1. A Facile Route to the Synthesis of Monodisperse Nanoscale Liposomes Using 3D Microfluidic Hydrodynamic Focusing in a Concentric Capillary Array
Topic: Nanobiotechnology
Published: 5/14/2014
Authors: Wyatt N Vreeland, Renee R Hood, Don L. DeVoe, Francisco Javier Atencia, Donna M. Omiatek
Abstract: A novel microscale device has been developed to enable the one-step continuous flow assembly of monodisperse nanoscale liposomes using three-dimensional microfluidic hydrodynamic focusing (3D-MHF) in a radially symmetric capillary array. The 3D-M ...

2. A method to determine the number of nanoparticles in a cluster using conventional optical microscopes
Topic: Nanobiotechnology
Published: 9/10/2015
Authors: Hyeong Gon (Hyeonggon) Kang, Ravikiran Attota, Premsagar Purushotham Kavuri, Vipin Nagnath Tondare, Andras Vladar

3. Carbon Nanotubes Activate Store Operated Calcium Entry (SOCE) in Blood Platelets Manifested by STIM-1 Clustering
Topic: Nanobiotechnology
Published: 6/3/2011
Authors: Silvia Helena De Paoli Lacerda, Jana Semberova, Karel Holada, Olga Simakova, Steven D Hudson, Jan Simak
Abstract: Intravascular effects of carbon nanotubes (CNTs) as a result of their various biomedical applications or environmental/occupational exposure raise serious safety concerns. CNTs potentiate arterial thrombosis in animal models;[1, 2] however, a mechani ...

4. Changes in Ion Channel Geometry Resolved to Sub-angstrom Levels via Single Molecule Mass Spectrometry
Topic: Nanobiotechnology
Published: 10/29/2010
Authors: Joseph William Robertson, John J Kasianowicz, Joseph E. (Joseph E.) Reiner

5. Controlled Formation and Characterization of Dithiothreitol-Conjugated Gold Nanoparticle Clusters
Topic: Nanobiotechnology
Published: 3/5/2014
Authors: De-Hao D. Tsai, Tae Joon Cho, Frank W DelRio, Justin M Gorham, Jiwen Zheng, Jiaojie Tan, Michael Russel Zachariah, Vincent A Hackley
Abstract: We report a systematic study of the controlled formation of discrete-size gold nanoparticle clusters (GNCs) by interaction with the reducing agent dithiothreitol (DTT). Asymmetric-flow field flow fractionation and electrospray differential mobility a ...

6. Disentangling the effects of polymer coatings on silver nanoparticle agglomeration, dissolution, and toxicity to determine mechanisms of nanotoxicity
Topic: Nanobiotechnology
Published: 9/1/2012
Authors: Justin M Zook, Melissa Danielle Halter, Danielle Cleveland, Stephen E Long
Abstract: Silver nanoparticles (AgNPs) are frequently coated by a variety of polymers, which may affect various intertwined mechanisms of toxicity, including agglomeration and dissolution rate. Here, we measure how citrate, dextran, poly(ethylene glycol) (PEG ...

7. Effects of temperature, acyl chain length, and flow-rate ratio on liposome formation and size in a microfluidic hydrodyanmic focusing device
Topic: Nanobiotechnology
Published: 3/21/2010
Authors: Justin M Zook, Wyatt N Vreeland
Abstract: Microfluidic hydrodynamic focusing of an alcohol/lipid mixture into a narrow fluid stream by two oblique buffer streams provides a controlled and reproducible method of forming phospholipid bilayer vesicles (i.e., liposomes) with relatively monodispe ...

8. 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 ...

9. 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 ...

10. 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 ...
