Hermetic bonding of biomedical polymers for cardiac-assist devices. The use of a polymeric ventricular assist device will bring a much better quality of life to patients with end-stage heart failure. The project will address the remaining challenge, the creation of a hermetic polymer seal, enabling the development of a small, light and highly efficient heart pump. The project has the potential to improve the lives of many Australians as our demographic profile shifts towards older people.

The use of a polymeric ventricular assist device will bring a much better quality of life to patients with end-stage heart failure. The project will address the remaining challenge, the creation of a hermetic polymer seal, enabling the development of a small, light and highly efficient heart pump. The project has the potential to improve the lives of many Australians as our demographic profile shifts towards older people. Patients with advanced heart failure will live longer, with a higher quality of life. It will assist heart failure sufferers to remain productive members of our community, because many people who use the device will be fit to return to work.Read moreRead less
Synthesis of Novel Biomaterials for Drug delivery. A new UV radiation polymerisation technique utilising charge-transfer complexes is adopted for synthesising novel hydrogels, a group of biomaterials for drug delivery. This work is significant as charge-transfer complexes, pertinent to the formation of hydrogels, form copolymers within the hydrogel matrices. This eliminates using costly, yet undesirable photo-initiators (PI), thus rendering the hydrogels as cleaner (PI-free) and more economical ....Synthesis of Novel Biomaterials for Drug delivery. A new UV radiation polymerisation technique utilising charge-transfer complexes is adopted for synthesising novel hydrogels, a group of biomaterials for drug delivery. This work is significant as charge-transfer complexes, pertinent to the formation of hydrogels, form copolymers within the hydrogel matrices. This eliminates using costly, yet undesirable photo-initiators (PI), thus rendering the hydrogels as cleaner (PI-free) and more economical in production; the products present themselves as ideal treatment methods in the controlled-release of drugs, specifically targeting localised pathological sites of interest. The research findings will be invaluable to medical practices, leading to the creation of new industries in Australia.

Development and characterisation of novel hydrogel systems for drug delivery. The aims of this project are to develop and characterise hydrogel formulations for delivery of active agents, such as protein drugs, and to examine the biological responses to drug loaded hydrogels. In many medical and industrial fields, it is advantageous to control the release of active agents. Controlled release can decrease the dose of active that must be administered, sustain a more constant level of the agent ....Development and characterisation of novel hydrogel systems for drug delivery. The aims of this project are to develop and characterise hydrogel formulations for delivery of active agents, such as protein drugs, and to examine the biological responses to drug loaded hydrogels. In many medical and industrial fields, it is advantageous to control the release of active agents. Controlled release can decrease the dose of active that must be administered, sustain a more constant level of the agent in the environment and can localise the agent at the site where it is needed. This project will advance the theoretical knowledge of polymer degradation combined with protein release, will develop controlled release hydrogel technology that can be applied to medical devices and will train a postgraduate student in biomaterials and drug delivery.Read moreRead less
Nanoporous siloxane membranes for ultrasound mediated ophthalmic drug delivery. This project will develop tailored polymers for use in a novel non-invasive ocular drug delivery device which treats vision threatening conditions such as age-related macular degeneration (AMD). The outcomes of this project will enable an entirely new ocular drug delivery technology, thereby delivering significant benefit to ophthalmic healthcare.
NOVEL TRI-BLOCK CO-POLYMERS FOR CONTROLED RELEASE OF PROTEINS FOR OSTEOGENESIS. This research is being driven by the need for a scaffold for orthopaedic reconstruction that provides controlled release of growth factors to enable rapid healing. None of the current systems possess the required combination of properties to enable new tissue to regenerate rapidly. The aim of this project is to design a system for sustained drug release using block copolymer micelles to encapsulate growth factors and ....NOVEL TRI-BLOCK CO-POLYMERS FOR CONTROLED RELEASE OF PROTEINS FOR OSTEOGENESIS. This research is being driven by the need for a scaffold for orthopaedic reconstruction that provides controlled release of growth factors to enable rapid healing. None of the current systems possess the required combination of properties to enable new tissue to regenerate rapidly. The aim of this project is to design a system for sustained drug release using block copolymer micelles to encapsulate growth factors and then polymerising the micelles in a biodegradable polymer scaffold. This would enable local delivery of osteogenic growth factors to a bone defect.Read moreRead less
Plasma processes for optimising the performance of surfaces for biomedical applications. Australia faces a number of pressing problems in health care, including an aging population, environmental damage control and national security, which can be addressed, in part, by effectively interface synthetic materials surfaces with biological systems. Examples of technologies relying on such functional interfaces include implantable medical devices and prostheses, enzymatic conversion of chemicals and w ....Plasma processes for optimising the performance of surfaces for biomedical applications. Australia faces a number of pressing problems in health care, including an aging population, environmental damage control and national security, which can be addressed, in part, by effectively interface synthetic materials surfaces with biological systems. Examples of technologies relying on such functional interfaces include implantable medical devices and prostheses, enzymatic conversion of chemicals and waste, as well as diagnostic arrays and biosensors. The new understanding of fundamental surface properties driving these interactions, together with the new surface modification processes developed in this project, will drive new technologies in these important areas.Read moreRead less
