New med-tech zinc sensor developed

29 September 2017:

A new zinc sensor has been developed by CNBP researchers, which will allow for a deeper understanding of the dynamic roles that metal ions play in regulating health and disease in the living body.

The research, published in the journal ACS Omega reports that the newly designed chemical sensor can detect and measure zinc levels in cells. It also has the functionality and portability to take continuous or repeated measurements within a single biological sample.

“This makes the sensor potentially suitable for use in future diagnostic tools that could open up entirely new windows into the body,” says lead author of the research Dr Sabrina Heng (pictured), Research Fellow at the ARC Centre of Excellence for Nanoscale BioPhotonics (CNBP), at the University of Adelaide.

Automated image analysis aids bladder cancer diagnosis

28 September 2017:

An automated image analysis technique has been developed by CNBP researchers (lead researcher Dr Martin Gosnell pictured) that is able to aid in the diagnosis of bladder cancer, and could potentially reduce the number of biopsies being taken unnecessarily.

Want a better camera? Just copy bees!

4 July 2017:

Check out the latest buzz about bees and their extra light-sensing eyes! CNBP CI Prof Andy Greentree is coauthor on a new paper in PNAS, which identifies how the eyes and brains of honeybees work together, to process colour information.

“If we can design technology to mimic the way bees do this, we’ll be able to create better cameras and image-processing systems for drones and robots,” say the researchers in an article on the science news channel ‘The Conversation‘.

 

New nanoparticle discovery to aid super-resolution imaging

Prof Jim Piper26 April 2017:

Researchers at the ARC Centre of Excellence for Nanoscale BioPhotonics (CNBP), Macquarie University, the University of Technology Sydney (UTS), Peking University and Shanghai Jiao-tong University have made a breakthrough in the development of practical super-resolution optical microscopy that will pave the way for the detailed study of live cells and organisms, on a scale 10 times smaller than can currently be achieved with conventional microscopy.

Reported in Nature, the international team of researchers has demonstrated that bright luminescent nanoparticles can be switched on and off using a low-power infrared laser beam, and used to achieve images with a super resolution of 28nm.

Professor Jim Piper (pictured), leader of the research team at Macquarie University and the CNBP sees these nanoparticles as having new unique properties. “These allow researchers to see well beyond normal limits of standard microscopes. It will let you see deeper and more clearly at the cellular and intra- cellular level—where proteins, antibodies and enzymes ultimately run the machinery of life.”

Nanoscale sensor detects disease

28 March 2017:

A new nanoscale sensor has been developed by CNBP researchers that can help detect cytokines — molecules that play a critical role in cellular response to infection, inflammation, trauma and disease.

Leader of the project A/Prof Guozhen Liu (pictured) said the release of certain cytokines by the body is frequently symptomatic of a disease or health-related issue. “Monitoring cytokine secretions at the cellular and subcellular level has enormous value in our understanding of basic physiology and how the body is actually working.”

New ‘smart needle’ to make brain surgery safer

20 January 2017:

A new high-tech medical device to make brain surgery safer has been developed by CNBP researchers at the University of Adelaide.

Prof Robert McLaughlin (pictured), leader of the project, was featured in Science Daily, stating, “”We call it a smart needle. It contains a tiny fibre-optic camera, the size of a human hair, shining infrared light to see the vessels before the needle can damage them.”
