Doping control in sport is to protect the health, legal and ethical rights of athletes. The use of banned drugs in competitive sports is becoming increasingly sophisticated and the need to counter this provides a stimulus for ground breaking analytical research. This project will exploit mass spectrometry for investigation of methods to distinguish administered peptide hormones from endogenous material and to develop assays for measurement of the peptide hormones, erythropoietin, growth hormone and chorionic gonadotrophin in blood or urine. The outcomes will flow to other areas where trace substance detection is important, such as environmental chemistry, medicine and quality control.Read moreRead less
Identifying tear lipids, their deposition onto contact lenses and their role in the development of dry eye. Lipids provide a critical layer in the human tear film that retards evaporation and helps nourish and protect the eye. We will identify the molecules within this essential "oil slick" to better understand dry eye syndrome and the discomfort associated with wearing contact lenses. This may lead to new treatments for dry eye and novel technologies that provide greater comfort for the ~120,00 ....Identifying tear lipids, their deposition onto contact lenses and their role in the development of dry eye. Lipids provide a critical layer in the human tear film that retards evaporation and helps nourish and protect the eye. We will identify the molecules within this essential "oil slick" to better understand dry eye syndrome and the discomfort associated with wearing contact lenses. This may lead to new treatments for dry eye and novel technologies that provide greater comfort for the ~120,000 Australians who wear contact lenses. This collaborative research directly supports the mission of a respected non-profit organisation (Institute for Eye Research) and will train scientists in world-leading analytical technologies that are essential to Australia's emerging biotechnology industries.Read moreRead less

Summary
800 MHz NMR Spectrometer for Molecular Structure-Function Analyses. An 800 MHz high-resolution nuclear magnetic resonance (NMR) spectrometer equipped with a triple-resonance cryoprobe is required to support the research of 5 universities in the NSW/ACT area. The high magnetic field of the spectrometer is necessary for the study of proteins, protein-ligand complexes and other biomolecular systems of molecular weight >30,000. Projects previously inaccessible due to sensitivity, solubility or resol ....800 MHz NMR Spectrometer for Molecular Structure-Function Analyses. An 800 MHz high-resolution nuclear magnetic resonance (NMR) spectrometer equipped with a triple-resonance cryoprobe is required to support the research of 5 universities in the NSW/ACT area. The high magnetic field of the spectrometer is necessary for the study of proteins, protein-ligand complexes and other biomolecular systems of molecular weight >30,000. Projects previously inaccessible due to sensitivity, solubility or resolution problems will become tractable. The increased turn-around times afforded by the high sensitivity of the cryo-enabled spectrometer make it possible to provide access for Australian institutions that would not otherwise have access to comparable equipment.Read moreRead less
The Application of Chemical Force Microscopy for Monitoring DNA Hybridization: A New Sensing Concept Capable of Detecting Single Molecules. This proposal outlines a method of monitoring DNA sequences with such high sensitivity that a single molecule may be detected. Such sensitivity is achieved using an atomic force microscope (AFM) to measure surface forces. Modifying an AFM tip with a single strand of DNA allows the complementary strand (the target) to be recognized via hybridization to form ....The Application of Chemical Force Microscopy for Monitoring DNA Hybridization: A New Sensing Concept Capable of Detecting Single Molecules. This proposal outlines a method of monitoring DNA sequences with such high sensitivity that a single molecule may be detected. Such sensitivity is achieved using an atomic force microscope (AFM) to measure surface forces. Modifying an AFM tip with a single strand of DNA allows the complementary strand (the target) to be recognized via hybridization to form the double helix. The occurrence of hybridization is determined by differences in surface force measurements compared with when only the single strand of DNA is present. In this way DNA samples can be analyzed without amplification; a major advance for DNA diagnostics.Read moreRead less
