Nanodiamonds are a wound’s best friend

2 July 2019, By Amanda Abraham.

Band-aids and bandages are remarkable. A simple invention allows us to cover, treat and protect injuries until they have time to heal. But they come with a big drawback – the only way we can check how well the wound is healing, is by removing them.

This means that sometimes infections are detected only after they take hold, which can lead to increased recovery times and the need for additional medications and care.
Now imagine a technology that enables us to track the healing process without needing to remove the bandage.

This technology is being worked on by a group of CNBP researchers based at RMIT University who presented their research at a Physics in the Pub event held in Hawthorn last week.

The team explained that by using nanodiamonds in a ‘smart dressing’, researchers are able to detect temperature changes within or surrounding a wound – a common indication of infection – without removing the bandage.

This would give doctors and nurses the ability to track the healing progress without having to remove and re-apply the dressing.

Dr Amanda Abraham, who presented alongside Qiang Sun, Daniel Stavrevski and Donbi Bai, explained that the topic was chosen because “almost everyone has experienced the pain of band-aid removal. Using nanodiamonds could save the patient further discomfort, and speed up the healing process by providing treatment only when needed.”

Physics in the Pub is an informal, light-hearted night where physicists, astronomers, theoreticians, engineers and educators share their love of science over a refreshing beverage. The event is supported by the AIP, and ARC Centres of Excellence CNBP, OzGrav, FLEET and Exciton Science.

New CNBP researcher at RMIT

16 August 2018:

CNBP welcomes its newest recruit at RMIT University, Dr Amanda Abraham.

She will work with A/Prof Brant Gibson, CNBP Deputy Director and his team, where she will utilise her expertise to explore the biological applications of fluorescent nanomaterials including nanodiamonds, as well as collaborate across the wider CNBP community.

Amanda completed her PhD at RMIT University where she studied the long-term effects of phytochemical coated silver nanoparticles on mammalian cells. She was awarded the Prof CNR Rao Postgraduate Research Excellence Award for her PhD research. This award is given to an RMIT Graduate Sstudent for outstanding contributions in the application of Nanotechnology.

She has also worked as a post-doctoral researcher with Prof. Vipul Bansal, Director of the Sir Ian Potter NanoBioSensing Facility at RMIT University, where she investigated the wound healing capabilities of silver nanoparticle coated fabrics for use as wound dressings.

Her expertise includes mammalian cell culture, confocal microscopy, flow cytometry, protein quantification, assessing gene expression and nanoparticle characterisation.

Welcome to the CNBP team Amanda!
