Biomolecular surface interactions with smart biomaterials. Current materials used for medical implants are often recognised by the body as foreign materials causing implant rejection or encapsulation. Research into the interactions between biological molecules and chemically and topographically modified materials will aid in the development of new materials and devices that optimise the body's response to the implanted material. The new materials and surfaces developed from this research will pr ....Biomolecular surface interactions with smart biomaterials. Current materials used for medical implants are often recognised by the body as foreign materials causing implant rejection or encapsulation. Research into the interactions between biological molecules and chemically and topographically modified materials will aid in the development of new materials and devices that optimise the body's response to the implanted material. The new materials and surfaces developed from this research will provide longer lasting implants and reduce the need for repeated operations. This will improve the quality of life for implant recipients and reduce health care costs.Read moreRead less
Design and Development of a Low-Cost Portable Biofeedback Device for use in Sleep Induction and Relaxation. This project aims to expand on existing knowledge of the various stimuli used in sleep induction such as photic, auditory and weak electromagnetic stimulation and develop a low-cost portable biofeedback prototype.

This novel device will be based on adaptive or fuzzy reasoning algorithms, which would be integrated into the existing ambulatory Siesta EEG recording system, produced by Compumedics Ltd. The development of this novel real-time biofeedback prototype will encourage further research using this particular technology to apply it in preventative healthcare in Australian community. The outcome of this proposed bioinstrumentation prototype could possibly expand sleep market to new international level.Read moreRead less
Injectable scaffolds for treatments of neurological disorders. Cell replacement therapies offer potentially effective treatments for a host of neurological disorders but a major obstacle confronting their development is to ensure appropriate connections are formed within the brain. This proposal aims to utilize injectable biodegradable polymers, to demonstrate the feasibility of assisting neural cells and stem cells to bridge glial scars or significant distances in the brain and repair damaged n ....Injectable scaffolds for treatments of neurological disorders. Cell replacement therapies offer potentially effective treatments for a host of neurological disorders but a major obstacle confronting their development is to ensure appropriate connections are formed within the brain. This proposal aims to utilize injectable biodegradable polymers, to demonstrate the feasibility of assisting neural cells and stem cells to bridge glial scars or significant distances in the brain and repair damaged neural pathways. This proposal will focus on naturally occurring polysaccharides, which will act as "scaffolds" for the growing neurones. The role the scaffolds play in regulating neurite extension will be investigated in vitro and in vivo.Read moreRead less
Manipulating nano-fibres to control nerve regeneration. Diseases of the brain and mind are the most common diseases in the western world; being even more prevalent than cardiac or malignant disease. With Australia's aging demographic, diseases of the brain and mind will continue to impact on our productivity in the workplace, our quality of life, and the ability of the medicare and private health care systems to keep up with the ever-increasing demand for older Australians.

This project addresses the National Research Priority of Promoting and Maintaining Good Health and specifically the Priority Goal of Ageing well, ageing productively. Osteoarthritis, the most common cartilage-related disease, affects nearly 1.4 million Australians, resulting in 2 in 1000 Australians undergoing total joint replacement, annually. The incidence and impact of cartilage damage on the Australian health and economy is expected to increase with the ageing population. This work leads to the development of a novel cartilage engineering technology platform that addresses Frontier Technologies and will thus provide the foundation for translation of this technology to the international marketplace.

This proposal aims to design a new bio-adhesive material and study the mechanisms of action for tissue adhesion. Current suture technology is inadequate for anything but simple repairs and the alternative offered by surgical glues available today is at most augmentation of suturing. Combination of a strong adhesive biomaterial with factors for accelerating wound healing will generate a novel material technology that, by uniting wound closure with sealing, addresses an unmet need in surgery.
The primary outcomes of these investigations will be:
1. advancement of knowledge in theories of tissue-biomaterial adhesion mechanisms
2. knowledge of effects of visible light from laser diodes on cells and isolated tissue
3. a biocompatible, visible light activated adhesive film for tissue repair based on chitosan polysaccharides
