Despite significant research being directed toward cancer treatment, 7.6 million people died world wide in 2007. Early detection and treatment is widely recognised as being effective in significantly reducing mortality rates. Biomedical imaging techniques are routinely used for detection and staging of many cancers. However, greater sensitivity is required so that these techniques can be applied to very early detection of tumours. To overcome this short-coming the next generation of imaging probes will be developed, which will require fundamental investigations in polymer and nanomaterials science to maximise imaging sensitivity and extend probe functionality. Successful outcomes will lead to significant benefits to healthcare in Australia.Read moreRead less
