Photochemical transformations of thiolated polyethylene glycol coatings on gold nanoparticles

August 16, 2016
Author(s)
Stacey M. Louie, Justin M. Gorham, Eric A. McGivney, Jingyu Liu, Kelvin B. Gregory, Vincent A. Hackley
Photochemical reactions can result in significant transformations of manufactured nanomaterials in sunlit environments. While transformations of inorganic nanoparticles (NPs) have been investigated extensively, much less attention has been focused on the

Electrospray Differential Mobility Hyphenated with Single Particle Mass Spectrometry for Characterization of Nanoparticles and their Aggregates

August 1, 2016
Author(s)
Jiaojie Tan, Jingyu Liu, Mingdong M. Li, Hind El Hadri, Vincent A. Hackley, Michael R. Zachariah
The hyphenation of electrospray-differential mobility analysis with single particle-inductively coupled plasma mass spectrometry (ES-DMA-spICP-MS) was demonstrated with the capacity for real- time size, mass and concentration measurement of nanoparticles

Orthogonal Analysis of Functional Gold Nanoparticles for Biomedical Applications

September 11, 2015
Author(s)
De-Hao D. Tsai, Yi-Fu Lu, Frank W. DelRio, Tae Joon Cho, Suvajyoti S. Guha, Michael R. Zachariah, Fan Zhang, Andrew J. Allen, Vincent A. Hackley
We report a comprehensive strategy based on implementation of orthogonal measurement techniques to provide critical and verifiable material characteristics for functionalized gold nanoparticles (AuNPs) used in biomedical applications. Thiolated

Fractionation and characterization of high aspect ratio gold nanorods using asymmetric-flow field flow fractionation and single particle inductively coupled plasma mass spectrometry

July 14, 2015
Author(s)
Thao M. Nguyen, Jingyu Liu, Vincent A. Hackley
Development of methods for the in situ fractionation and characterization of high aspect ratio (AR) gold nanorods (GNRs) is a rapidly growing area of interest within the nanotechnology field, particularly with respect to nanomanufacturing and biomedical

Preparation of silver nanoparticle loaded cotton threads to facilitate measurement development for textile applications

January 26, 2015
Author(s)
Justin M. Gorham, Karen E. Murphy, Jingyu Liu, Dimitri Tselenchuk, Gheorghe NMN Stan, Thao M. Nguyen, Richard D. Holbrook, Michael R. Winchester, Robert F. Cook, Robert MacCuspie, Vincent A. Hackley
FOREWORD This NIST special publication (SP) is one in a series of NIST SPs that address research needs articulated in the National Nanotechnology Initiative (NNI) Environmental, Health, and Safety Research Strategy published in 2011 [1]. This Strategy

Accurate determination of the size distribution for polydisperse, cationic metallic nanomaterials by asymmetric-flow field flow fractionation

November 13, 2014
Author(s)
Julien C. Gigault, Thao M. Nguyen, John M. Pettibone, Vincent A. Hackley
In this work we have developed and validated a methodology for determining the size distribution in polydisperse cationic nanoparticle (NP) samples using asymmetric-flow field flow fractionation (A4F), where known compositional influence of previously used

Potential artifacts and misinterpretations when evaluating the ecotoxicological effects of nanomaterials

June 16, 2014
