (vitamin C) has been developed by conjugating two nitroxide radicals with a long-lived luminescent europium complex, suggesting a rational design of lanthanide complexes for background-free small animal imaging of biologically functional molecules.

Investigation of the antibacterial effects of silver-modified TiO2 and ZnO plasmonic photocatalysts embedded in polymer thin films
Szabolcs Péter Tallósy,László Janovák,Judit Ménesi,Elisabeth Nagy,Ádám Juhász,Laszlo Balazs,Istvan Deme,Norbert Buzás,Imre Dékány +8 more
TL;DR: The antibacterial effect of the nanohybrid films has been proven by measuring the decrease of the number of methicillin-resistant S. aureus on the surface and in the air as the function of illumination time.

Photocatalytic oxidation of six endocrine disruptor chemicals in wastewater using ZnO at pilot plant scale under natural sunlight.
Nuria Vela,May Calín,María J. Yáñez-Gascón,Isabel Garrido,Gabriel Pérez-Lucas,José Fenoll,Simón Navarro +6 more
TL;DR: Results carried out at pilot plant scale show that addition of ZnO in tandem with Na2S2O8 strongly enhances degradation rates compared with photolytic test, and photocatalytic oxidation using ZNO is an area of environmental interest for the treatment of polluted water, particularly relevant for Mediterranean countries where solar irradiation is highly available.

Green synthesis of copper oxide nanoparticles: a promising approach in the development of antibacterial textiles
TL;DR: In this article, the synthesis and characterization of nanosized copper oxide nanoparticles (CuONPs) and their application on cotton fabric to increase the bactericidal and hydrophobic properties were reported.
Journal ArticleDOI
Transmission and Accumulation of Nano-TiO2 in a 2-Step Food Chain (Scenedesmus obliquus to Daphnia magna).
TL;DR: The study suggests that nano-TiO2 is mildly toxic to S. obliquus, and can be transferred along the aquatic food chain with a biomagnification effect.

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.
