This project aims to identify new techniques for incorporating cell-signalling triggers into macromolecules, therefore enabling the development of next-generation stimuli-responsive nanoparticles that can emit signalling molecules on demand. Harnessing nanomaterials to stimulate specific sub-cellular processes is a neglected area in nanotechnology research. These nanoparticles could potentially be used to deliver signalling molecules for agricultural, pharmaceutical and veterinary applications. The project is expected to develop a new suite of materials that could ultimately be used to improve the yield of important commercial crops, or revitalise the use of medicines limited by their poor side effect profile.Read moreRead less

This project builds on areas of research strength in Australia (nanotechnology and biotechnology/biomaterials) and will add considerably to the expanding Australian expertise-base in dendrimer technology (in which it is a world leader). The project will advance the fundamental science base that underpins dendrimer design and has the potential to deliver substantial benefits in improved drug delivery and therefore health outcomes for Australia. The interdisciplinary nature of this project will also result in a unique training program for the researchers involved. Such experience is in great demand in Australia where the developing biotechnology and nanotechnology industry is critically short of scientists with skills in drug delivery.Read moreRead less
Controlling the spatial distribution of targeting ligands on dendrimer surfaces as a means of dictating cellular recognition and fate. This project seeks to develop next generation targeted drug delivery systems that 'home' to specific target cells, including cancers. Targeted delivery systems have the potential to revolutionise therapy by providing bespoke drug distribution patterns that are tailored to specific diseases and result in enhanced activity and reduced toxicity.
Enabling aerosol delivery of phages to defeat antibiotic-resistant bacteria. This project aims to explore the use of bacteriophages towards producing a safe, natural, and highly effective alternative to traditional antibiotics. Respiratory infections caused by multidrug-resistant Gram-negative bacteria are a major health problem worldwide, and cost Australia over $150 million annually. Some 5,000 Australians die each year from antibiotic resistant infections. The project aims to produce efficac ....Enabling aerosol delivery of phages to defeat antibiotic-resistant bacteria. This project aims to explore the use of bacteriophages towards producing a safe, natural, and highly effective alternative to traditional antibiotics. Respiratory infections caused by multidrug-resistant Gram-negative bacteria are a major health problem worldwide, and cost Australia over $150 million annually. Some 5,000 Australians die each year from antibiotic resistant infections. The project aims to produce efficacious and stable formulations of bacteriophages for easy delivery by inhalation as aerosols with a long shelf-life, making them a commercially viable product. The expected research outcome can lead to an economic and efficient technology to produce phage powders for novel treatment strategies of infections by inhalation.Read moreRead less

Plant plasters: Efficient spray micro-coatings for plant delivery. This proposal will study and apply recently-discovered methods of strongly attaching beneficial chemicals to plant leaves, stalks, and fruit. The materials have an unusually good ability to stick to crop plants and deliver herbicide or pesticide active ingredients more efficiently than standard additives, without toxicity. Recent findings have shown significant health risks from commercial herbicide additives and their run-off in ....Plant plasters: Efficient spray micro-coatings for plant delivery. This proposal will study and apply recently-discovered methods of strongly attaching beneficial chemicals to plant leaves, stalks, and fruit. The materials have an unusually good ability to stick to crop plants and deliver herbicide or pesticide active ingredients more efficiently than standard additives, without toxicity. Recent findings have shown significant health risks from commercial herbicide additives and their run-off into vulnerable ecosystems like the Great Barrier Reef. This project will explain the unusually effective, but simple, adhesion and delivery performance, incorporate the new additives into commercially-relevant formulations for our industrial partner, and work to deliver the materials at relevant manufacturing scales.Read moreRead less

This project aims to implement an innovative approach to modelling ion channel behaviour that employs short, information-rich datasets and parameter inference. Using the hERG potassium channel as a test case, the project will show that this approach is more efficient than current methods and outperforms all published models in independent validations. The project aims to extend on initial implementation to probe the thermodynamics and pharmacology of ion channel gating. The anticipated outcomes are to grow fundamental knowledge of ion channel biophysics and ability to probe ion channel function in silico. The project will build on an emerging collaboration between international leaders in physiology, pharmacology, mathematics and computer modelling. The methodology and fundamental knowledge generated will significantly advance our understanding of the physiology and biophysics of ion channels, while the application of the method will have direct impact in the pharmaceutical industry and regulatory science.Read moreRead less

An attack from all angles! Multiphase particle systems that target respiratory infection. This project will result in advanced inhaled medicines for lung infection. Micron-particles will be engineered to have sustained drug release when deposited at sites of infection, yet avoid natural clearance and defence mechanisms. To study these systems, a series of characterisation, in vitro cell and in silico tools will be developed.
A VAST potential for ion channel drug discovery. The purpose of this project is to bring innovation into the methods used for identifying and characterising novel carbohydrate-based compounds acting at ion channels.
