Development of metal probes for the selective recognition of DNA. Transition metal complexes with large aromatic ligands have recently been shown to bind DNA by intercalation. However, controversy continues over their base sequence and groove selectivity. We will synthesise a range of chiral metal complexes and screen these against combinatorial oligonucleotide libraries to determine their base sequence selectivity. The information obtained will help us design better intercalators that can be us ....Development of metal probes for the selective recognition of DNA. Transition metal complexes with large aromatic ligands have recently been shown to bind DNA by intercalation. However, controversy continues over their base sequence and groove selectivity. We will synthesise a range of chiral metal complexes and screen these against combinatorial oligonucleotide libraries to determine their base sequence selectivity. The information obtained will help us design better intercalators that can be used as sensitive molecular probes and may find application as antitumour drugs. Binding interaction between the complex and DNA will be studied by NMR spectroscopy.Read moreRead less
Active polymer surfaces for control of fluid movement. The realisation of a diverse array of remote or portable chemical/biological monitoring systems depends on the development of low power fluid management protocols. The use of appropriate conducting polymer surfaces should enable this to occur. We envisage the integration of these fluid management platforms into portable, remote autonomous monitoring systems for environmental industrial and biomedical applications.
Design and Synthesis of Ionic Liquids for Use in Photoelectrochemical Cells Based on Inherently Conducting Polymers. We propose to evaluate the electrochemistry of photoactive polythiophenes recently synthesised by us in a range of ionic liquids. This knowledge will be used to design and synthesise customised ionic liquids with the properties required to enhance the photoelectrochemical efficiency of devices based on substituted polythiophenes. We expect our findings to lead to the development ....Design and Synthesis of Ionic Liquids for Use in Photoelectrochemical Cells Based on Inherently Conducting Polymers.

Inhibitors of enzymes in the lysine biosynthetic pathway. Recent reports of increasing bacterial resistance to antibiotics highlight the need for continual development of new antibacterial agents. Inhibitors of the biosynthesis of the amino acid lysine - an essential component of bacterial proteins and cell wall - may provide a novel class of antibiotics. This project describes investigations of the mechanism of the first two enzymes in the lysine biosynthetic pathway and the design and synthesi ....Inhibitors of enzymes in the lysine biosynthetic pathway.

Mass Spectrometric Investigations of Conformation and Dynamics of Biological Complexes. The new collaboration between the leading mass spectrometry groups at University Wollongong and Cambridge University will benefit both partners. Researchers at Wollongong will have access to an ion mobility mass spectrometry technology not currently available in Australia that will contribute to our understanding of complicated cellular processes such as chromosome replication.

The new collaboration between the leading mass spectrometry groups at University Wollongong and Cambridge University will benefit both partners. Researchers at Wollongong will have access to an ion mobility mass spectrometry technology not currently available in Australia that will contribute to our understanding of complicated cellular processes such as chromosome replication. The researchers' experience with this technology will pave the way for introduction of the technology to Australia and benefit the wider scientific community in wide-ranging projects such as development of new antibiotics and vaccines. Students from both institutions will benefit from experiencing science from an international perspective.Read moreRead less
Advanced materials and structures for terahertz science and technology. Anthrax, explosives, water, cancer all have characteristic signatures in the terahertz (THz) part of the electromagnetic spectrum. Security, defence, agriculture, medicine are some of the fields where THz science and technology are booming. THz developments offer enhanced national security, prosperity and quality of life. The lack of strong sources of THz radiation is the main factor hampering wider application of THz metho ....Advanced materials and structures for terahertz science and technology. Anthrax, explosives, water, cancer all have characteristic signatures in the terahertz (THz) part of the electromagnetic spectrum. Security, defence, agriculture, medicine are some of the fields where THz science and technology are booming. THz developments offer enhanced national security, prosperity and quality of life. The lack of strong sources of THz radiation is the main factor hampering wider application of THz methods. In this project two university research teams come together to develop more efficient THz emitters. The Darmstadt team will prepare novel materials and structures and the Wollongong team will evaluate them and provide feedback for the next iteration.Read moreRead less

Single Molecule Studies of Replisomal Function. It has recently become possible to watch the copying of DNA molecules with a specialized microscope in real time. This process requires assembly of a complex molecular machine on the DNA, followed by triggering of its function, and yields exquisitely detailed information about how the machine works. In this new collaboration between scientists in Australia and the U.S.A., we will assemble these machines on single DNA molecules, watch how they work ....Single Molecule Studies of Replisomal Function. It has recently become possible to watch the copying of DNA molecules with a specialized microscope in real time. This process requires assembly of a complex molecular machine on the DNA, followed by triggering of its function, and yields exquisitely detailed information about how the machine works. In this new collaboration between scientists in Australia and the U.S.A., we will assemble these machines on single DNA molecules, watch how they work and simultaneously measure the very small forces that the machines generate. This will give Australian scientists access to a new technology for studying molecular machines.Read moreRead less
Identification of structural proteins in the tissue cyst wall of Toxoplasma gondii. Most infections with Toxoplasma gondii are asymptomatic, however, infection during pregnancy can lead to miscarriage or blindness, deafness and mental retardation in the developing baby. Furthermore, in AIDS patients, toxoplasmosis is the leading cause of fatal encephalitis as the normally dormant tissue cysts are reactivated in the absence of an effective immune system. In Australia, it has been estimated that ~ ....Identification of structural proteins in the tissue cyst wall of Toxoplasma gondii. Most infections with Toxoplasma gondii are asymptomatic, however, infection during pregnancy can lead to miscarriage or blindness, deafness and mental retardation in the developing baby. Furthermore, in AIDS patients, toxoplasmosis is the leading cause of fatal encephalitis as the normally dormant tissue cysts are reactivated in the absence of an effective immune system. In Australia, it has been estimated that ~30% of the population is infected with T. gondii and the occurrence of congenital toxoplasmosis is 0.2% of live births, which translates to roughly 500 cases/year. Our research will identify structural proteins in Toxoplasma cyst walls that will lead to the design of new strategies to control the diseases caused by these parasites.Read moreRead less
