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

Encapsulated Chondrocyte Response to Pulsatile Flow Bioreactor

August 16, 2006
Author(s)
James A. Cooper, W Li, L A. Bailey, Steven D. Hudson, Sheng Lin-Gibson, Kristi S. Anseth, Rocky Tuan, N Washburn
We have developed a bioreactor using microfluidic techniques that allow for dynamic culture conditions and measurement of the fluid flow impinging upon a three-dimensional (3-D) tissue engineering (TE) scaffold. Chondrocytes in scaffolds have been shown to

Combinatorial Method for Determining Optimum Tissue Scaffold Composition for Imaging by X-Ray Techniques

April 12, 2006
Author(s)
Carl G. Simon Jr., Yanyin Yang, Shauna M. Dorsey, Gary E. Schumacher, Glenn M. Flaim, J Kohn, Sheng Lin-Gibson, Matthew Becker
X-ray imaging techniques can be very useful for tissue engineering applications. The ability to image radiopaque medical implants in vivo with X-ray radiography enables clinicians to conveniently, inexpensively and non-invasively monitor wound healing and

Measuring the Modulus of Soft Polymer Networks via a Buckling-Based Metrology

April 1, 2006
Author(s)
Elizabeth A. Wilder, Shu Guo, Sheng Lin-Gibson, Michael J. Fasolka, Christopher Stafford
We present a new method for measuring the modulus of soft polymer networks (E 10 MPa).This metrology utilizes compression-induced buckling of a sensor film applied to the surface of the specimen,where the periodic buckling wavelength, assessed rapidly by

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
