A New Separation Metric for the Optimization of AF4 Separations of Polydispersed Nanomaterials

Galyean A.A., Vreeland W.N., Filliben J.J., Holbrook R.D., Weinberg H.S., University of North Carolina at Chapel Hill, US

The development of standardized and optimized methods to monitor the behavior of engineered nanomaterials (ENMs) in complex environments is considered a critical component in ENM risk assessment. Robust, rigorously optimized methods are currently lacking, in [...]

Surface Chemical Transformations of UV Irradiated Silica-Epoxy Nanocomposites

Gorham J.M., Nguyen T., Bernard C., Stanley D., Holbrook R.D., National Institute of Standards and Technology, US

Silica nanoparticles (SiNPs) incorporated into a polymeric matrix, or silica nanocomposites (NCs), are used in a wide variety of commercially available products in numerous natural and artificial environments. Environmental factors, such as ultraviolet (UV) light, [...]

Quantum Dot Dissemination and Behavior in Bacterial Biofilms

Morrow J.B., Holbrook R.D., Zeissler C.J., National Institute of Standards and Technology, US

Quantum dots (QDs) are colloidal semiconductor nanocrystals that photoluminescence emission is proportional to the dot size and have been utilized in fluorescent imaging in biological systems. Biofilms are communities of microorganisms attached to surfaces encased [...]
