Microprobe and Nanoprobe Studies on Intracellular Disease Processes and Their Treatment. Breakthrough microprobe and nanoprobe technologies, involving X-ray, visible and infrared light can focus into different components of mammalian cells in order to interrogate the biochemistry that is occurring therein.

Breakthrough microprobe and nanoprobe technologies, involving X-ray, visible and infrared light can focus into different components of mammalian cells in order to interrogate the biochemistry that is occurring therein. Each of the different wavelengths of light provides complementary biochemical information that enables a deeper understanding of changes in cells that occur as a function of drug treatments and disease processes. This will provide unprecedented information as to where drugs go and how they are transformed inside cells that, in turn, may revolutionalise the way in which new drugs are designed that have higher specificity and fewer side effects.Read moreRead less

Raman and synchrotron spectroscopy of nano-scale drug interactions and molecular processes in single living cells. The need for potent low-cost drugs is ever increasing, yet effective ways to screen for new drugs remain elusive. A spectroscopic approach to screening drugs in living cells would seem a logical alternative to chemically based and morphological methods that are the status quo. In this context we are developing methodology to analyse molecular target sites in single living cells for ....Raman and synchrotron spectroscopy of nano-scale drug interactions and molecular processes in single living cells. The need for potent low-cost drugs is ever increasing, yet effective ways to screen for new drugs remain elusive. A spectroscopic approach to screening drugs in living cells would seem a logical alternative to chemically based and morphological methods that are the status quo. In this context we are developing methodology to analyse molecular target sites in single living cells for two of the most devastating diseases to afflict human kind, namely malaria and cancer. New ways of rapidly screening drugs in living cells prior to clinical trials will save an enormous amount of time, money and ultimately lives.Read moreRead less
Novel Mass Spectrometric Approaches to the Study of Protein-Protein Interactions. Protein-protein interactions mediate all fundamental cellular processes, yet the structural complexity of protein assemblies mean they are often difficult to characterise using traditional analytical methods. This project will develop and demonstrate novel mass spectrometric approaches towards a molecular level description of the structure and interactions of biological protein complexes, which in turn may underpi ....Novel Mass Spectrometric Approaches to the Study of Protein-Protein Interactions. Protein-protein interactions mediate all fundamental cellular processes, yet the structural complexity of protein assemblies mean they are often difficult to characterise using traditional analytical methods. This project will develop and demonstrate novel mass spectrometric approaches towards a molecular level description of the structure and interactions of biological protein complexes, which in turn may underpin the rational design of drugs for the treatment of a range of human health conditions. This project will also provide training of young researchers to the highest international standards in mass spectrometry and protein science, for benefit to Australian industry and research.Read moreRead less
