11. Fluorinated Copolymer Nanoparticles for Multimodal Imaging Applications
Topic: Nanobiotechnology
Published: 2/18/2010
Authors: Mark M. Bailey, Christine M. Mahoney, Elodie Dempah, Jeffrey M Davis, Matthew Becker, Supang Khondee, Eric J. Munson, Cory J. Berkland
Abstract: Nanomaterials have emerged as valuable tools in biomedical imaging techniques, such as magnetic resonance imaging (MRI), fluorescence, positron emission tomography (PET), and others. Some have been designed to serve as multimodal imaging agents, com ...

12. Fractionation and Characterization of Gold Nanoparticles in Aqueous Solution: Asymmetric-Flow Field Flow Fractionation with MALS, DLS and UV-Vis Detection
Topic: Nanobiotechnology
Published: 8/30/2010
Authors: Tae Joon Cho, Vincent A Hackley
Abstract: Asymmetrical-flow field flow fractionation (AFFF) separates constituents based on hydrodynamic size, and is emerging as a powerful tool for obtaining high-resolution information on the size, molecular weight, composition, and stability of nanoscale p ...

14. Methodology for imaging of nano-to-microscale water condensation dynamics on complex nanostructures
Topic: Nanobiotechnology
Published: 6/11/2011
Authors: Konrad Rykaczewski, John Henry j Scott
Abstract: By transferring of a small part of a macroscale sample to a novel thermally insulated sample platform we are able to mitigate flooding and electron heating problems typically associated with Environmental Scanning Electron Microscopy imaging of water ...

15. Microfabricated High-Moment Micrometer-Sized MRI Contrast Agents
Topic: Nanobiotechnology
Published: 8/26/2010
Authors: Gary Zabow, John M Moreland, Stephen Dodd, alan koretsky, erik shapiro
Abstract: While chemically synthesized superparamagnetic microparticles have enabled much new research based on MRI tracking of magnetically labeled cells, signal-to-noise levels still limit the potential range of applications. Here it is shown how, through to ...

16. Microfluidic Remote Loading for Rapid Single-Step Liposomal Drug Preparation
Topic: Nanobiotechnology
Published: 7/29/2014
Authors: Wyatt N Vreeland, Renee R Hood, Don L. DeVoe
Abstract: Here we report a microfluidic system that enables rapid and efficient remote loading of amphipathic drugs into nanoscale liposomes, combining liposome synthesis and remote drug loading in a continuous integrated process. Unlike established bulk m ...

17. Microfluidic preparation of liposomes to determine particle size influence on cellular uptake mechanisms
Topic: Nanobiotechnology
Published: 10/3/2013
Authors: Wyatt N Vreeland, Abhay U Andar, Renee R Hood, Don L. DeVoe, Peter W Swaan
Abstract: Purpose: This study investigates the cellular uptake and trafficking of liposomes in Caco-2 cells, using vesicles with distinct average diameters ranging from 40 nm-276 nm. Liposomes were prepared by microfluidic hydrodynamic flow focusing, producing ...

18. Microfluidic-Enabled of Liposomes Elucidate Size-Dependent Transdermal Transport
Topic: Nanobiotechnology
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 ...

19. N-methylmesoporphyrin IX fluorescence as a reporter of strand orientation in guanine quadruplexes
Topic: Nanobiotechnology
Published: 4/1/2014
Authors: Navin C. Sabharwal, Victoria Savikhin, Joshua Turek-Herman, John M. Nicoludis, Veronika A Szalai, Liliya Yatsunyk
Abstract: Guanine quadruplexes (GQ) are four-stranded DNA structures formed by guanine-rich DNA sequences. Formation of GQs inhibits cancer cell survival, but detecting GQs in vivo has proved difficult, in part because of GQ structural diversity. Development ...

20. Nanometrology Using Through-Focus Scanning Optical Microscopy Method
Topic: Nanobiotechnology
Published: 12/21/2011
Authors: Ravikiran (Ravikiran) Attota, Richard M Silver
Abstract: We present an initial review of a novel through-focus scanning optical microscopy (TSOM) imaging method that produces nanometer dimensional measurement sensitivity using a conventional bright-field optical microscope. In the TSOM method a target is ...
