13. PREPARATION OF NANOPARTICLE DISPERSIONS FROM POWDERED MATERIAL USING ULTRASONIC DISRUPTION
Topic: Nanotech/Environment, Health & Safety
Published: 6/9/2010
Authors: Julian S. Taurozzi, Vincent A Hackley, Mark Wiesner
Abstract: This protocol is generic in nature and intended to provide relevant guidelines for the preparation of nanoparticle dispersions in liquid media by the application of ultrasonic energy. It applies specifically to source engineered nanomaterials (ENM) o ...

14. Predicting Microstructure Development During Casting of Drug Eluting Coatings
Topic: Nanotech/Environment, Health & Safety
Published: 9/19/2010
Authors: David M. Saylor, Jonathan E Guyer, Daniel Wheeler, James A Warren
Abstract: We have devised a novel diffuse interface formulation to model the development of chem- ical and physical inhomogeneities, i.e. microstructure, during the process of casting drug eluting coatings. These inhomogeneities, which depend on the ...

15. Predictive Gold Nanocluster Formation Controlled by Metal-Ligand Complexes
Topic: Nanotech/Environment, Health & Safety
Published: 1/9/2012
Authors: John M Pettibone, Jeffrey W Hudgens
Abstract: The formation of ligand-protected transition metal nanoclusters in size-selective syntheses is driven by the inherent properties of the protecting ligands. We have previously reported the selective, monodisperse product formation of phosphine protect ...

16. Quantifying Dithiothreitol Displacement of Functional Ligands from Gold Nanoparticles
Topic: Nanotech/Environment, Health & Safety
Published: 10/27/2012
Authors: De-Hao D. Tsai, Frank W DelRio, Sherrie R. Elzey, Suvajyoti S. Guha, Michael Russel Zachariah, Vincent A Hackley, Melanie P Shelton
Abstract: Dithiothreitol (DTT)-based displacement is widely utilized for separating ligands from their gold nanoparticle (AuNP) conjugates, a critical step for differentiating and quantifying surface-bound functional ligands and therefore the effective surface ...

17. Quantitative Analysis of Dendron-Conjugated Cisplatin-Complexed Gold Nanoparticles Using Scanning Particle Mobility Mass Spectrometry
Topic: Nanotech/Environment, Health & Safety
Published: 5/8/2013
Authors: De-Hao D. Tsai, Tae Joon Cho, Sherrie R. Elzey, Julien C. Gigault, Vincent A Hackley
Abstract: We report a high-resolution and traceable method to quantify the drug loading on nanoparticle-based cancer therapeutics, and demonstrate this method using a model cisplatin functionalized dendron-gold nanoparticle (AuNP) conjugate. Electrospray diffe ...

18. Separation and Metrology of Nanoparticles by Nanofluidic Size Exclusion
Topic: Nanotech/Environment, Health & Safety
Published: 8/11/2010
Authors: Samuel M Stavis, Jon C Geist, Michael Gaitan
Abstract: A nanofluidic approach to the separation and metrology of nanoparticles is demonstrated. Advantages of this approach include nanometer-scale resolution, nanometer-scale to submicrometer-scale range, mitigation of hydrodynamic and diffusional limitat ...

19. Size Measurement of Nanoparticles using Atomic Force Microscopy
Topic: Nanotech/Environment, Health & Safety
Published: 10/1/2009
Authors: Jaroslaw Grobelny, Frank W DelRio, Pradeep Narayanan Namboodiri, Doo-In Kim, Vincent A Hackley, Robert Francis Cook
Abstract: In this assay protocol, procedures for dispersing gold nanoparticles on various surfaces such that they are suitable for imaging and height measurement via intermittent contact mode AFM are first described. The procedures for AFM calibration and ope ...

20. Surface mediated assembly of small, metastable gold nanoclusters
Topic: Nanotech/Environment, Health & Safety
Published: 5/27/2013
Authors: John M Pettibone, William A Osborn, Konrad Rykaczewski, Albert A. Talin, John E Bonevich, Jeffrey W Hudgens
Abstract: The unique properties of metallic nanoclusters are attractive for numerous commercial and industrial applications but are generally less stable than nanocrystals. Thus, developing methodologies for stabilizing nanoclusters and retaining their enhance ...
