Current Medicinal Chemistry, 2014
Nowadays more than thousands of different nanoparticles are known, though no well-defined guidelines to evaluate their potential toxicity and to control their exposure are fully provided. The way of entry of nanoparticles together with their specificities such as chemistry, chemical composition, size, shape or morphology, surface charge and area can ...

Dielectrophoresis of Nanoparticles
Fluids Engineering, 2004A numerical scheme based on the distributed Lagrange multiplier method (DLM) is used to study the motion of nano sized particles of dielectric suspensions subjected to uniform and nonuniform electric fields. Particles are subjected to both electrostatic and hydrodynamic forces, as well as Brownian motion.

Magnetophoresis of Nanoparticles
ACS Nano, 2010Iron oxide cores of 35 nm are coated with gold nanoparticles so that individual particle motion can be tracked in real time through the plasmonic response using dark field optical microscopy. Although Brownian and viscous drag forces are pronounced for nanoparticles, we show that magnetic manipulation is possible using large magnetic field gradients ...

Wetting of nanoparticles and nanoparticle arrays
Colloids and Surfaces A: Physicochemical and Engineering Aspects, 2002Abstract We report investigations of nanoparticulate wetting carried out using molecular dynamics simulations. Despite their small size, model ‘Lennard–Jones’ nanoparticles in simple Lennard–Jones solvents exhibit well defined contact angles, which for high surface tension interfaces have been shown to obey Young's equation with surprising accuracy ...

Electrochemistry of Nanoparticles [PDF]
Angewandte Chemie International Edition, 2014 AbstractMetal 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.

Bulletin of Environmental Contamination and Toxicology, 2019
Metal dioxide nanoparticles (NPs) are produced in ever-increasing amounts and widely used in industrial, medical and consumer products. They may pose potential risks to the environment. In this study we quantitatively evaluated the phytoavailability of CeO2NPs, ZrO2NPs and SiO2NPs to wheat (Triticum aestivum L.).

Characterization of Nanoparticles [PDF]
Materials Science Forum, 1999 AbstractNanoparticles with diameters from 1–100 nm are used in large quantities for very different applications. A precise determination of the important physical quantities (which are responsible for the application properties) such as diameter, particle size distribution, and surface is therefore very essential.
