Assessing Viscoelastic Properties of Chitosan Scaffolds and Validating Sequential and Cyclical Tests
(Oklahoma State University, 2011-12-01)We evaluated and modeled the viscoelastic characteristics of chitosan and chitosan gelatin scaffolds prepared using a freeze-drying technique. Chitosan and chitosan-gelatin solutions (0.5 wt% and 2 wt%) were frozen at -80�C ... -
Effects of Chitosan-Gelatin Hydrogels on Fibro-Chondrogenesis
(Oklahoma State University, 2011-12-01)The objective of this study was to investigate a hydrogel system that is easy to utilize in the clinical settings to produce cartilage and an autologous cell source for chondrocytes such as easily available human foreskin ... -
Emulsified Chitosan-plga Scaffolds for Tissue Engineering
(Oklahoma State University, 2005-12-01)This study evaluated the formation of chitosan-50:50 poly-lactic-co-glycolic acid (PLGA) blend matrices using controlled rate freezing and lyophilization technique. An emulsion system was used in the presence of ... -
Mass transfer in porous tissue engineering scaffolds
(2008-07)Scope and Method of Study: This study evaluated the effects of both local and global scale mass transport phenomena through degradable porous polymer matrices typically used in tissue engineering. Analytical, computational ... -
Polycaprolactone Matrices Generated in Aqueous Media: Natural Polymers Immobilization and Stress Relaxation Behavior
(Oklahoma State University, 2010-05-01)This study determined the possibility of immobilizing natural polymers onto self-assembled polycaprolactone (PCL) matrices and its effect on tensile properties of the PCL matrix. The stress relaxation behavior of self-assembled ... -
Spatial Distribution of Cells Within Void Volume of a Chitosan-collagen Scaffold
(Oklahoma State University, 2012-07-01)In tissue engineering, cells must be uniformly distributed within 3D scaffolds in order to receive adequate nutrition and oxygen. The objective of this project is to test a novel method to seed cells within a three-dimensional ...
