  journal={Journal of Nanoparticle Research},
Characterizing the state of nanoparticles (such as size, surface charge, and degree of agglomeration) in aqueous suspensions and understanding the parameters that affect this state are imperative for toxicity investigations. In this study, the role of important factors such as solution ionic strength, pH, and particle surface chemistry that control nanoparticle dispersion was examined. The size and zeta potential of four TiO2 and three quantum dot samples dispersed in different solutions… 

Characterisation of silica nanoparticles prior to in vitro studies: from primary particles to agglomerates

The size, surface charge and agglomeration state of nanoparticles under physiological conditions are fundamental parameters to be determined prior to their application in toxicological studies.

Preparation and characterization of stable nano-Ag dispersions for nanotoxicological studies

In spite of the increasing importance of manufactured nano materials, only limited information is available on the behavior of their colloidal suspensions (e.g., agglomeration, aggregation and

Role of Surface Area, Primary Particle Size, and Crystal Phase on Titanium Dioxide Nanoparticle Dispersion Properties

The role of particle surface area, primary particle size, and crystal phase on TiO2 nanoparticle dispersion properties is reported andTiO2 isoelectric point was found to be dependent on particle size and insensitive to particle crystal structure.

Aggregation kinetics and surface charge of CuO nanoparticles: the influence of pH, ionic strength and humic acids

Environmental context The high demand and use of nanomaterials in commercial products have led to increased concerns about their effect on the environment and human health. Because CuO nanoparticles

Characterization of nanomaterial dispersion in solution prior to in vitro exposure using dynamic light scattering technique.

It is demonstrated that many metal and metal oxide nanomaterials agglomerate in solution and that depending upon the solution particleagglomeration is either agitated or mitigated.

Characterization of the size, shape, and state of dispersion of nanoparticles for toxicological studies

This paper describes the issues relating to the measurement of nanoparticle size, shape and dispersion when evaluating the toxicity of nanoparticles. Complete characterization of these materials

A comparison of dispersing media for various engineered carbon nanoparticles

It is demonstrated that CNP agglomerates are present in all dispersing vehicles to some degree, and the vehicle that contains some protein, lipid or protein/lipid component disperses the CNP best, producing fewer large CNP Agglomerate, and in contrast, vehicles absent of lipid and protein produce the largest CNPagglomerating.

Aggregation and Deposition Characteristics of Fullerene Nanoparticles in Aqueous Systems

The propensity of n-C60 to aggregate and deposit will play a key role in determining its longevity in aquatic systems, and therefore the potential exposure and risk presented by these colloids. We

Does nanoparticle activity depend upon size and crystal phase?

The ability of different crystal phases of TiO2 nanoparticles to generate ROS was highest for amorphous, followed by anatase, and then anatase/rutile mixtures, and lowest for rutile samples, and important dose metrics for ROS generation are established.

Identification of the Dispersion Behavior of Surface Treated Nanoscale Powders

The stability of highly acidic metal oxide surface treatments on rutile titanium dioxide nanopowders (40 nm nominal particle size) is examined. Dispersions are characterized in terms of their

Improved method to disperse nanoparticles for in vitro and in vivo investigation of toxicity

PBS is not a satisfactory medium to prepare nanoparticle suspensions, however, BALF was an excellent media in which to suspend nanoparticles and PBS-containing protein plus DPPC was satisfactory, although less effective than BALF.

Electrostatic stabilization of ultrafine titania in ethanol

The colloidal stability of a suspension of very fine titania (TiO2) powder in ethanol has been investigated. The electrokinetic behavior and stability ratios were determined as a function of
