Abstract:
This seminar will introduce our recently developed a number of new platform technologies based on mordent polymer chemistry. One example will be an antibacterial and peptide-based star polymer (Figure 1a) we developed recently and it can kill multi-drug resistant gram-negative superbugs without causing toxicity to healthy cells (Nature Microbiol. 2016, 1, 16162). The 2nd example will be photo-induced controlled polymerization using RAFT agent without using any initiators (Figure 1b; Macromolecules 2015, 48, 3864). The other examples include continuous assembly of polymer (CAP) technology, which creates macromolecular architectures in 3D forms. The final example is PEG based hydrogel technology used as tissue engineering scaffolds. Such material has formed substrate for a synthetic cornea transplant which is now close to stage 1 human trials. Specific examples will be presented for these platform technologies.

The research interests of Greg Qiao are in the area of synthetic polymer science and engineering. His research applies various polymerization techniques, including controlled free radical polymerizations, to synthesize novel polymeric architectures, biodegradable and functional polymers. His industrial research is in the synthesis of the nanogels for automotive coatings and the novel hydrogels for biological separations.
The research in biopolymers is focused on applications in tissue engineering.Greg leads an internationally recognized Polymer Science Group in the Department and is currently the president of the Victorian Polymer Group under Royal Australia Chemical Institute. He is also a project leader of the Cooperative Research Centre for Greenhouse Gas Technologies (CO2CRC) and CRC for Polymers.
