21. Microfluidic-Enabled of Liposomes Elucidate Size-Dependent Transdermal Transport
Topic: Drugs/Pharmaceuticals
Published: 3/21/2014
Authors: Wyatt N Vreeland, Renee R Hood, Eric Kendall, Don L. DeVoe, Julia Finkel, Mariana Junqueira, Zenaide Quezado
Abstract: Microfluidic synthesis of small and nearly-monodisperse liposomes is used to investigate the size-dependent passive transdermal transport of nanoscale lipid vesicles. While large liposomes with diameters above 105 nm are found to be excluded from dee ...

23. NIST/NIH Vitamin D Metabolites Quality Assurance Program Report of Participant Results:Summer 2010 (Exercise 2)
Series: NIST Interagency/Internal Report (NISTIR)
Report Number: 7891
Topic: Drugs/Pharmaceuticals
Published: 12/21/2012
Authors: Katrice A Lippa, Mary Bedner, Susan Shu Cheng Tai
Abstract: The National Institute of Standards and Technology (NIST) recently established a Vitamin D Metabolites Quality Assurance Program (VitDQAP) in collaboration with the National Institutes of Health (NIH) Office of Dietary Supplements. Participants ...

24. Predictive Gold Nanocluster Formation Controlled by Metal-Ligand Complexes
Topic: Drugs/Pharmaceuticals
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 ...

25. Probing the Nature of Ibuprofen Confined in Mesoporous Media by Neutron Vibrational Spectroscopy and First-Principles Calculations
Topic: Drugs/Pharmaceuticals
Published: 5/15/2012
Author: Ken Kangyi Qian
Abstract: {B}Purpose{/B}: In this paper, the nature of ibuprofen incorporated into both mesoporous silicon dioxide and magnesium aluminometasilicate by sublimation and adsorption was investigated using neutron vibrational spectroscopy. {B}Methods{/B}: Crystall ...

26. Quantification of Drugs of Abuse in Municipal Wastewater via SPE and Direct Injection Liquid Chromatography Mass Spectrometry
Topic: Drugs/Pharmaceuticals
Published: 9/24/2010
Authors: Michele Miller Schantz, Katrice A Lippa, Kevin Bisceglia, A. Lynn Roberts
Abstract: We present an isotopic dilution direct injection reverse phase liquid chromatography-tandem mass spectrometry (RPLC/MS/MS) method for the simultaneous determination of 23 drugs of abuse, drug metabolites, and human use markers in municipal wastewater ...

27. Quantifying Dithiothreitol Displacement of Functional Ligands from Gold Nanoparticles
Topic: Drugs/Pharmaceuticals
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 ...

28. Quantitation of HER2 and Telomerase Biomarkers in Solid Tumors with IgY Antibodies and Nanocrystal Detection
Topic: Drugs/Pharmaceuticals
Published: 5/15/2008
Authors: Yan Xiao, X Gao, G Gannot, M Emmert-Buck, S Srivastava, Paul D Wagner, Michael D. Amos, Peter E. Dr. Barker

29. Quantitative Analysis of Dendron-Conjugated Cisplatin-Complexed Gold Nanoparticles Using Scanning Particle Mobility Mass Spectrometry
Topic: Drugs/Pharmaceuticals
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 ...

30. Recent Advances in Electrochemical Glyco-biosensing
Topic: Drugs/Pharmaceuticals
Published: 4/8/2011
Authors: Rebecca A Zangmeister, Germarie Sanchez-Pomales
Abstract: Biosensors based on electrochemical transduction mechanisms have recently made advances into the field of glycan analysis. These glyco-biosensor assays offer simple, rapid, sensitive and economical approaches to the measurement need for rapid glycan ...
