Electric field induced surface attachment and detachment of proteins. Microarrays are revolutionising the diagnosis of disease by enabling large amounts of data on genetics and protein expression to be obtained from one sample. Biosensors for diseases and toxins rely on the same mechanism, namely attachment of biological macromolecules to a surface. We propose a new method for controlling the attachment by micromachining an electrode system to apply an electric field to chosen sites. Ultimately ....Electric field induced surface attachment and detachment of proteins. Microarrays are revolutionising the diagnosis of disease by enabling large amounts of data on genetics and protein expression to be obtained from one sample. Biosensors for diseases and toxins rely on the same mechanism, namely attachment of biological macromolecules to a surface. We propose a new method for controlling the attachment by micromachining an electrode system to apply an electric field to chosen sites. Ultimately microelectronic engineering methods will be used. This will give control over the attachment process with potential benefits of orienting attaching molecules, minimising non-specific attachment and enriching diagnostics by enabling interrogation of the force of attachment.Read moreRead less

This project aims to design and engineer photocatalytic ceria of systematically controlled grain sizes and morphologies, using doping methods to achieve pure and mixed quantum confinement (which enhances performance). The intended outcomes of the computation, fabrication, and validation approach are a fundamental knowledge of the processing-performance matrix and reproducible photocatalysts of optimised performance. While these ceramics will be applied as bioceramics, which can be activated by ultraviolet light, X-rays and ultrasound, the benefits will be applicable in energy (solar cells, photoelectrodes) and the environment (air and water purification).Read moreRead less

A successful outcome for this project would lead to the production and application of new bone-like calcium phosphate materials. Enhanced bioactivity of this material would lead to higher but controlled rates of calcium phosphate release. An understanding of the formation process of these materials and the controlled release of calcium phosphates has the potential to slow the development of metabolic diseases such as osteoporosis. The WHO reports that osteoporosis is the second largest health care problem world-wide. In 2002, 44 million people in the USA were estimated to be at risk. This and similar figures in Australia and around the world emphasize the urgency of understanding and appropriately combating weak bone degenerative diseases.Read moreRead less

Using dewetting of thin polymer films, the present proposal will develop new structured biocompatible surfaces with controlled chemistry and topography, which will allow the growth of a normal (non-activated) monolayer of endothelial cells. Sophisticated molecular parameters will be used to assess that endothelial cells maintain their normal quiescent phenotype. The project sets the ground work for the design of improved, more biocompatible structured stents to minimise the abnormal growth of cells on and around the stent, thereby reducing the occurrence of vascular complications. Thus this research could improve the success rate of stents implanted into patients with cardiovascular disease and reduce health costs.Read moreRead less
