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.

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
The Role Of Nuclear Architecture In The DNA Damage Response

Funding Amount
$561,966.00
Summary
The goal of the proposed research is to understand how dynamic changes to the chromatin genome packaging network, interact with the DNA damage response and gene expression machinery, to repair damaged DNA and the impact this has on cancer biology. To do so we are combining cutting edge molecular biology techniques with innovative novel microscopy methods developed by our research team, that far exceed the spatiotemporal resolution currently used to study chromatin biology.

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
How Replication Stress Activates The Mitotic Telomere DNA Damage Response To Kill Cancer Cells

Funding Amount
$486,467.00
Summary
We discovered a novel mechanism linking stress during DNA replication to difficulties with the cell division process, and identified how this turns on DNA damage response signals from the chromosome ends (i.e. “telomeres”). We have further identified that we can exploit this mechanism to kill cancer cells. In this project we will explore this newly discovered mechanism and identify how it can be targeted for therapeutic purposes.
Miniaturised biosensors with high selectivity . This project aims to develop a technological platform for the fabrication of miniaturised and flexible sensors that enable the quantitative detection of important bioactive compounds such as fatty acids and biogenic amines. By utilising multi-enzymatic reactions in solid phase and engineering task-specific inks, chemiresistive sensors will be printed seamlessly as a whole. The sensors will respond to complex target biomolecules via a series of enzy ....Miniaturised biosensors with high selectivity . This project aims to develop a technological platform for the fabrication of miniaturised and flexible sensors that enable the quantitative detection of important bioactive compounds such as fatty acids and biogenic amines. By utilising multi-enzymatic reactions in solid phase and engineering task-specific inks, chemiresistive sensors will be printed seamlessly as a whole. The sensors will respond to complex target biomolecules via a series of enzymatic reactions through which the analyte will convert to much simpler, reactive and hence measurable molecules. This project will enable to design miniaturised sensors for point-of-care detection of biomolecules that cannot be yet evaluated by the end users.Read moreRead less
Molecular approaches to solving current and emerging problems in the epidemiology and diagnosis of Marek's disease in Australia. Marek's disease (MD) is a ubiquitous viral disease of chickens that is currently controlled in meat chickens by blanket vaccination of all chickens. However, as has happened overseas, the efficacy of the HVT vaccine being used in Australia is breaking down resulting in subclinical and clinical losses due to MD. To assist industry deal with this situation we propose to ....Molecular approaches to solving current and emerging problems in the epidemiology and diagnosis of Marek's disease in Australia. Marek's disease (MD) is a ubiquitous viral disease of chickens that is currently controlled in meat chickens by blanket vaccination of all chickens. However, as has happened overseas, the efficacy of the HVT vaccine being used in Australia is breaking down resulting in subclinical and clinical losses due to MD. To assist industry deal with this situation we propose to develop novel molecular methods for the quantification of Marek's disease viruses (MDV) in the host and the environment, to use these methods to design effective early monitoring systems for MD in broilers that predict disease and performance outcomes, and to develop an epidemiological model that will predict the spread and severity of MD as failure of vaccinal protection progresses.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.

This project aims to develop a novel biosensor prototype based on CYBERNOSE® technology to rapidly identify volatile traces of illicit drugs and precursor chemicals in concealed environments. The CYBERNOSE® technology employs sensors using the highly sophisticated and sensitive olfactory receptors of microscopic nematode worms linked to an optoelectronic detector. The need for rapid, non-contact screening devices to detect and identify illicit drugs and precursors entering Australia has never been greater. Law enforcement agencies should directly benefit from the capability to more rapidly screen people and cargo, improving efficiency of illicit drug detection and protection of our borders.Read moreRead less
