Engineering better sprays for leaf coating: from drop impact to retention. This proposal aims to understand the performance of a unique rheological modifier that can enable an order of magnitude increase in coating efficiency for aerosol sprays while not affecting the quality of droplet formation during spraying. The effect occurs via a dispersed network of fibrous particles in water, providing a weak but useful ability to coat surfaces by responsively adjusting its structure. The material is ex ....Engineering better sprays for leaf coating: from drop impact to retention. This proposal aims to understand the performance of a unique rheological modifier that can enable an order of magnitude increase in coating efficiency for aerosol sprays while not affecting the quality of droplet formation during spraying. The effect occurs via a dispersed network of fibrous particles in water, providing a weak but useful ability to coat surfaces by responsively adjusting its structure. The material is expected to enable a broad array of applications, from agricultural treatments to nasal sprays, by exhibiting responsive behaviour at concentrations much lower than conventional modifiers require. The project will study the responsiveness of the system in single droplet, spray, and coating form as well as an active delivery system.Read moreRead less
Smartdrops - Shaping the future of particle technology. The aim of this project is to develop a particle engineering technology, based on microfluidics, that results in micro-droplets with controlled geometry and morphology. These Smartdrops will be used to target respiratory macrophages for the delivery of inflammatory suppressants, since their dimensions can be controlled to optimise lung deposition and macrophage recognition. The project aims to develop an aerosol inhaler and a series of phys ....Smartdrops - Shaping the future of particle technology. The aim of this project is to develop a particle engineering technology, based on microfluidics, that results in micro-droplets with controlled geometry and morphology. These Smartdrops will be used to target respiratory macrophages for the delivery of inflammatory suppressants, since their dimensions can be controlled to optimise lung deposition and macrophage recognition. The project aims to develop an aerosol inhaler and a series of physico-chemical and in vitro characterisation tools that will be used to study Smartdrop formation, aerosol properties and their interactions with cells. The outcome of this project is intended to be the development of a technology for treating chronic lung inflammation which could also be utilised for a number of other commercial applications.Read moreRead less

Mucus control: Applying concepts from bacteriophage-mucus interactions. This project aims to examine how mucus-adherent bacteriophage interact with bacteria in mucus as a mechanism to manipulate microbiomes. Bacterial infections at mucosal surfaces in animals are a serious global health threat. Traditionally antibiotics have been used to curb mucosal infections, but antibiotic resistance means new therapies are urgently needed. Bacteriophage – viruses that infect bacteria – can kill bacteria and ....Mucus control: Applying concepts from bacteriophage-mucus interactions. This project aims to examine how mucus-adherent bacteriophage interact with bacteria in mucus as a mechanism to manipulate microbiomes. Bacterial infections at mucosal surfaces in animals are a serious global health threat. Traditionally antibiotics have been used to curb mucosal infections, but antibiotic resistance means new therapies are urgently needed. Bacteriophage – viruses that infect bacteria – can kill bacteria and might provide a layer of antimicrobial immunity in animal mucus. The anticipated outcomes are resolving how bacteriophage control bacteria within mucus, and applying concepts to bioengineer mucosal microbiomes.Read moreRead less
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
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.

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
The first integrated multimodal assay for the ultrasensitive detection of dengue contamination of blood. This project will develop the first screening test to check for dengue contamination of blood donations in Australia. This will help ensure safe, continued supply from blood donors, particularly in Queensland where dengue is on the rise.
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

Summary
The influence of crosstalk between protein post-translational modifications on the propagation of molecular signals. The ability of a cell to respond appropriately to its surroundings is a result of interactions between proteins and chemical modifiers termed post-translational modifications (PTM). This project will show how PTM interactions (competition/ cooperation) influence cellular outcomes in response to changes in the environment.

Summary
Spatial control of nanoporous materials for microfabrication. Treatment of numerous medical conditions will be revolutionised by biomedical devices that can deliver or remove selected molecules in precise locations (for example oxygenation of tissues, release of antitumor agents, toxin neutralisation). New lithographic protocols will be developed to enable the use of nanoporous filters directly for such purposes.
