There’s been an explosion in the use of endoscopes in medical procedures over the past 30 years, from examining the liver and stomach (known as laparoscopy) to minimally invasive surgery. The use of these instruments is firmly established as an imaging technique that allows surgeons to ‘see’ inside the body, allowing them to recognise lymph nodes they need to avoid, or assess the health of lung tissue, for example.

“Diamonds are forever”. This is not only true for the gemstones themselves, but also for the colouration and fluorescence that many diamonds display. Dr Philipp Reineck uses this rare property to engineering tiny diamond particles with unlimited fluorescence. Continue reading
A host of diseases – like meningitis, diabetes, cystic fibrosis, Alzheimer’s disease, even some cancers – are ultimately caused by problems at the cellular level. Hence, understanding what is happening inside cells is essential. Observing cells under a microscope helps, but what medical researchers would really like to do is see processes inside cells in minute detail. Continue reading
Dr Asma Khalid enjoys wearing silk dresses, and appreciates diamonds for their beauty —but she never expected both silk and diamonds to end up being the cornerstone of her work as a physicist. Yet they have opened up a whole new way to see deep in the body, sense infections on the skin and even deliver drugs in controlled amounts. Continue reading

Few materials shine light like diamond, and researchers are beginning to harness this property to explore the brain in minute detail.
At the Centre for Nanoscale BioPhotonics, Marco Capelli uses these tiny crystals to measure magnetic fields surrounding neurons with the goal of having them side-by-side, leading to fresh insights on cell communication. Continue reading

Researchers have found a way to identify multiple cell signalling proteins using a single cell rather than the billions of cells used previously.
The new measurement technology, developed by researchers at the ARC Centre of Excellence for Nanoscale Biophotonics, brings precision medicine a step closer.
“Cells secrete various messenger molecules, such as cytokines. They may indicate the presence of a disease or act as a driver of key therapeutic effects,” says Dr Guozhen Liu, lead author of paper detailing the technology.
The method, termed OnCELISA, uses antibodies attached on specially engineered cell surfaces to capture cytokine molecules before they have a chance to disperse away from the cell.
The secreted messenger proteins such as cytokines are reported, at the single cell level, by using fluorescent magnetic nanoparticles.
Cytokines secreted from cells play a critical role in controlling many physiological functions, including immunity, inflammation, response to cancer, and tissue repair.
The OnCELISA system can be used for ultrasensitive monitoring of cytokine release by individual cells, and it can also help discover cell populations with therapeutic value.
“The ability to identify and select cell populations based on their cytokine release is particularly valuable in commercial cell technologies and it can help develop unique products, such as future non-opioid pain relief” says Dr Liu.
“Importantly, our design uses commercially available reagents only, so it can be easily reproduced by others,” she adds.
While the published work focuses on specific proinflammatory cytokines IL-6 and IL-1β, the method is potentially suitable for a broad range of other secreted proteins and cell types.
The new technique represents an advance on traditional methods such as the enzyme-linked immunosorbent assays (ELISA) that detect average levels of secreted molecules from cell ensembles.
The OnCELISA takes the ELISA approach to its absolute extreme, by detecting cytokines on the surface of individual, single live cells.
The publication has been reported by prestigious iScience journal and can be found at https://www.sciencedirect.com/science/article/pii/S2589004219303578.
Publication Title: A Nanoparticle-Based Affinity Sensor that Identifies and Selects Highly Cytokine-Secreting Cells

Summary: We developed a universal method termed OnCELISA to detect cytokine secretion from individual cells by applying a capture technology on the cell membrane. OnCELISA uses fluorescent magnetic nanoparticles as assay reporters that enable detection on a single-cell level in microscopy and flow cytometry and fluorimetry in cell ensembles. This system is flexible and can be modified to detect different cytokines from a broad range of cytokine-secreting cells. Using OnCELISA we have been able to select and sort highly cytokine-secreting cells and identify cytokine-secreting expression profiles of different cell populations in vitro and ex vivo. We show that this system can be used for ultrasensitive monitoring of cytokines in the complex biological environment of atherosclerosis that contains multiple cell types. The ability to identify and select cell populations based on their cytokine expression characteristics is valuable in a host of applications that require the monitoring of disease progression.
The CNBP and its researchers are taking part in a wide range of activities for National Science Week.
This Thursday 8 August researcher Dr Wei Deng from UNSW Sydney will explain how nanotechnogy is changing how we treat cancer, as part of Inspiring Australia’s Talking Science series.
It will be held at the Max Webber Library, in Blacktown, Sydney. More details here.
On Sunday, 11 August, Adelaide University’s Lyndsey Collins-Praino will host Kids Navigate Neuroscience, an event at which children aged 4-10 can explore how the brain works in a fun and hands-on way by participating in a series of interactive neuroscience exhibits.
On Tuesday 13 August explore medical brain research by joining Dr Lindsay Parker, a researcher at Macquarie University, as she discusses how she is trying to create better medicines for Alzheimer’s, chronic pain and brain cancer, by only targeting the unhealthy cells in the brain.

There is a fun evening next Friday, 16 August, at the Adelaide Medical School, University of Adelaide, where you can explore the neuroscience of sex, drugs and salsa dancing.
A series of interactive exhibits will address questions such as, what role does the brain play in sexual attraction? Can you salsa dance your way to a healthy brain? How does the brain perceive different flavours when drinking wine, and how can pairing wine with different foods alter this perception?
Also next Friday, 16 August, the whole family is invited to see some amazing short videos on a massive screen in a free National Science Week Event hosted by STEMSEL Foundation Braggs Lecture Theatre, University of Adelaide AI Light Science Spectacular.
You will find out how the eye works, how NASA finds planets in other solar systems and how detected the edge of the Universe.
You will also explore light, from nanoscale biophotonics with CNBP research fellow Dr Roman Kostecki to exploring the Universe with Dr Jerry Madakbas, a photonics physicist who builds night vision sensors for NASA.
You can book through Eventbrite.
Also on Friday night:
What role does the brain play in sexual attraction? Can you salsa dance your way to a healthy brain? How does the brain perceive different flavours when drinking wine, and how can pairing wine with different foods alter this perception?
These days, you can’t seem to walk through the aisle of a grocery store without being bombarded by newspaper and magazine headlines touting the latest and greatest breakthrough in neuroscience research. But how can you tell fact from fiction?
Join us for this Big Science Adelaide event, held at the Adelaide Health and Medical Sciences (AHMS) building at the University of Adelaide, where we’ll explore the answers to these questions and many more!
