Pro-Fluorescent Aryl Nitroxides: New Probes for Polymer Lifetime and Kinetics Research. Internal aryl rings present in novel probes developed for this project impart fluorescence which is efficiently and internally quenched by the presence of a paramagnetic nitroxide group. Scavenging of radicals by the nitroxide however "switches on" the fluorescence and this enables powerful new fluorescence-based detection levels for the technique of nitroxide free radical scavenging. Such sensitivity is a ....Pro-Fluorescent Aryl Nitroxides: New Probes for Polymer Lifetime and Kinetics Research. Internal aryl rings present in novel probes developed for this project impart fluorescence which is efficiently and internally quenched by the presence of a paramagnetic nitroxide group. Scavenging of radicals by the nitroxide however "switches on" the fluorescence and this enables powerful new fluorescence-based detection levels for the technique of nitroxide free radical scavenging. Such sensitivity is applicable to polymerization kinetics studies, as well as providing new means for the determination of materials lifetimes. The development of pro-fluorescent markers as indicators for polymer degradation would be a significant outcome for materials where component failure has a major negative impact.Read moreRead less
Engineered Polymer Nanoparticles: A Potent Weapon Against Cancer. Cervical cancer is the commonest cause of cancer death in women under the age of 50 worldwide, the 8th most common cancer among women in Australia, and is the leading cause of cancer death in Aboriginal women. While a vaccine is available to prevent HPV-mediated disease, it would not impact upon death rates for at least 25 years. The systemic delivery of RNAi offers to best opportunity to solve this problem. The delivery devices w ....Engineered Polymer Nanoparticles: A Potent Weapon Against Cancer. Cervical cancer is the commonest cause of cancer death in women under the age of 50 worldwide, the 8th most common cancer among women in Australia, and is the leading cause of cancer death in Aboriginal women. While a vaccine is available to prevent HPV-mediated disease, it would not impact upon death rates for at least 25 years. The systemic delivery of RNAi offers to best opportunity to solve this problem. The delivery devices will be designed with precision and function to meet the delivery needs in vivo. These polymer structures will be suitable for use in drug and gene delivery providing Australian products with advanced features and capabilities, significantly improving product performance.Read moreRead less
Synthesis of nanocomposite polymers with targeted properties. This project aims to synthesise novel nanocomposite polymers by living radical polymerisation in water and to understand the way polymer microstructure and nanomorphology control material properties. This will provide the enabling science so that nanomaterials with targeted properties can be tailor-made for biomedical and speciality-coatings applications, and thus dispense with the current trial-and-error methodology. The innovations ....Synthesis of nanocomposite polymers with targeted properties. This project aims to synthesise novel nanocomposite polymers by living radical polymerisation in water and to understand the way polymer microstructure and nanomorphology control material properties. This will provide the enabling science so that nanomaterials with targeted properties can be tailor-made for biomedical and speciality-coatings applications, and thus dispense with the current trial-and-error methodology. The innovations in this project are the novel synthesis of complex polymer architectures in water, and the first quantitative and qualitative structure-property correlations for such materials. This will also result in a deepened understanding of the mechanisms governing the formation of these nanocomposites.Read moreRead less
