Understanding platinum dissolution in biomedical stimulating electrodes. Platinum is the main material used in electrodes for neurostimulators like the cochlear implant. Platinum electrodes can experience dissolution during implantation, which can impact on their function. The mechanisms governing this dissolution process are complex and still not fully understood. This research aims to understand the chemical, electrical and biological factors that impact on platinum dissolution in electrodes. ....Understanding platinum dissolution in biomedical stimulating electrodes. Platinum is the main material used in electrodes for neurostimulators like the cochlear implant. Platinum electrodes can experience dissolution during implantation, which can impact on their function. The mechanisms governing this dissolution process are complex and still not fully understood. This research aims to understand the chemical, electrical and biological factors that impact on platinum dissolution in electrodes. It will also develop new 3D models to simulate conditions in the human body for more rapid testing of electrodes. The new knowledge generated will improve the accuracy of predictions of platinum dissolution, develop new approaches for minimising dissolution, and contribute to reducing need for animal experimentation.Read moreRead less
Biomimetic blood bag materials for prolonged platelet storage. Platelet storage is limited to five to seven days before there is a reduction in viable platelets. This results in a continual mismatch between supply and demand resulting in patients in remotes areas or those that have rare phenotypes missing out on platelets. It also results in the wastage of platelets because they expire before they can be used clinically. This project aims to extend the platelet shelf life beyond seven days by de ....Biomimetic blood bag materials for prolonged platelet storage. Platelet storage is limited to five to seven days before there is a reduction in viable platelets. This results in a continual mismatch between supply and demand resulting in patients in remotes areas or those that have rare phenotypes missing out on platelets. It also results in the wastage of platelets because they expire before they can be used clinically. This project aims to extend the platelet shelf life beyond seven days by developing biomimetic blood bag materials that reflect the natural molecular structures of blood vessels through the use of novel synthetic and biological materials. With the realisation of longer platelet storage times, this project aims to have significant impacts on the health and economic benefits of Australians.Read moreRead less
Controlling the adhesome to regulate cell fate on biomaterials. Mesenchymal stem cell-based tissue engineering practices are hampered worldwide by the lack of appreciation and understanding of the matrix-mediated cues that must be provided during adhesion and spreading to drive cells to definitive tissue end points. This project will address these knowledge deficiencies by combining high throughput array technologies, a set of tailorable self-assembling biomaterials and real-time biosensors to r ....Controlling the adhesome to regulate cell fate on biomaterials. Mesenchymal stem cell-based tissue engineering practices are hampered worldwide by the lack of appreciation and understanding of the matrix-mediated cues that must be provided during adhesion and spreading to drive cells to definitive tissue end points. This project will address these knowledge deficiencies by combining high throughput array technologies, a set of tailorable self-assembling biomaterials and real-time biosensors to rapidly, at high resolution, elucidate how mechanotransductive cues determine the fate choice of mesenchymal stem cells, and furthermore, how to manipulate them with smart biomaterial design to achieve desired outcomes for tissue engineering.
