The effects of engineered coatings and natural organic matter on nanoparticle aggregation

Creator:

McDowell, Shannon A.

Abstract:

In order to better predict the aggregation state of nanomaterials, the factors that influence aggregation must be understood. The combined effects of natural and engineered coatings have been shown to factor into nanoparticle aggregation behavior in preliminary research. In this study, aggregation behaviors of gold nanoparticles with two different engineered...

Interactions between natural organic matter and gold nanoparticles stabilized with different organic capping agents

Creator:

Stankus, Dylan Paul

Abstract:

The adsorption of natural organic matter (NOM) to the surfaces of natural colloids and engineered nanoparticles is known to strongly influence, and in some cases control, their surface properties and aggregation behavior. As a result, the understanding of nanoparticle fate, transport and toxicity in natural systems must include a fundamental...
