Toxicity of silver nanoparticles—Nanoparticle or silver ion?
Toxicology Letters, 2012The toxicity of silver nanoparticles (AgNPs) has been shown in many publications. Here we investigated to which degree the silver ion fraction of AgNP suspensions, contribute to the toxicity of AgNPs in A549 lung cells. Cell viability assays revealed that AgNP suspensions were more toxic when the initial silver ion fraction was higher.

Toxicity of CeO2 nanoparticles – The effect of nanoparticle properties
Journal of Photochemistry and Photobiology B: Biology, 2015Conflicting reports on the toxicity of CeO2 nanomaterials have been published in recent years, with some studies finding CeO2 nanoparticles to be toxic, while others found it to have protective effects against oxidative stress. To investigate the possible reasons for this, we have performed a comprehensive study on the physical and chemical properties ...

AbstractUpconversion (UC) refers to nonlinear optical processes in which the sequential absorption of two or more photons leads to the emission of light at shorter wavelength than the excitation wavelength (anti‐Stokes type emission). In contrast to other emission processes based on multiphoton absorption, upconversion can be efficiently excited even ...

Electrochemistry of Nanoparticles
Angewandte Chemie International Edition, 2014AbstractMetal nanoparticles (NPs) find widespread application as a result of their unique physical and chemical properties. NPs have generated considerable interest in catalysis and electrocatalysis, where they provide a high surface area to mass ratio and can be tailored to promote particular reaction pathways.

Nano-structured semiconductors, a new class of particles emerged as a good candidate for applications, especially in electronics, optoelectronics and biology because they can bridge the gap between the bulk and molecular levels. They have size-tunable optical and electronic properties, very high available surface area and optical transparency. They can
