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
Nanoengineering of Biomaterial Surfaces to Tailor Innate Immune Responses. The overarching aim of this project is to provide a mechanistic understanding of how surface nanotopography affects inflammatory responses. Recently, we showed that surface nanotopography induced conformational changes in adsorbed proteins can activate or deactivate immune cells.

The overarching aim of this project is to provide a mechanistic understanding of how surface nanotopography affects inflammatory responses. Recently, we showed that surface nanotopography induced conformational changes in adsorbed proteins can activate or deactivate immune cells. These exciting findings are important because they show that it may be possible to engineer the nanotopography of a biomedical device surface in a manner which leads to a desired and predictable level of inflammation. The outcomes of the project will create new fundamental knowledge that in the future can instruct the development of the next generation of biomaterials capable of controlling and directing the body’s inflammatory responses.Read moreRead less
