| Summary: | With increasing demand of engineered tissues, natural polymers are promising alternative to conventional synthetic scaffolding materials in terms of biocompatibility and overall interactions with cells. An example of a natural polymer is ovalbumin (OVA), which has yet to be intensively researched to evaluate its potential for tissue engineering applications.
In this project, the effect of fabrication method and cross-linker concentration on ovalbumin scaffold properties was investigated. Glutaraldehyde (GA) was used to cross-link OVA; and two fabrication techniques, salt-leaching and freeze-drying, were used to fabricate OVA scaffolds. In addition, purification of OVA from chicken egg white was performed to investigate the feasibility of separating OVA from a simple ultrafiltration scheme. |
