By developing new methodologies for producing functional biomaterials, this research will benefit Australia by continuing our high profile in this research field and by producing economic benefits arising from development and export of materials technologies to the major user groups in USA and Europe. With our demonstrated linkages with Australian based biomaterials developers at CSIRO and University of Queensland, as well as with companies involved in the commercialisation of polyurethane based medical devices (Aortech P/L), this group is well placed to continue the research at a more applied level once the early basic stage is complete.Read moreRead less
Non-invasive control of an implantable rotary blood pump used as a left ventricular assist device. The Holy Grail for developers of rotary blood pumps used as left ventricular assist devices is to control the pump to meet the body's metabolic demand and to do this without the need for implanting additional sensors. The controller must also detect and avoid dangerous states associated with over and under pumping.
In this research we will derive and implement a pump control algorithm that will ....Non-invasive control of an implantable rotary blood pump used as a left ventricular assist device.

The controller must also detect and avoid dangerous states associated with over and under pumping.
In this research we will derive and implement a pump control algorithm that will allow non-invasive prediction of pump flow, automatic detection of pumping states and adjustments for the metabolic demand of the body. The algorithms will be tested on the bench and in animal and human studies.Read moreRead less
Understanding glycopolymer interactions with the extracellular matrix. This project aims to advance knowledge of the biochemical and biophysical structure of the endothelial glycocalyx, a dynamic cell surface extracellular matrix rich in proteoglycans and glycosaminoglycans. It will be the first to explore how charged glycopolymers interact with this dynamic interface with the goal to develop a model of the glycocalyx lifecycle.

Novel Antimicrobial Biomaterials. There is a clear need for new materials that repel bacteria. Infections associated with biomaterials incur a high cost in terms of human health and well being, but such infections also increase the burden on the health care system by extending hospital stays and significantly elevating costs. The cost of a catheter-related blood stream infection is around $50,000 for patients in intensive care units. If all medical devices are considered, the cost of related inf ....Novel Antimicrobial Biomaterials. There is a clear need for new materials that repel bacteria. Infections associated with biomaterials incur a high cost in terms of human health and well being, but such infections also increase the burden on the health care system by extending hospital stays and significantly elevating costs. The cost of a catheter-related blood stream infection is around $50,000 for patients in intensive care units. If all medical devices are considered, the cost of related infections is then approximately $20 billion. The technology proposed here has the potential to reduce biomaterial related infection rates, improve health care and reduce health care costs. Read moreRead less
