Polymer Research Leading To More Efficient Cancer Drugs
The organic chemists have been awarded Australia's highest science honour for their revolutionary work in changing the structures of polymer chains. Their discoveries could also help develop longer lasting paint, reusable contact lenses and smoother lubricants.
Professor Rizzardo, 67, an Italian-born scientist said he was very excited about one application of the polymer research, which will help oncologists deliver cancer drugs to the site of the tumour.
''These polymers are designed in such a way that it delivers the therapeutic agent to the cancer site.''
The pair's research established that by controlling the structure, composition and properties of polymers and plastics, it was possible to essentially custom-build plastics.
So broad are the applications that the work has already been adopted by 60 companies, including multi-nationals L'Oreal, IBM, Dulux and DuPont. The research is also an integral part of more than 500 patents, with the potential to generate hundreds of millions of dollars in royalties.
On the new contact lenses, Prof Rizzardo said, ''The lenses need to transmit oxygen and water to keep the eye healthy, they need to be soft and comfortable and completely transparent and physically strong. You can wear them for a long, long time - these products are very close to coming on the market,'' he said.
