Rapid detection of rare-event cells by strong UP-conversion
encoded nano-radiators (SUPER Dots): finding a needle in a haystack. Current diagnostic tests are not sensitive enough to detect cancer in its very early stages or early recurrence following treatment. The new technologies developed by this project will be able to find single cancer cells in blood and urine samples heralding a new era in medical diagnostics.
Devil Facial Tumour Disease: Cytogenetic Clues to Transmission and Development. Devil Facial Tumour Disease is a fatal cancer that is decimating Tasmanian devils. Preliminary work suggests that tumours from different animals have identical sets of highly abnormal chromosomes, including a giant marker chromosome. We will use DNA probes to 'paint' abnormal tumour chromosomes to discover markers for diagnosis, and identify genes contributing to tumour development and immune suppression. Most import ....Devil Facial Tumour Disease: Cytogenetic Clues to Transmission and Development. Devil Facial Tumour Disease is a fatal cancer that is decimating Tasmanian devils. Preliminary work suggests that tumours from different animals have identical sets of highly abnormal chromosomes, including a giant marker chromosome. We will use DNA probes to 'paint' abnormal tumour chromosomes to discover markers for diagnosis, and identify genes contributing to tumour development and immune suppression. Most importantly, we will test our hypothesis that tumours all arose from a single ancestral cancer cell that is transmitted between animals. A cellular transmission has frightening implications for spread of disease, but will allow us to develop appropriate therapeutic strategies to save a unique Australian marsupial from extinction.Read moreRead less
The multiplexed diagnosis of arbovirus infections using combinatorial probes. Viruses that cause serious diseases such as hemorrhagic fever or encephalitis must be quickly identified. Diagnostic tests based on DNA hybridisation are accurate and can be rapid but they are expensive. We will test a method for simplifying DNA tests and increasing their capabilities. DNA probes for detecting arboviruses will be designed at the ANU using new bioinformatic methods and their reliability will be model ....The multiplexed diagnosis of arbovirus infections using combinatorial probes. Viruses that cause serious diseases such as hemorrhagic fever or encephalitis must be quickly identified. Diagnostic tests based on DNA hybridisation are accurate and can be rapid but they are expensive. We will test a method for simplifying DNA tests and increasing their capabilities. DNA probes for detecting arboviruses will be designed at the ANU using new bioinformatic methods and their reliability will be modelled using all the available genetic information. Computer predictions will be experimentally tested in the PANBIO laboratory by using the probes to detect viral nucleic acids. The influence of virus genome complexity will be investigatedRead moreRead less
Rapid CYBERNOSE ® detection of illicit drugs and precursor chemicals. Rapid CYBERNOSE ® detection of illicit drugs and precursor chemicals. 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 det ....Rapid CYBERNOSE ® detection of illicit drugs and precursor chemicals. Rapid CYBERNOSE ® detection of illicit drugs and precursor chemicals. 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
Development of new tools for surveillance of chlamydial infections in sheep. 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 ser ....Development of new tools for surveillance of chlamydial infections in sheep. 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
New Methods for Directed Molecular Evolution of Novel Protein Functions. Novel ribosome-based techniques can be used to carry out test-tube evolution of proteins with new structures and functions. The methods rely on (a) physical association of individual nucleic acid molecules with the particular protein molecules they encode, (b) selection of proteins with new functions, and (c) recovery of the attached genetic code. This project will address several issues that currently limit use of these fr ....New Methods for Directed Molecular Evolution of Novel Protein Functions. Novel ribosome-based techniques can be used to carry out test-tube evolution of proteins with new structures and functions. The methods rely on (a) physical association of individual nucleic acid molecules with the particular protein molecules they encode, (b) selection of proteins with new functions, and (c) recovery of the attached genetic code. This project will address several issues that currently limit use of these frontier technologies for evolution of new protein products that have a wide range of practical applications.Read moreRead less
