Development of a Prothrombogenic Bone Graft Substitute. The clinical demand for bone is massive and to counter this bone can be either harvested from the patient or bone substitutes are used. The success or failure of a bone substitute is determined the instant it come into contact with blood. The surfaces of traditional biomaterials induce a foreign body reaction. The aim of this project is to test the bone forming capacity of a biomaterial that is optimised to produce a natural response from ....Development of a Prothrombogenic Bone Graft Substitute. The clinical demand for bone is massive and to counter this bone can be either harvested from the patient or bone substitutes are used. The success or failure of a bone substitute is determined the instant it come into contact with blood. The surfaces of traditional biomaterials induce a foreign body reaction. The aim of this project is to test the bone forming capacity of a biomaterial that is optimised to produce a natural response from the blood. This response will lead to the formation new viable tissue and eventually bone. Such a material will cause faster bone healing, less pain from graft sites, shorter hospital stays and shorter waiting lists. Read moreRead less

The aim of this research is to provide a simple method for creating complex 3D cell cultures for in vitro cell based assays using 3D printing. A versatile polymer system as a bioink made from entirely commercially available components, will be advanced that gives a full range of soft tissue mimics and which can be dynamically change on-demand after printing of the 3D cell cultures. The latter will provide in vitro mimics of in vivo events never previously possible with more realistic models of what is found in vivo. Applications are in fundamental cell biology, studying diseases and developing new drugs. The outcomes from this research will be new knowledge on designing cheap extracellular matrix mimics and high throughout 3D cell assays.Read moreRead less

2. To determine the mechanical properties of remineralised tissue and compare with those of sound enamel.
3. To develop an in-vivo optical fibre probe for monitoring and quantifying the changes of mineralised carious tissue during remineralisation.
This project will enable patients prone to orthodontic induced root resorption to be identified and also to assist with validating repair of enamel tooth structure in a non-surgical manner. It is anticipated to result in the development of a novel fibre optic instrument with applications beyond dentistry.

These highly innovative devices and the materials that they are made from have enormous commercial potential in biomedical engineering. There is a strong potential for Australia to have an important stake in this area by combining expertise in engineering, chemistry and nanostructured materials.Read moreRead less
Rapid Development of Biocompatible Stent Grafts for Aortic Aneurysms. Weakening of the aorta may cause an aneurysm. The present technique of its treatment involves replacing the weakened portion of the aorta with a synthetic graft. Failure of this treatment often occurs due to non-compatibility of the stent graft with natural aorta. One possible reason for this is a mismatch between elastic natural aorta and the non-elastic artificial graft. The core component of our project is the selection and ....Rapid Development of Biocompatible Stent Grafts for Aortic Aneurysms. Weakening of the aorta may cause an aneurysm. The present technique of its treatment involves replacing the weakened portion of the aorta with a synthetic graft. Failure of this treatment often occurs due to non-compatibility of the stent graft with natural aorta. One possible reason for this is a mismatch between elastic natural aorta and the non-elastic artificial graft. The core component of our project is the selection and development of a suitable biomaterial and optimization of the stent design based on hemodynamics flow analysis and its fabrication with the Fused Deposition Modelling (FDM) process.Read moreRead less
In Vitro Study of Hemodynamic Stresses and Endothelialization of Artificial Coronary Arteries. Restenosis (recurrence of the disease) is a major problem in the case of patients undergoing artificial artery by-pass surgery. Ideally the design for manufacturing the scaffold for cell adhesion of the artery should factor in hemodynamic forces and optimised geometry to withstand the hemodynamic stresses and other forces.

Restenosis (recurrence of the disease) is a major problem in the case of patients undergoing artificial artery by-pass surgery. Ideally the design for manufacturing the scaffold for cell adhesion of the artery should factor in hemodynamic forces and optimised geometry to withstand the hemodynamic stresses and other forces. This project aims to investigate the material for manufacturing the artificial artery using Fused Deposition Modeling and to develop methods for the establishment of endothelium on the artificial artery, concluding a restenosis-free solution for by-pass surgery. The knowledge gained through this work would be applicable to the design of other prosthetic devices.Read moreRead less
