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

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
Understanding bacteriophage deactivation and stabilisation in formulations. Bacteriophages (phages) are viruses that kill pathogenic bacteria without causing harms to the eco-balance. They can provide a safe and highly effective antimicrobial measure for biocontrol when formulated properly.

This project aims to develop a mechanistic understanding of the physicochemical factors responsible for stabilising and deactivating phages in a wide range of formulations. It will create new knowledge on key relationships between phage chemistry, phage-excipient interactions and phage stability. The research outcomes would significantly benefit Australia by enabling commercial development in the high value-adding area of environmentally friendly antimicrobial products.Read moreRead less

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
