Summary
Respiratory infections caused by multidrug-resistant Gram-negative bacteria are major health problems for Australians. Colistin is the last-resort defense in most cases. However, parenteral administration of colistin will cause serious side effects. This proposal applies an interdisciplinary approach using aerosol particle engineering, functional lung imaging and antimicrobial pharmacology to develop and characterise novel inhaled powder formulations of colistin and its rational combinations.
New materials for manipulating intracellular communication. 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.

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
Designing dendrimer-based lymphatic drug vectors as improved treatments for metastatic cancer. 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 an ....Designing dendrimer-based lymphatic drug vectors as improved treatments for metastatic cancer. 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.

Summary
We have discovered a potent antimalarial compound class. In this research plan we will improve their metabolic stability such that we can progress them as potential oral cures for malaria. We will also elucidate their mechanism of action and this will aid therapeutic development.
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
CSI-Sydney: New Technologies To Treat Chronic Sinus Infection

Funding Amount
$412,213.00
Summary
Chronic sinus infection (CSI) is prevalent and results in severe discomfort and pain for many Australians; yet amazingly, has no specific cure or effective treatment. Our multi-disciplinary research team and an Australian health and medical research company, (AFT Pharmaceuticals) have partnered to develop a novel device that specifically targets the sinuses and a formulation capable for simultaneously removing mucus, dispersing biofilms and killing bacteria in the nasal cavities.
The role of electrostatic charge in airway deposition of aerosols. This project aims to unravel the importance of electrostatic charge in controlling deposition of aerosols in the respiratory tract. The expected outcome is a validated mathematical model for accurately predicting deposition behaviour of charged aerosol particles in human airways. Findings may ultimately be used to underpin novel prevention measures to reduce lung deposition of inhaled hazardous airborne particles to significantly ....The role of electrostatic charge in airway deposition of aerosols. This project aims to unravel the importance of electrostatic charge in controlling deposition of aerosols in the respiratory tract. The expected outcome is a validated mathematical model for accurately predicting deposition behaviour of charged aerosol particles in human airways. Findings may ultimately be used to underpin novel prevention measures to reduce lung deposition of inhaled hazardous airborne particles to significantly reduce health risks and costs. They may also be used to enable the development of new inhalation technologies based on electrostatic charge to improve aerosol drug delivery to the lungs of patients with respiratory diseases.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
Novel Inhalation Formulation Of Bacteriophages Against ‘superbugs’ Causing Respiratory Infections

Funding Amount
$563,621.00
Summary
Emergence of superbugs has led to life-threatening respiratory infections that are resistant to most antibiotics. There is an urgent need for alternative treatments not relying on antibiotics. Bacteriophages (or ‘bacteria eaters’) are natural predators of bacteria and are unaffected by antibiotic resistance. This multi-disciplinary project will develop novel therapeutics using inhaled bacteriophages against bacterial infections in the lungs.
