Powder blending for dry powder inhalers: a new approach for direct control of powder structure. Over 80 per cent of pharmaceutical products involve the processing of powders. This project will generate new knowledge of how to assemble fine and cohesive particles into the structure required for dry powder inhaler products, leading to the development of new low-cost medicines in Australia and the Asia Pacific region.
The Fluid-Particle Mechanics of a Synthetic Jet-based Dry Powder Inhaler. This project aims to untangle the fundamental principles that govern the fluid mechanics and particulate interactions in a novel concept chip-based micro-zero-net-mass-flux (micro-ZNMF) jet-assisted dry powder inhaler (DPI). Respiratory diseases affect 6.2 million Australians. The treatment of these diseases is hampered by the poor efficiency of current delivery systems, with conventional DPI devices exhibiting sub-optimum ....The Fluid-Particle Mechanics of a Synthetic Jet-based Dry Powder Inhaler. This project aims to untangle the fundamental principles that govern the fluid mechanics and particulate interactions in a novel concept chip-based micro-zero-net-mass-flux (micro-ZNMF) jet-assisted dry powder inhaler (DPI). Respiratory diseases affect 6.2 million Australians. The treatment of these diseases is hampered by the poor efficiency of current delivery systems, with conventional DPI devices exhibiting sub-optimum performance, delivering typically less than 20% of the loaded dose to the target site, the lungs. The new fundamental knowledge resulting from this research will enable the engineering of a high-efficiency groundbreaking DPI, with the potential to be fully adaptive user-specific benefiting millions of Australians.

Supersaturated and non-digestible dispersions in the intestinal lumen: new mechanisms to reduce variability in the rate and extent of drug absorption. This project will design new polymers to be included in capsule formulations to prevent the precipitation of drugs in the intestine after their oral administration. This new technology will reduce the incidence of side-effects and ensure that patients absorb the correct dose of drug regardless of whether they take the drug before or after food.
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
Drug Targeting to Immune Cells Using Modified Inulin Particles. Vaxine Pty Ltd is an Australian biotechnology company that has discovered specific particulate forms of inulin that are efficiently internalised by human immune cells. This project aims to exploit cell migration to injury and infection sites by attaching drugs to inulin particles creating a targeted drug delivery system. This system will transport drugs specifically to afflicted areas, reducing systemic concentrations of drugs and h ....Drug Targeting to Immune Cells Using Modified Inulin Particles. Vaxine Pty Ltd is an Australian biotechnology company that has discovered specific particulate forms of inulin that are efficiently internalised by human immune cells. This project aims to exploit cell migration to injury and infection sites by attaching drugs to inulin particles creating a targeted drug delivery system. This system will transport drugs specifically to afflicted areas, reducing systemic concentrations of drugs and hence the risks of dose related side effects. This project has potential both to improve healthcare and to encourage the growth of expertise in the biotechnology industry in Australia.Read moreRead less
Bioproduction and bioavailability of steroidal saponins, bioactives in herbal medicines. Steroidal saponins are a class of natural products that are common constituents of many herbal medicines and have been associated with many biological activities. Comprehensive studies into their biological activities are hampered by the small quantities available through isolation and the complexity of synthesis. The aim of this project is to identify, isolate and express the biosynthetic genes responsible ....Bioproduction and bioavailability of steroidal saponins, bioactives in herbal medicines. Steroidal saponins are a class of natural products that are common constituents of many herbal medicines and have been associated with many biological activities. Comprehensive studies into their biological activities are hampered by the small quantities available through isolation and the complexity of synthesis. The aim of this project is to identify, isolate and express the biosynthetic genes responsible for the critical steps in the synthesis of these compounds in the herbs themselves. This will allow for production of steroidal saponins using the isolated enzymes, facilitate biological studies and allow the production of critical standards required by the herbal industry for validation and regulation of herbal extracts.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.
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).

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
