Mapping Cell Distribution in Amorphous Scaffolds using Confocal Microscopy

August 19, 2007

Author(s)

Jirun Sun, Nancy Lin, Marcus T. Cicerone, Sheng Lin-Gibson

One common method for probing cell-material interactions is direct visualization via confocal laser scanning microscopy, a technique widely used for studying biological systems. However, confocal microscopy has limited depth penetration for imaging cells

Rapid Assessment of Dental Polymers Using Gradient Samples

April 18, 2007

Author(s)

Nancy J. Lin, Peter Drzal, Sheng Lin-Gibson

Dental composites are widely used yet still face challenges including incomplete conversion, polymerization shrinkage, and poor adhesion to tooth structures. High-throughput techniques to quickly assess several material properties in a combinatorial manner

Macrophage Response to Methacrylate Conversion Using a Gradient Approach

January 1, 2007

Author(s)

Nancy Lin, L A. Bailey, Matthew Becker, N. R. Washburn, Lori Henderson

Incomplete conversion, an ongoing challenge facing photopolymerized methacrylate-based polymers, affects leachables as well as the resulting network. As novel polymers and composites are developed, methods to efficiently screen cell response to these

Two Dimensional Gradient Platforms for Rapid Assessment of Dental Polymers: A Chemical, Mechanical and Biological Evaluation

November 14, 2006

Author(s)

Nancy Lin, Peter Drzal, Sheng Lin-Gibson

Objectives: The increased usage of composite dental restorations underscores the need for continued improvements in material properties. Well-controlled sample fabrication and reproducible methods to quantify and compare material properties will accelerate

High-Throughput Evaluation of Restorative Dental Polymers

March 31, 2006

Author(s)

Sheng Lin-Gibson, Forrest A. Landis, Nancy J. Lin

The effects of co-monomer composition and irradiation time on material properties and cell response were determined using high-throughput and combinatorial methods. 2-Dimensional gradient samples varying in monomer composition and light exposure time were

Combinatorial Methods to Access Cellular Response to Bis-GMA/TEGDMA Vinyl Conversion Levels

April 1, 2005

Author(s)

Nancy J. Lin, L A. Bailey, N Washburn

To facilitate the evaluation of dental composites, high throughput methods to fabricate dental resins with varying conversion levels were developed. Resins of 2,2-bis[4-(2-hydroxy-3-methacryloxypropoxy) phenyl]propane (Bis-GMA) and triethylene glycol
