Surface engineering of biomaterials for optimal bone bonding characteristics. The ideal bone-implant material is hydroxyapatite. Chemically similar to bone mineral, hydroxyapatite is capable of inducing bone ongrowth. An ideal surface coating for metal hip implants, plasma spraying has been the preferred commercial hydroxyapatite coating technique. Until recently, it was always presumed that the bioactivity of hydroxyapatite resulted from its surface chemistry. However, a recent study has shown ....Surface engineering of biomaterials for optimal bone bonding characteristics. The ideal bone-implant material is hydroxyapatite.

An ideal surface coating for metal hip implants, plasma spraying has been the preferred commercial hydroxyapatite coating technique. Until recently, it was always presumed that the bioactivity of hydroxyapatite resulted from its surface chemistry. However, a recent study has shown that the bioactivity of HAp coatings strongly correlates with surface roughness on the scale of bone cells. This project will explore cell-attachment behaviour for hydroxyapatite coatings prepared by plasma spraying compared with engineered surface morphology/chemistry by microlithography and vapour coating.Read moreRead less
Numerical investigation of signal mechanotransduction of bone cells - application to bone remodeling. The understanding of signal mechanotransduction of bone cells is directly related to mechanical activation of bone remodeling processes, i.e., resorption and formation of bone tissue. Understanding of bone remodeling is essential for the development of new bone implants, the prognosis of osteosporosis, and studies related to changes in microgravity (e.g. space flight) to name a few key applicati ....Numerical investigation of signal mechanotransduction of bone cells - application to bone remodeling.

Glaucoma is a leading cause of preventable blindness, particularly prevalent in the 60+ population, caused by elevated intraocular pressure (IOP). Current treatment to monitor and prevent glaucoma-related blindness is by lowering IOP with eye-drops, laser therapy or surgery. This project directly benefits our aging population by ensuring independence and quality of life, whilst reducing long-term medical and social costs. By incorporating nanotechnology with ophthalmology we will provide an economic solution to long-term, reliable, home-monitoring of IOP. An implantable IOP sensor, will identify patients requiring more invasive treatment compared with those with less aggressive disease, leading to better health resource utilisation.Read moreRead less

Summary
A Multi-Axis Biomaterials Testing Facility. Damage to bones and joints, due to injury or diseases such as osteoporosis and arthritis, is a major cause of disability and cost to the nation. Australia's ageing population contributes not only to an increasing incidence of such conditions, but also to more patients out-living implants such as replacement joints. In 2001-2, Australia spent over $800 million on joint replacement. Because over 11% of procedures are revisions of failed implants, even sm ....A Multi-Axis Biomaterials Testing Facility. Damage to bones and joints, due to injury or diseases such as osteoporosis and arthritis, is a major cause of disability and cost to the nation. Australia's ageing population contributes not only to an increasing incidence of such conditions, but also to more patients out-living implants such as replacement joints. In 2001-2, Australia spent over $800 million on joint replacement. Because over 11% of procedures are revisions of failed implants, even small improvements in implant life represent significant cost savings. By accurately simulating conditions within the body, this biomechanical testing facility will lead to new developments in implant designs and materials, in turn improving quality of life, productivity and treatment costs.Read moreRead less
Bone regulation - cell interactions to disease. Many bone disorders such as osteoporosis, Paget's disease and chancer related bone diseases are directly related to disruption of communication pathways between bone cells leading to imbalances in bone remodeling. Although these disorders are common and cause considerable suffering, in most cases little is known about the mechanisms responsible for dysfunctional remodeling. Understanding the communication network between bone cells and their inter ....Bone regulation - cell interactions to disease. Many bone disorders such as osteoporosis, Paget's disease and chancer related bone diseases are directly related to disruption of communication pathways between bone cells leading to imbalances in bone remodeling. Although these disorders are common and cause considerable suffering, in most cases little is known about the mechanisms responsible for dysfunctional remodeling. Understanding the communication network between bone cells and their interaction with drugs is essential in order to develop new therapies and to effectively design novel biological compatible bone implants. This research proposal closely aligns with national research priority two, i.e., promoting and maintaining good health (ageing well, ageing productively).Read moreRead less
Using nanostructured biomaterials and stem cells to repair spinal cord injuries. There is currently no effective cure for spinal cord injuries and the consequences to the patient are devastating. Spinal cord injuries affects limb, bowel, bladder and sexual function, and many people with these injuries strugle to maintain their independence.

There is currently no effective cure for spinal cord injuries and the consequences to the patient are devastating. Spinal cord injuries affects limb, bowel, bladder and sexual function, and many people with these injuries strugle to maintain their independence. Because people can live for many years after spinal cord damage, the financial and social costs are immense, as many are dependent on the help of others for their survival. This proposal tackles this urgent problem by applying advanced nanostructured materials with stem cells, to assist the body in the repair of the spinal cord following injury. Read moreRead less
