Soft materials containing hierarchy via 3D sacrificial micro-moulding. The project seeks to develop sophisticated new polymeric materials and devices not possible using current manufacturing techniques. Biomaterials based on hydrogels are ideal substrates for synthetic extra-cellular matrices due to their high water content.

The project seeks to develop sophisticated new polymeric materials and devices not possible using current manufacturing techniques. Biomaterials based on hydrogels are ideal substrates for synthetic extra-cellular matrices due to their high water content. However, one of the challenges hindering the use of hydrogels is reproducing the transport properties found in natural tissue with hierarchical features such as vascularisation. To address this, the project plans to develop a 3D moulding process for generating soft materials containing precise channels decorated with defined molecules. Intended outcomes include a fundamental understanding of the 3D moulding process, and new polymers and advanced tools for bioengineers for future applications such as tissue transplants, cell guides for treating spinal cord injuries, soft robotics and microfluidic devices to study cancer metastasis.

Switching the light on cartilage repair. Osteoarthritis is a leading cause of pain and disability in adults and affects 15 per cent of the Australian population. This project will develop a revolutionary new approach to treat joint disorders using smart materials and stem cells. The novel materials and techniques developed will help Australia maintain its leading edge in biotechnology.
Sequence-defined polymers and green chemistry. This project aims to synthesise polymers that have precise chemical structure and mimic the biological activities of natural biopolymers like peptides and proteins. Monomer sequence regulation in these natural biopolymers is important in biology and necessary for crucial features of life, such as molecular recognition, self-replication and catalysis.

Combinatorial design of multivalent polymers for cell receptor clustering. This project aims to design biologically active multivalent peptide-polymer conjugates. This project will use an enzyme to conduct the reactions in tiny volumes in the open air, and prepare and screen large libraries of different architectures for their ability to kill cancer cell lines through the clustering of death receptor proteins on the cell surface. Such combinatorial techniques have been crucial to the development ....Combinatorial design of multivalent polymers for cell receptor clustering. This project aims to design biologically active multivalent peptide-polymer conjugates. This project will use an enzyme to conduct the reactions in tiny volumes in the open air, and prepare and screen large libraries of different architectures for their ability to kill cancer cell lines through the clustering of death receptor proteins on the cell surface. Such combinatorial techniques have been crucial to the development of small molecule drugs. This project aims to apply this technique to well-defined macromolecules, studying their structure-activity relationships, and could lead ultimately to the generation of lead compounds for therapeutics with high commercial relevance.Read moreRead less

Summary
New dimensions in organic bionics. The advent of the next generation of medical bionic devices is critically dependent on advances in multifunctional organic materials that, like living systems, provide spatial and temporal control. These advances will provide a platform to revolutionise medical treatments such as nerve and muscle regeneration, with impact on neural prosthetics.
Learning from nature: creating synthetic viruses using self-assembled structures with branched or dendritic glycopolymers on their surfaces. Viruses are nature's clever nanoparticles. Viruses use glycoproteins to find and invade their host cells. This project will aim to mimic nature by generating nanoparticles that carry synthetic glycopolymers on the surface to create better drug delivery carriers.
Engineering drug transportation behaviour in polymeric gel systems. In collaboration with Seagull Technologies, this project aims to engineer, study and mathematically model ultrasound-assisted biomacromolecule transport behaviour within polymeric gel systems, which may be useful in new drug delivery methods.

In collaboration with Seagull Technologies, this project aims to engineer, study and mathematically model ultrasound-assisted biomacromolecule transport behaviour within polymeric gel systems, which may be useful in new drug delivery methods. The intended outcome is a novel set of polymeric gel systems, which can reversibly bind a wide variety of drugs (small molecules, nucleic acid based drugs, proteins), in which drug release is triggered by an electric potential and drug transport is controlled by means of sonophoresis. The main advantage of drug delivery via sonophoresis is elimination of risks associated with injections such as infection and damage to local tissue, and elimination of patient discomfort, pain and fear.Read moreRead less

Polyion complex micelles as smart nano-sized drug carriers for proteins. Novel treatments against diseases are often based on proteins, which are unstable against hydrolysis and sometimes difficult to deliver across the cell membrane. The aim of the project is to create a smart drug carrier that can encapsulate proteins efficiently. A range of block copolymers will be synthesised that are able to condense a positively charged protein resulting in the formation of polyion complex micelles.

Novel treatments against diseases are often based on proteins, which are unstable against hydrolysis and sometimes difficult to deliver across the cell membrane. The aim of the project is to create a smart drug carrier that can encapsulate proteins efficiently. A range of block copolymers will be synthesised that are able to condense a positively charged protein resulting in the formation of polyion complex micelles. The polymer structure will be fine-tuned to create a drug carrier that releases the protein efficiently once inside mammalian cells. The outcome will be the enhanced understanding of the relationship between polymer structure and the activity of the protein and ultimately the design of an advanced and smart drug carrier.Read moreRead less
