Forces on Particles in Flows Traversing a Magnetic Field. The influence of magnetic fields on the motion of particles near surfaces will be examined using quiescent and shear flow fields at low Reynolds numbers. This theoretical and experimental study will produce a precise theoretical understanding of the motion, including the shear induced lift-force, and hence a basis for controlling the interaction of the particle with the adjacent surface. This fundamental study will provide the foundations ....Forces on Particles in Flows Traversing a Magnetic Field.

This theoretical and experimental study will produce a precise theoretical understanding of the motion, including the shear induced lift-force, and hence a basis for controlling the interaction of the particle with the adjacent surface. This fundamental study will provide the foundations needed to apply magnetic fields to a broad range of emerging problems in nano-technology and biotechnology, and help train and educate a student at the PhD level in the area.Read moreRead less

The 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 interdisciplinary nature of this project will also result in a unique training program for the researchers included in this grant. Such experience is in great demand, particularly in Australia where the burgeoning start-up discovery industry is critically short of personnel with skills in drug delivery.Read moreRead less

This will enhance the standing of Australian biomedical research in the pharmaceutical world and directly facilitate a partnership between Monash and Capsugel in commercialisation of the outcomes of the project. The project will also train Australian scientists in skills that are in great demand in the developing pharmaceutical industry in Australia.Read moreRead less
Enhanced drug delivery using nanoparticulate dendrimer vectors. Many drug candidates fail during development because of low and variable absorption after oral administration. This project seeks to investigate the utility of specialised nanometer-sized macromolecules (dendrimers), to facilitate the improved delivery of drug molecules where low aqueous solubility is the principle limitation to drug absorption and will also be explored as vectors to specifically target drugs to intestinal lymphoid ....Enhanced drug delivery using nanoparticulate dendrimer vectors. Many drug candidates fail during development because of low and variable absorption after oral administration. This project seeks to investigate the utility of specialised nanometer-sized macromolecules (dendrimers), to facilitate the improved delivery of drug molecules where low aqueous solubility is the principle limitation to drug absorption and will also be explored as vectors to specifically target drugs to intestinal lymphoid (immune) tissue. This project will link the drug delivery expertise of Monash University with the experience in dendrimer design of the Australian biotechnology company Starpharma to provide concrete delivery solutions for the rapidly expanding biotechnology industry in Australia.Read moreRead less
Oral Insulin Delivery facilitated by Enteric Coating using Dense Gas Technologies. Insulin dependant diabetes is a rapidly growing disease. The current method for insulin delivery to the patient is by injection, which is inconvenient. Oral delivery of insulin is a more acceptable method. It is proposed to develop a dense gas technique to coat insulin with a pH sensitive polymer to protect it from the acidic environment of the stomach. Insulin can then be released at the high pH of the intestin ....Oral Insulin Delivery facilitated by Enteric Coating using Dense Gas Technologies. Insulin dependant diabetes is a rapidly growing disease. The current method for insulin delivery to the patient is by injection, which is inconvenient. Oral delivery of insulin is a more acceptable method. It is proposed to develop a dense gas technique to coat insulin with a pH sensitive polymer to protect it from the acidic environment of the stomach. Insulin can then be released at the high pH of the intestine when the polymer is dissolved. Particle size control is feasible by dense gas processes by manipulating operating parameters. Advantages include low residual solvent and manufacture at ambient temperatures.Read moreRead less
Self organization in (bio)molecular systems: Simulating the folding and aggregation of peptides, proteins and lipids. Molecular self-assembly is a basic property of living systems. Most proteins fold spontaneously and then further self-organize into functional complexes, effectively biological machines. Understanding how this occurs is a fundamental theoretical challenge with widespread application. Work will focus on developing methodology to simulate, computationally, the folding and aggrega ....Self organization in (bio)molecular systems: Simulating the folding and aggregation of peptides, proteins and lipids. Molecular self-assembly is a basic property of living systems. Most proteins fold spontaneously and then further self-organize into functional complexes, effectively biological machines. Understanding how this occurs is a fundamental theoretical challenge with widespread application. Work will focus on developing methodology to simulate, computationally, the folding and aggregation of peptides, proteins, and lipids. The aim is to accurately predict the structures of small peptides in solution and to refine crude models of larger molecules (complexes). This will facilitate the development of peptide based therapeutics and is essential in exploiting the growing volume of genetic information in biology and medicine.Read moreRead less
Therapeutic approaches to treat human immunodeficiency virus infection: development of HIV-1 integrase inhibitors. This project aims to assist the development of new anti-HIV drugs, which would benefit the 15000 Australians and over 40 million people worldwide who are currently infected with this terrible disease.

There is a clear need for development of novel antibiotics which are capable of treating the increasingly prevalent strains of pathogenic bacteria that are resistant to currently available drugs. In this proposal we will design novel inhibitors of bacterial enzymes that are required for the correct folding of a variety of proteins and test the effects of these molecules on enzyme activity, bacterial growth and antibiotic resistance. Specific inhibitors of these enzymes constitute a novel strategy for the treatment of bacteria that have developed resistance to existing antimicrobial drugs.

Drug Delivery Devices : Hydrogels manufactured utilising Dense Gas Technologies. Many drugs are rapidly eliminated from the human body, and would benefit from being released over a long period of time. In this study, formulations to deliver drugs will be developed, using hydrogels: highly cross-linked, water saturated polymers.

Many drugs are rapidly eliminated from the human body, and would benefit from being released over a long period of time. In this study, formulations to deliver drugs will be developed, using hydrogels: highly cross-linked, water saturated polymers. The polymers to be investigated are based on ingredients suitable for ingestion. Hydrogels are in common use as external therapeutic devices, such as contact lenses or wound dressings. However, hydrogels are not commonly in use as ingested drug delivery devices due to problems with the existing technologies, such as toxicity of ingredients. These problems will be addressed in this study.Read moreRead less
