This will be achieved by developing materials that leverage a previously unexplored mechanism that was recently identified in my lab: the co-engagement of integrin and syndecan-4 cell receptors. We will use these biomaterials to 1) fabricate 3D printed tissue engineering scaffolds with a superior ability to promote the development of new tissue, and 2) create surfaces that will enable us to answer fundamental scientific questions regarding cell adhesion and cell/material interactions.Read moreRead less

This project aims to develop chemistries and fabrication approaches through innovative materials evaluation to develop ultra-low fouling active electrode surfaces. Development of ultra-low fouling surfaces will have significant impact in a range of applications where system or device failure is attributed to fouling. The growing field of bionics, where implantable electronic devices interface directly with the nervous system, is one such device. The expected outcomes will be an understanding of the material requirements that lead to the elimination of protein and cell accumulation at surfaces that degrades the performance and lifetime of these implants. The findings will benefit any application where fouling is a problem.Read moreRead less

The ability to conduct stable, high resolution recording and stimulation within the brain is critically important to the development of technologies that interface electronics with the human body. Devices that interface directly with the brain are increasingly important in brain research, medical monitoring, treatment of neurological diseases or the enormous increase in brain-machine interface technologies. Carbon Cybernetics have developed a high-density neural recording and stimulation array that employs fine carbon fibres as the electrode material. We aim to show that this array can record from the brain indefinitely, without loosing signal quality, and the same array can be used to stimulate the brain to recreate memories or sensations.Read moreRead less

Biology has ways of recognising when a foreign body is present, thus implanted devices need to be camouflaged from the body's immune system. Today's bionic devices fail because they are rapidly rejected. We will use the element of biology, carbon, to construct a new class of technology for future implants. Using a combination of permanent diamond and flexible carbon fibres we will create materials that are invisible to the immune system and last for decades.
