The approach incorporates graphene based biomaterials with tunable electrical and biological properties within supportive three-dimensional cellular microenvironments, greatly enhancing the electrical interactions between cells and the electrode. The electrical properties of nerve cells will be probed using our three-dimensional graphene network, providing insight into the the brain-machine interface. This project is important as it directly addresses the inherent limitations of current electrode designs.Read moreRead less

Smaller, more sophisticated, lifetime-implantable bionic devices capable of being placed at the site of therapeutic delivery will facilitate new or improved opportunities for treatment of disease. Three critical areas of research aim to be explored in pursuit of this goal will be addressed within this study: introduction of new fabrication materials that enable devices to conform to the anatomy of the targeted site of therapeutic delivery; improved means of addressing the data and energy transfer needs of devices implanted in confined spaces; and innovation of novel sensors for testing and monitoring of atmospheric conditions within the implant to anticipate and safely manage issues relating to a breach of hermetic encapsulation barriers.Read moreRead less

Biological determinants of the safety and stability of neuroprosthetic stimulation electrodes. Performance of cochlear implants and the quality of sound perceived by patients is strongly related to electrode impedance. Electrode impedance fluctuates relative to the implant electrical activity, but the mechanisms which cause this are not clear. This project aims to investigate the role of protein adsorption in electrode performance, including impedance and material dissolution.

Performance of cochlear implants and the quality of sound perceived by patients is strongly related to electrode impedance. Electrode impedance fluctuates relative to the implant electrical activity, but the mechanisms which cause this are not clear. This project aims to investigate the role of protein adsorption in electrode performance, including impedance and material dissolution. To enable these investigations a new biomimetic analogue of the perilymph (cochlea fluid) is intended to be developed. Additionally, the project aims to investigate two strategies to minimise impedance changes: small pulse electrode cleaning and antifouling coatings. Understanding and control of factors influencing electrode stability aim to facilitate next-generation implant designs.Read moreRead less
Chip-scale implantable bionics for next generation therapeutic neural prostheses. Australia has an unmatched reputation as a world leader in neuroprostheses. Most notable of these is the bionic ear and, more recently, leading edge research towards a bionic eye.

Australia has an unmatched reputation as a world leader in neuroprostheses. Most notable of these is the bionic ear and, more recently, leading edge research towards a bionic eye. This project will combine the research strengths and experiences from both the hearing and visual bionics fields to address the main obstacles that prevent the number of electrical stimulation channels (equating to the number of frequencies heard by the deaf, and the number of spots of light seen by the blind) from increasing. The study will improve our understanding of the electrode-tissue interface, the life-long implantablity, and electrical circuitry that will allow future bionic devices to significantly improve their performance.Read moreRead less

Summary
This project aims to develop infection-resistant coatings that can be applied to a wide range of biomedical devices used in human health care. Novel antibacterial compounds from Australian plants (genus Eremophila) will be coated as thin layers onto model materials used for biomedical device fabrication, then onto real-life biomedical products and evaluated for ability to deter colonization by biofilm-forming human pathogenic bacteria.

The aim of this research is to provide a simple method for creating complex 3D cell cultures for in vitro cell based assays using 3D printing. A versatile polymer system as a bioink made from entirely commercially available components, will be advanced that gives a full range of soft tissue mimics and which can be dynamically change on-demand after printing of the 3D cell cultures. The latter will provide in vitro mimics of in vivo events never previously possible with more realistic models of what is found in vivo. Applications are in fundamental cell biology, studying diseases and developing new drugs. The outcomes from this research will be new knowledge on designing cheap extracellular matrix mimics and high throughout 3D cell assays.Read moreRead less
