1. Adsorption Behavior of DNA-Wrapped Carbon Nanotubes on Self-Assembled Monolayer Surfaces
Topic: Biomaterials
Published: 5/22/2007
Authors: Rebecca A Zangmeister, James E Maslar, A Opdahl, Michael J Tarlov
Abstract: We have examined the adsorption of DNA-wrapped single walled carbon nanotubes (DNA-SWNTs) on hydrophobic, hydrophilic, and charged surfaces of alkylthiol self-assembled monolayers (SAMs) on gold. Our goal is to understand how DNA-wrapped SWNTs intera ...

3. Combinatorial Screening of Hydrogels for 3-D Cell Culture: Osteoblasts in Stiffness Gradients Yield Graded Tissues
Topic: Biomaterials
Published: 7/1/2010
Authors: Kaushik Chatterjee, Sheng Lin-Gibson, William E Wallace III, Marian F Young, Carl GEORGE Simon Jr
Abstract: A combinatorial library approach was used to demonstrate that hydrogel scaffold modulus can enhance osteoblast differentiation driving formation of a 3-D graded tissue construct. Though many previous studies have focused on screening cell-material i ...

4. Combinatorial Screening of Osteoblast Response to 3D Nano-Composite Tissue Scaffolds Using Gradients and Arrays
Topic: Biomaterials
Published: 4/24/2011
Authors: Carl GEORGE Simon Jr, Kaushik Chatterjee, Limin Sun, Laurence Chung Lung Chow, Marian F Young
Abstract: Current methods for combinatorial and high-throughput (CHT) screening of cell-material interactions utilize a two-dimensional (2D) format where cells are presented on flat materials surfaces [1]. However, cell response in 3D scaffolds is more represe ...

5. DNA Hydrogel Plugs Immobilized in Microfluidic Channels with Improved Stability
Topic: Biomaterials
Published: 2/28/2002
Authors: Rebecca A Zangmeister, K G Olsen, David J Ross, Michael J Tarlov
Abstract: It has been previously demonstrated that DNA, modified on the 5' end with an acrylic acid group, can be incorporated into a polyacrylamide hydrogel matrix. These types of DNA containing gels have recently been immobilized in plastic microfluidic cha ...

6. Diffusion of Ions between Two Solutions Saturated With Respect to Hydroxyapatite: A Mechanism for Subsurface Demineralization of Teeth
Series: Journal of Research (NIST JRES)
Topic: Biomaterials
Published: 7/17/2010
Author: Laurence Chung Lung Chow
Abstract: Diffusion-controlled dissolution and precipitation reactions occur in many biological systems and some non-stirred in vitro systems. Previous studies have shown that differences in the diffusion rates of ions involved in a dissolution/precipitation ...

7. Effect of 3D Hydogel Scaffold Modulus and Topology on Human Bone Marrow Stromal Cell Fate
Topic: Biomaterials
Published: 9/1/2010
Authors: Kaushik Chatterjee, Sheng Lin-Gibson, Sapun Parekh, Nicole M. Moore, Marcus T Cicerone, marian f young, Carl GEORGE Simon Jr
Abstract: There is growing recognition that cells can sense and respond to the physical cues from their environment, such as stiffness, mechanical loading and topology. Physical properties of the matrix can direct cellular response and are critical in the desi ...

8. Effect of 3D Hydrogel Scaffold Stiffness on Human Bone Marrow Stromal Cell Differentiation
Topic: Biomaterials
Published: 11/1/2010
Authors: Carl GEORGE Simon Jr, Sapun Parekh, Marcus T Cicerone, Sheng Lin-Gibson, Kaushik Chatterjee, Marian F Young
Abstract: There is growing recognition cells can sense and respond to the mechanical properties of tissue scaffolds and that these interactions are critical in optimizing scaffold design [1-4]. Previous studies in planar 2D culture format have shown that human ...

9. Effect of 3D Scaffold Structure on Osteogenic Differentiation of Human Bone Marrow Stromal Cells
Topic: Biomaterials
Published: 4/24/2011
Authors: Carl GEORGE Simon Jr, Girish Kumar, Marian F Young
Abstract: Structural properties of polymeric scaffolds for tissue engineering play a key role in directing osteogenesis. These properties depend on the chemical nature and the fabrication process of biomaterial. There are many protocols for fabricating scaff ...

10. Effects of sample preparation on bacterial colonization of polymers
Topic: Biomaterials
Published: 10/19/2009
Authors: Diana N. Zeiger, Christopher M Stafford, Yajun Cheng, Stefan D Leigh, Sheng Lin-Gibson, Nancy J Lin
Abstract: Characterization of materials developed for medical usage frequently includes studies in which the materials are inoculated with bacteria in order to assess biofilm formation. Differences in the bacteria are considered to be due to the material alon ...
