Controlling biodeterioration of cultural materials:
The use of free-radical based treatments to inhibit the communication pathways of biofilms
This research, is being conducted by PhD candidate Caroline Kyi under the supervision of Prof. Carl Schiesser, Assoc. Prof Robyn Sloggett and Ms Sharon Cather, through both the School of Chemistry (Free Radical Chemistry Biotechnology an ARC Centre of Excellence) and the School of Historical Studies (Centre for Cultural Materials Conservation).
Biofilms are assemblages of microorganisms that assist in the colonisation and potential damage and degradation of materials to which they are attached. Free-radicals such as nitric oxide have been identified as inhibitors of biofilm formation. Investigation, assessment and application of this free-radical in the treatment of the biodeterioration of cultural materials forms the basis of this project.
