Summary
Osteoporosis affects 1.2 million Australians and will cost $33.6 billion by 2022. This study aims to develop a novel nano-cement platform for custom-designed bone repair in osteoporosis, by using purpose-designed nanomaterials and advanced 3D printing technique.

Meso- and Macro-porous Bioactive Glasses for Bone-repairing. This project aims to use self-assembly and pore engineering at different length scales to fabricate novel bioactive glasses of highly ordered mesoporous structure. By precisely controlling the composition, size and volume of both mesopores and macropores, bioactive glasses with improved bone forming activities will be obtained. The successful synthesis of such bioactive glasses is expected to lead to the fundamental understanding of st ....Meso- and Macro-porous Bioactive Glasses for Bone-repairing.

By precisely controlling the composition, size and volume of both mesopores and macropores, bioactive glasses with improved bone forming activities will be obtained. The successful synthesis of such bioactive glasses is expected to lead to the fundamental understanding of structure-bioactivity relationship, and new materials effective for tissue engineering. This will also open up new opportunities for other applications such as drug delivery, implanting.Read moreRead less
Convergence of biomaterials and immunology: a technology platform for delayed burst release of vaccines. A large challenge in vaccination, particularly in wildlife such as for the growing problem of Chlamydia in koalas, is to provide the necessary booster shots. This project will develop implants that will be inserted under the skin at the time of the first shot, and will spontaneously burst later to release the booster shot to provide protection.
Bioactive Polymers for Wound Healing Applications. VitroGroR is a growth factor complex which enhances cell growth and migration, and hence has great potential for treating wounds. Tissue Therapies, which holds the rights to commercialization of VitroGroR, is seeking to develop methods of delivering VitroGroR in its active form to the wound environment. Two solutions to this problem will be developed in this project; a bioactive bandage containing a novel combination of microspheres and a hydrog ....Bioactive Polymers for Wound Healing Applications.

Tissue Therapies, which holds the rights to commercialization of VitroGroR, is seeking to develop methods of delivering VitroGroR in its active form to the wound environment. Two solutions to this problem will be developed in this project; a bioactive bandage containing a novel combination of microspheres and a hydrogel matrix, and secondly an in-situ polymerisable matrix for treatment of deep wounds. The growth factor complex will be protected from aggressive proteases through encapsulation within microspheres, and the use of MMP-inhibiting comonomers.Read moreRead less
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

Murine polyomavirus (MPyV) capsid proteins self-assemble into spherical protein shells approximately 45 nm in diameter. Such virus-like particles (VLPs) are of considerable interest as bionanotechnological tools. The unique flexibility provided by MPyV VLPs will be exploited by exploring the ability of the interior cavity to retain bioactive cargos while engineering novel functionality on the exterior surface by 'mix-and-match' assembly of VLPs from modified components. As a proof of concept for next-generation vaccines that stimulate much needed, broadly protective responses against infectious diseases, model antigens will be delivered to specific immune cells using this nano-container.Read moreRead less

Tendons are important vertebrate tissues, but little is known about their mechanical properties under fatigue-loading. Recent research has shown that dramatic differences in fatigue properties occur and that these appear to be linked to the functional roles of tendons. This project uses a variety of approaches to explore how mechanical and structural properties of tendons change during growth, maturation and adaptation to different loading environments, and the cellular basis of fatigue resistance. An understanding of fatigue properties from cellular to tissue levels has significance in the areas of general biology, materials science and biomedical science.Read moreRead less
