Biomedical implants are increasingly being used for the treatment of a variety of ailments. This project will significantly contribute to the development of these bioengineered constructs, by introducing an innovative method for tailoring the nature of the surface of these materials with structures that mimic the response of biological surfaces. This technology has the potential to promote favourable interactions of cells with biomedical implants, and an initial targeted application will be to use these bioengineered constructs in the treatment of preventable blindness and severe visual impairment, afflictions which affect over 180 million individuals worldwide.Read moreRead less

Calcification of acrylic hydrogels in abiotic media: mechanism and control. Poly(2-hydroxyethyl methacrylate (PHEMA) and other acrylic hydrogels are extensively used as biomaterials, yet conclusive evidence exists that they have a propensity to calcify following implantation. This process has undesirable consequences on the functionality of various prostheses. Based on preliminary observations that PHEMA can promote the deposition of calcium minerals from media devoid of biological factors, whic ....Calcification of acrylic hydrogels in abiotic media: mechanism and control. Poly(2-hydroxyethyl methacrylate (PHEMA) and other acrylic hydrogels are extensively used as biomaterials, yet conclusive evidence exists that they have a propensity to calcify following implantation. This process has undesirable consequences on the functionality of various prostheses. Based on preliminary observations that PHEMA can promote the deposition of calcium minerals from media devoid of biological factors, which appears thus to be an inherent property of the polymer, the project aims at formulating new hypotheses to explain this phenomenon, and to confirm them experimentally. The "chelation" hypothesis will be validated by modifying the structure of polymers, and the "spontaneous precipitation" hypothesis by assessing the effect of solutes on the equilibrium water content of polymers. NMR and FTIR spectrometric techniques will be used to gain further insight into the mechanism of calcification. Methods to prevent the calcification will potentially result from these experiments, however, anticalcification agents will also be incorporated into hydrogels and their effect evaluated in calcification assays.Read moreRead less
Biodegradable Porous HEMA-Based Polymers: Innovative Strategies for the Design and Tuneable Single-Step Production of a Novel Class of Scaffolds for Tissue Engineering. This project will lead to the development of new biocompatible, biodegradable, porous materials ideally suited to many applications in tissue engineering.

This project will lead to the development of new biocompatible, biodegradable, porous materials ideally suited to many applications in tissue engineering. These new biomaterials will be relatively inexpensive to manufacture, via simple processes using non-toxic reagents. The key properties of the biomaterials will be controllable by appropriate choice of starting materials. The availability of these new biomaterials will facilitate future developments in tissue engineering, which will ultimately lead to improved medical outcomes in areas as diverse as joint and bone repair and organ regeneration. Local manufacture of these biomaterials would also contribute to the development of the Australian biotechnology industry.Read moreRead less
