Interfacial interactions with hydrogel biomaterials. The interactions between cells of the body and the surfaces of medical implants are controlled largely by the molecules that are adsorbed on the surface. The aim of this project is to evaluate the effect of modifying hydrogel biomaterials on the interactions of the molecules with the hydrogel. This, in turn, allows us to determine the factors affecting the control of the cell's response. The significance of this work is in the improved ability ....Interfacial interactions with hydrogel biomaterials.

The aim of this project is to evaluate the effect of modifying hydrogel biomaterials on the interactions of the molecules with the hydrogel. This, in turn, allows us to determine the factors affecting the control of the cell's response. The significance of this work is in the improved ability to control cellular responses to implants. Such improved response will result in better health outcomes for patients, and outcomes in the form of papers and intellectual property.

Novel coding and decoding in suspension arrays for accelerated biomolecular discovery and personalised medicine. This project will establish an advanced multiplexing technique to rapidly analyse complex biological mixtures, such as cell lysates, food samples or body fluids. It will enable the analysis of not tens, but thousands or more distinctive molecular targets in a single test. This will build the foundations for future generation bioassays, paving the way to emerging personalised medicine. ....Novel coding and decoding in suspension arrays for accelerated biomolecular discovery and personalised medicine.

Improving orthopaedic/dental devices by surface chemical modification. The estimated world market for the orthopaedic implants is expected to be US$125 billion by 2010. Australia imports most of it's orthopaedic implants with an estimated cost in excess of AUD300 million by 2010. The current rate of prosthetic failures in orthopaedic patients is unacceptably high. The project aims to develop new implants that integrate better into bone, thus reducing the rate of revision arthroplasty.

Australia imports most of it's orthopaedic implants with an estimated cost in excess of AUD300 million by 2010. The current rate of prosthetic failures in orthopaedic patients is unacceptably high. The project aims to develop new implants that integrate better into bone, thus reducing the rate of revision arthroplasty. This would lead to a significant reduction in the cost of health care in our aging population and improve the quality of life for prosthetic recipients.
