We've developed a coating for medical implants inspired by the beginnings of life
Many people trace their ancestry to try and get some insight into who they are and where they came from. We ask questions like ‘was my great, great grandfather a convict?’ or ‘did my great aunt twice-removed really marry her second cousin?’
They’re important questions, no doubt, but they pale into comparison when pondering the evolution of life on Earth. Just where did it all – including us – come from?
Prebiotic chemists ask these questions for a living. They try to look back as far as possible to understand how Earth went from being formed, to having life on it. And they reckon we can all be traced back to a pile of goo – as explained in this video:
This fact we all come from goo is something that’s impressive enough to ponder in itself. But a team of our material scientists didn’t just stop there: they wanted to know how this life-forming goo could be used to solve some real-world challenges.
The incredibly ancient group of molecules that make up the goo – known as prebiotic compounds – have been studied intensively since their discovery several decades ago. For the first time, Australian researchers have uncovered a way to use these molecules to assist with medical treatments.

Our scientists developed an innovative new coating that could be used to improve medical devices and implants, thanks to these prehistoric molecules.
According to lead researcher Dr Richard Evans, hundreds of thousands of Australians receive medical implants like bone replacements, catheters and pacemakers every year.
The human body is a complex system so there’s a lot to consider when implanting artificial parts. Reducing the likelihood of infection and ensuring the body doesn’t reject implants are ongoing medical challenges.
“That’s why coatings on these implants are needed to help them to do their job.
The coating could be applied to medical devices to improve their performance and acceptance by the body. This could assist with a range of medical procedures.
“The non-toxic coating is adhesive and will coat almost any material making its potential biomedical applications really broad,” Richard said.
The researchers also experimented with adding silver compounds, in order to produce an antibacterial coating that can be used on devices such as catheters to avoid infections.
The coating process that the scientists developed is very simple and uses methods and substances that are readily available. This means biomedical manufacturers can produce improved results more cost effectively compared to existing coatings.
This research opens the door to a host of new biomedical possibilities that are still yet to be explored, so we’re seeking to partner with biomedical manufacturers to exploit this technology.
