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
Developing novel aerosol inhalers for pulmonary drug delivery from the fundamental understanding of powder dispersion mechanisms. The project seeks to understand how powder aerosol inhalers can be significantly improved. The outcome will provide therapeutic benefits to the Australian community for better treatment of respiratory diseases and facilitate environmentally friendly technology since these inhalers do not require any harmful organic solvents to operate.
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
Ultra-low dose dry powder inhaler technology for the treatment of respiratory diseases. Drug molecules are being developed for respiratory diseases, which are highly potent but beyond our capability in terms of delivery. Using a combination of high-end particle engineering and characterisation approaches, coupled with computational modelling, the project will develop a theoretical model that can be used to deliver ultra-low doses to the lungs.
One for all and all for one: Engineering a drug delivery platform for DNA vaccines to the lung. Vaccination using next generation DNA plasmids is hindered by the lack of a suitable delivery technology. This project aims to develop a low-cost vaccination platform that can deliver any DNA vaccine via inhalation.

High efficiency dry powder particles that contain a novel synthetic cell penetration enhancer and incorporate the drug delivery vehicle in a disposable inhalation device will be engineered. The project aims to help develop a fundamental understanding of the properties that govern interactions in these systems, and a number of in vitro tools that can be used by the wider scientific community. Ultimately, a single platform that can be used for the vaccination of any disease will be created.Read moreRead less
Production of nano-composite particles for inhalational delivery of combination drugs. The project seeks to create a new particle engineering process for pharmaceuticals. The successful outcome will i) enhance substantially the competitiveness of Australia’s research in functional nanomaterials and advanced biomaterials, and ii) benefit the Australian pharmaceutical industry in developing proprietary pharmaceutical formulations.

This project will explore a novel nano-medicine technology using nanocrystals in liposomes to design new composite particles to enable optimal release of antibiotics delivered by inhalation. Respiratory infection caused by multidrug-resistant bacteria is a major health problem worldwide. Controlled-release products using liposomes simplify dose regimen and enhance bacterial killing. Currently, aerosolised liposomes are limited to liquid forms with limited control over release and stability. The project will provide new technology on manufacturing composite powders of antibiotics that may ultimately lead to the development of effective new treatments against drug-resistant bacteria.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.

Engineering suspended particle sprays through controlled cavitation. This project aims to use cavitation to engineer particle size in sprays of micronised particles suspended in a propellant, and develop a physical mechanism for this process. Understanding how cavitation affects the size of agglomerates in the liquid phase and droplet size in a spray is critical to developing spray devices that require precise control over the final particle size. This will be achieved through high-resolution op ....Engineering suspended particle sprays through controlled cavitation. This project aims to use cavitation to engineer particle size in sprays of micronised particles suspended in a propellant, and develop a physical mechanism for this process. Understanding how cavitation affects the size of agglomerates in the liquid phase and droplet size in a spray is critical to developing spray devices that require precise control over the final particle size. This will be achieved through high-resolution optical imaging techniques and synchrotron X-ray diagnostics. This project is expected to provide physical insight with applications for inhaled and topical pharmaceutical sprays, and industry spray drying of food products.Read moreRead less
Multi-drug dry powder inhalation systems for the effective treatment of chronic obstructive pulmonary disease. Utilising a combination of particle engineering, computer modeling, rapid prototyping and high-speed 3D imaging this project will develop a novel approach to treat chronic obstructive pulmonary disease. A multi-drug particle system whose surface is independent of the drugs incorporated will be optimised in a novel high efficiency inhalation device.
