Convergence of biomaterials and immunology: a technology platform for delayed burst release of vaccines. A large challenge in vaccination, particularly in wildlife such as for the growing problem of Chlamydia in koalas, is to provide the necessary booster shots. This project will develop implants that will be inserted under the skin at the time of the first shot, and will spontaneously burst later to release the booster shot to provide protection.
Improving immune response to vaccines by selective targeting of epithelial regions with the Nanopatch. Vaccination protects us from infections like measles and flu. In principle, it could protect us from all diseases, even from skin cancer and arthritis. In practice, however, vaccines to diseases like cancer have largely proved ineffective. One problem is that we don't really understand how the body's immune system responds to vaccination. Our aim, therefore, is to investigate changes in the imm ....Improving immune response to vaccines by selective targeting of epithelial regions with the Nanopatch. Vaccination protects us from infections like measles and flu. In principle, it could protect us from all diseases, even from skin cancer and arthritis. In practice, however, vaccines to diseases like cancer have largely proved ineffective. One problem is that we don't really understand how the body's immune system responds to vaccination. Our aim, therefore, is to investigate changes in the immune system when a vaccine enters the skin, as might happen by injection. Experimenting with laboratory mice and a special vaccine-injecting Nanopatch that is attached to each mouse's ear, we are starting to understand how a vaccine affects the immune cells in the skin. In the future we plan to apply this knowledge to improve vaccination in people.Read moreRead less
Optimising the body's immune response with a Nanopatch that delivers biomolecules to the skin. The team is developing a new improved way to vaccinate against deadly infectious diseases such as influenza and malaria. They believe their Nanopatch technology will boost the power of seasonal influenza vaccination and could even solve vaccine shortages in an influenza pandemic. This is because the Nanopatch needs much less vaccine per person than a conventional syringe. They also predict that vaccine ....Optimising the body's immune response with a Nanopatch that delivers biomolecules to the skin. The team is developing a new improved way to vaccinate against deadly infectious diseases such as influenza and malaria. They believe their Nanopatch technology will boost the power of seasonal influenza vaccination and could even solve vaccine shortages in an influenza pandemic. This is because the Nanopatch needs much less vaccine per person than a conventional syringe. They also predict that vaccines delivered with a Nanopatch will require less refrigeration than conventional vaccines and can be safely administered by individuals without medical training, making the benefits of vaccination accessible to more people more cheaply, even in remote areas.Read moreRead less
Micro-nanoprojection patches for minimally-invasive and targeted delivery of genes and drugs to skin cells: from concept to technology platform. This project will address key science questions on the recently patented micro-nanoprojections patch, establishing it in Australia as a world leading technology in the rapidly growing and important field of gene and drug delivery.

This project will address key science questions on the recently patented micro-nanoprojections patch, establishing it in Australia as a world leading technology in the rapidly growing and important field of gene and drug delivery. Unique internationally-competitive science outcoumes and research training will be generated at the interfaces between bioengineering, nanotechnology, pharmaceutical science and immunology. Ultimately, the project will allow improved treatment of major diseases (e.g. vaccination and immunotherapy of asthma). Achieving these health benefits by commercial pathways is expected to benefit the Australian community and emerging Biotechnology industry-creating highly valued career opportunities for Australians.Read moreRead less
Towards direct imaging of neuronal currents with MRI. This project aims to develop novel neuronal current magnetic resonance imaging (nc-MRI) methods that harness the oscillatory behaviour of neuronal magnetic fields. Current methods of detecting neuronal activity in the living human brain have limited spatial and temporal resolution. Use of nc-MRI aims to overcome these limitations by imaging the effects on the MRI signal of small transient magnetic fields associated with neuronal activity. Sig ....Towards direct imaging of neuronal currents with MRI. This project aims to develop novel neuronal current magnetic resonance imaging (nc-MRI) methods that harness the oscillatory behaviour of neuronal magnetic fields. Current methods of detecting neuronal activity in the living human brain have limited spatial and temporal resolution. Use of nc-MRI aims to overcome these limitations by imaging the effects on the MRI signal of small transient magnetic fields associated with neuronal activity. Signal-to-noise ratio is at the limits of detectability using current imaging systems and nc-MRI is yet to be convincingly demonstrated. An integrated framework for simulating nc-MRI in the visual cortex is expected to be developed.Read moreRead less

This project aims to advance our understanding of the poorly understood neural circuits that enable fine motor control in humans. To obtain this knowledge, new platform technology will be developed to capture the full kinematics of the hand during concurrent functional magnetic resonance imaging at ultra high-field. This device will allow testing of fundamental theories describing the canonical microcircuits involved in hand motion. Expected outcomes include new evidence of mirror neurons and observation of predictive error signals in the motor cortex. This new knowledge paves the way towards improved computer-brain interface technology which is likely to create benefits through translation to applications such as artificial limb control.Read moreRead less
Patient-specific biomechanical modelling for improved treatment of spinal deformity. Spinal deformities negatively affect social acceptance, physical and mental wellbeing in children and adolescents. The direct costs of spinal deformity surgery are approximately $30 million per year in Australia, yet poor treatment outcomes due to post-operative complications incur a much higher cost as patients with persistent pain and disability face a lifetime of dependency and reduced ability to work. The pa ....Patient-specific biomechanical modelling for improved treatment of spinal deformity. Spinal deformities negatively affect social acceptance, physical and mental wellbeing in children and adolescents. The direct costs of spinal deformity surgery are approximately $30 million per year in Australia, yet poor treatment outcomes due to post-operative complications incur a much higher cost as patients with persistent pain and disability face a lifetime of dependency and reduced ability to work. The patient-specific biomechanical modelling techniques developed in this project will reduce complications and improve correction for Australian children who undergo spinal deformity surgery. Better treatment outcomes will ensure quality of life, health and productivity for spinal deformity patients throughout their entire lives.Read moreRead less

However, because the spine is very complex our understanding of its mechanics and the causes of back pain are still limited. This project will investigate the anatomy and activity of the spinal muscles and the behaviour of the intervertebral disc in living subjects using innovative Magnetic Resonance Imaging techniques. Significant outcomes will be new definitive descriptions of the detailed anatomy of the spine and its mechanisms. This will enhance the accuracy and detail of models under development for predicting spinal function following disease, injury or surgical procedures.Read moreRead less
