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

ARC Research Hub for Integrated Device for End-user Analysis at Low-levels. This hub aims to improve detection of biological materials by building a portable device for rapid, time-critical detection of low-abundance molecular and cellular analytes. It is expected that the resulting technologies would be used at medical points of care, ordinary workplaces and centres of activity to test for tiny levels of targeted molecules. The initial focus would be early diagnosis of disease and point-of-care drug testing for humans and animals, but the technology platform could be used to sample food and environmental toxins. The hub expects these disruptive technologies will make Australian biotechnology, diagnostics, veterinary, agribusiness and manufacturing firms globally competitive.Read moreRead less
Targeted crime: policing and social inclusion. This project will undertake a criminological study of the policing of targeted incidents and crime, that is, incidents and crimes motivated by bias, prejudice or hatred towards members of particular groups, communities and individuals. It will develop a best practice policing framework for targeted crimes and incidents.
Development of a Prothrombogenic Bone Graft Substitute. The clinical demand for bone is massive and to counter this bone can be either harvested from the patient or bone substitutes are used. The success or failure of a bone substitute is determined the instant it come into contact with blood. The surfaces of traditional biomaterials induce a foreign body reaction. The aim of this project is to test the bone forming capacity of a biomaterial that is optimised to produce a natural response from ....Development of a Prothrombogenic Bone Graft Substitute. The clinical demand for bone is massive and to counter this bone can be either harvested from the patient or bone substitutes are used. The success or failure of a bone substitute is determined the instant it come into contact with blood. The surfaces of traditional biomaterials induce a foreign body reaction. The aim of this project is to test the bone forming capacity of a biomaterial that is optimised to produce a natural response from the blood. This response will lead to the formation new viable tissue and eventually bone. Such a material will cause faster bone healing, less pain from graft sites, shorter hospital stays and shorter waiting lists. Read moreRead less

Improving diagnostic accuracy and treatment options for equine PPID. Equine Pituitary Pars Intermedia Dysfunction (PPID) is a common, chronic and potentially life-threatening disease of older horses and ponies. Although a treatment is available, the disease is poorly understood and there are some concerns that the current diagnostic technology is not delivering accurate results. Thus, this project aims to develop a more accurate diagnostic test for PPID, while exploring the relationship between ....Improving diagnostic accuracy and treatment options for equine PPID. Equine Pituitary Pars Intermedia Dysfunction (PPID) is a common, chronic and potentially life-threatening disease of older horses and ponies. Although a treatment is available, the disease is poorly understood and there are some concerns that the current diagnostic technology is not delivering accurate results. Thus, this project aims to develop a more accurate diagnostic test for PPID, while exploring the relationship between PPID and metabolic syndrome, to generate new insights into the cause and consequences of both diseases. As an added benefit, the project will assist horseracing laboratories to improve their detection methods for peptide doping in younger competition horses.

While sutures currently represent the gold standard for wound closure, their fundamental technology has changed little in thousands of years. Surgical sealants and energy based closure devices are expected to increasingly replace or complement sutures, improving tissue closure and wound healing. The innovative research in this proposal will develop the next generation of surgical bioadhesive technology and claim a stake in the estimated US$ 4 billion market. The project outcomes will enhance Australia's reputation in the biomedical field and will have world-wide social and health care benefits by ultimately allowing better functional healing through bioadhesives that can be effectively applied rapidly and consistently.Read moreRead less
Policing Migration in Australia: an analysis of onshore migration policing networks. Recent events concerning the wrongful detention and deportation of Australian citizens have drawn attention to the significant impact of the enforcement of immigration controls within Australian communities.

Recent events concerning the wrongful detention and deportation of Australian citizens have drawn attention to the significant impact of the enforcement of immigration controls within Australian communities. However, this dimension of law enforcement has received little or no attention from academic researchers. An improved understanding of the nature and dynamics of migration policing will provide social benefits through the promotion of good relations with ethnic minority communities and the accountable exercise of statutory powers. This understanding is crucial if institutions of social regulation are to adapt to the challenges of policing a society which is not only multicultural but also increasingly globally interconnected.Read moreRead less

This project aims to improve health in sheep and reduce on-farm losses for Australian producers, by developing new serological tests for chlamydial infections in sheep. These infections can result in significant on-farm losses and loss of trade in the live export industry. Currently, surveillance of chlamydial infections is hindered by outdated serological tools that are unreliable and difficult to interpret. The serological tests to be developed aim to be species-specific tests to detect the most important chlamydial sheep pathogens. This in turn endeavours to improve domestic surveillance, reducing on-farm losses and costs, and improve market opportunities for Australian sheep exporters as well as informing veterinary populations on best practice treatment.Read moreRead less
