Summary
Bone healing sites are commonly infected, and this is associated with adverse clinical and significant socioeconomic outcomes. These studies will determine whether our novel antimicrobials can be used to reduce bone infections by studying the combination of antimicrobials and bone in laboratory and bone fracture studies whilst minimising the potential of developing antibiotic resistance.
Bioactive And Biodegradable Scaffold And Novel Graft Source For The Repair Of Large Segmental Bone Defects

Funding Amount
$451,103.00
Summary
The treatment of large bone defects arising from trauma and tumour remains a challenge to orthopaedic surgeons. This project combines a well-established scaffold that can be custom-made to address patient specific requirements with a novel source of graft that can be harvested in significant volumes with minimal pain and morbidity. This novel tissue engineering approach will be evaluated in a previously established pre-clinical model that reflects the severity of challenging clinical scenarios.
Novel Biocompatible Nickel-free Shape Memory Alloy Scaffolds For Biomedical Applications

Funding Amount
$530,789.00
Summary
The current project is aimed at the development of a new class of novel biocompatible nickel-free shape memory alloy (SMA) scaffolds for metallic implant applications. The new scaffolds possess the ability to exert a mechanical force on the surrounding bones, and stimulate new bone tissue ingrowth, due to their shape memory effect, superelasticity and bone-mimicking porous structure. The outcomes from this project will provide innovative implant materials.
Bioengineering Synthetic Elastin Conduits For Arterial Revascularisation

Funding Amount
$624,776.00
Summary
An arterial substitute with both physical and biological properties that mimic those of the human vasculature has long been the holy grail of vascular tissue engineering. We propose synthetic elastin can form the basis of a durable, clinically effective small diameter vascular graft and fill a significant unmet need for a biocompatible vascular substitute.
Biocompatible Synthetic Conduits To Treat Vascular Disease

Summary
Clinically available synthetic conduits used in vascular repair and bypass are fundamentally incompatible with the vasculature. They cause inflammation at the site of implantation and increase the risk of blood clots forming. We have developed a unique method of binding bioactive protein layers to the surface of all polymeric materials and have shown a significant improvement in their compatibility. Grafts coated using our technology stand to dramatically improve the treatment of vascular diseas ....Clinically available synthetic conduits used in vascular repair and bypass are fundamentally incompatible with the vasculature.

Designing functional biomaterials with superior cellular interactions. This proposal aims to make a new class of biomaterials that direct important cellular functions such as adhesion, proliferation, and differentiation. This will be achieved by developing materials that leverage a previously unexplored mechanism that was recently identified in my lab: the co-engagement of integrin and syndecan-4 cell receptors. We will use these biomaterials to 1) fabricate 3D printed tissue engineering scaffo ....Designing functional biomaterials with superior cellular interactions.

Summary
There is a rapidly increasing and pressing medical need for the development of synthetic implants that can regenerate large amounts of lost or diseased bone. This project will produce a unique implant with optimal mechanical and biological performance, which represents a viable alternative to bone grafting with broad applications for the repair of large or challenging bone defects. Such an achievement will produce significant healthcare benefits and improved long-term outcomes.
Multiscale Study on Biomechanical Roles of Soft Tissue on Bone Remodelling. The project aims to increase our knowledge of the processes of bone remodelling and the role of soft tissue in this process. Mechanical force is a key stimulus for regulating bone remodelling. A significant question in biomechanics is why orthodontics only use very small forces (1 Newton) to generate significant oral bone remodelling, whereas prosthodontics that apply three orders of magnitude higher forces (~1000 Newton ....Multiscale Study on Biomechanical Roles of Soft Tissue on Bone Remodelling. The project aims to increase our knowledge of the processes of bone remodelling and the role of soft tissue in this process. Mechanical force is a key stimulus for regulating bone remodelling. A significant question in biomechanics is why orthodontics only use very small forces (1 Newton) to generate significant oral bone remodelling, whereas prosthodontics that apply three orders of magnitude higher forces (~1000 Newton) do not move dental implants. This project aims to develop new multiscale modelling and remodelling techniques in computational mechanics to explore the roles played by connective soft tissue in bone adaptation. Expected project outcomes would increase our understanding in biomechanics and affect health care disciplines such as orthodontics, prosthodontics and orthopaedics.Read moreRead less
