Commercialisation workshop outlines opportunities

17 May 2018:

Thursday 17th May saw CNBP, The Institute for Photonics and Advanced Sensing (IPAS) and Adelaide Enterprise come together at the University of Adelaide to jointly host a well-attended Commercialisation Workshop.

The event, with 45 participants comprising CNBP/IPAS researchers, students, Centre Associate Investigators and Chief Investigators looked to provide information, advice and discussion on commercialising technologies successfully, best-practice in starting and exiting start-ups, as well as tips for successful working relationships between academics and industry.

CNBP’s Business Development Manager Mel Trebilcock who helped coordinate the workshop saw the day as a great success.

“Firstly, Adelaide Enterprise provided an overview of a tech transfer office, templates relating to Invention Disclosures, Patents and the step by step process for a researcher ready to start the commercialisation process.”

“Then we had guest speakers – Melissa McBurnie (Brandon Capital) and Stewart Bartlett (from spinout company Ferronova), discuss their history of success and failure along the technology-translation journey, as well as talk about alternate  career pathways for researchers. They both provided some fantastic insights, including the adage that it’s okay to fail but that there is the need to stay positive and focused on your desired research outcomes.”

The afternoon session of the workshop saw attendees break-up into smaller groups and undertake a practical hands-on exercise whereby they had to work-up an invention based on household waste, to fill-out an invention disclosure, and to then provide a pitch to the whole room.

“This allowed for great involvement and interaction with an amazing amount of commercialisation experience being shared by attendees and guests,” says Mel Trebilcock.

New commercialisation workshops are also being planned by the CNBP for August.

“These will help prepare colleagues and collaborators to refine and learn the art of pitches with industry. It will also help them to lead ‘pitch teams’ presenting at a ‘Shark Tank’ style event to be held at this year’s CNBP Conference at Lorne,” she says.

Outreach at Adelaide High School

17 May 2018:

Superstar of STEM and CNBP researcher Dr Sanam Mustafa has taken her outreach skills to Adelaide High School, speaking to approximately 300 Year 9 students (across two sessions) about her scientific activity, her career as a scientist and what it takes to succeed in a University environment.

“My talk was extremely well received by the students and teaching staff,” said Dr Mustafa. “They loved the personal stories and hearing about the light-focused science that we do at the CNBP.”

As part of her outreach activity at the school,  Dr Mustafa also ran an interactive workshop  for students, aimed at illustrating the importance of developing tests to quantify levels of pain for both human and animal populations.

“The students, in groups of about 10 were asked to discuss painful conditions that they had experienced and to try to find a common experience (maybe a paper cut or sprained ankle for instance). I then asked them to rate their pain from a scale of 1-10 to see how this varied within the group to demonstrate the subjectivity,” says Dr Mustafa.

“I then asked the groups to discuss if and why this subjectivity is a problem – such as inability of small children to describe pain, an inaccurate description of pain resulting in the administration of wrong medication and deliberate manipulation of pain scores for drug seeking behaviour.”

“Finally, I told the students how I hoped to develop a test to quantify pain to help overcome this subjectivity and showed them a slide demonstrating the ‘colour of pain’ from our ongoing hyperspectral work.”

“Feedback from the day was extremely positive,” concluded Dr Mustafa. “And it was fantastic to see so many engaged students actively thinking about science and how it has the potential to have such a beneficial and positive impact on society.”

CNBP input into major exhibition

11 May 2018:

The launch of a ground-breaking and unconventional permanent exhibition at Scienceworks titled ‘Beyond Perception: Seeing the Unseen’ had more than a touch of CNBP involvement with RMIT based researchers  A/Prof Brant Gibson and Dr Tony Orth involved in providing information, content and ideas to the exhibition over a 12-18 month planning and implementation period.

The exhibition, reflecting the latest and greatest stories from science and technology, provides interactive, large-scale experiences that reveals the invisible fields and forces that surround us, such as gravitational waves, invisible light, sound and aerodynamics. It also demonstrates current research which is continuing to uncover these amazing and tantalizing worlds.

“The areas where we contributed were around the use of the visible part of the electromagnetic spectrum for optical microscopy applications,” says A/Prof Brant Gibson.

“We looked at the the fact that the diffraction limit of a microscope has now been ‘broken’ with the development of superresolution microscopy such as STED or PALM.”

“It was an absolute pleasure to be involved in this type of activity that takes science out to the broader community,” says A/Prof Gibson.

“The exhibition provides an opportunity for people to immerse themselves and to deeply engage with the exhibition using sound, light and waves in ways which are radically different to other exhibitions I’ve seen.”

Information on the exhibition and how to visit can be found online.

CNBP outreach at MQ ‘Career Ready Day’

10 May 2018:

CNBP’s Dr Annemarie Nadort has shone a light on biophotonics, microcirculation, medical device development and a career in science to an audience of 35 Yr 9-10 high school students, at an outreach session at Macquarie University, May 10th, 2018.

The students, attending the University as a part of a ‘career-ready’ day, were given a quick tutorial on blood and light and were then given a hands-on demonstration of a clinical microcirculation imager that was able to provide a real-time view of red blood cells circulating in capillaries under the tongue.

Students were then given a brief history of the imager’s development and then asked how they could potentially improve a mark-two version of the device from a biological, physics, engineering, IT and software perspective. This explained Dr Nadort was the sort of critical thinking required to kick-start a career in medical device design and development; and the skills that could be learnt from undertaking higher education study.

Feedback from the students was extremely positive. Half a dozen students tried the imager under their own tongues. Seeing the body’s cells operate in real-time on a large screen proved insightful and engaging to all in the room.

Detecting zearalenone (a toxin found in cereals)

1 May 2018:

CNBP PhD student at Macquarie University, Fuyuan Zhang (pictured), is first author on a new paper reporting on the development of magnetic nanobead based fluoroimmunoassays  for detection of zearalenone (a toxin found in cereals).

Journal: Sensors and Actuators B: Chemical.

Publication title: Novel magnetic nanobeads-based fluoroimmunoassays for zearalenone detection in cereals using protein G as the recognition linker.

Authors: Fuyuan Zhang, Bing Liu, Guozhen Liu, Wei Sheng, Yan Zhang, Qi Liu, Shuo Wang.

Abstract: Zearalenone (ZEN) is a type of estrogenic mycotoxin commonly found in cereals. In order to satisfy the need for ultrasensitive detection of ZEN, we developed two novel magnetic nanobeads (MNBs)-based fluoroimmunoassays using protein G (PG) as recognition binder on the sensing interface. One proposed facile strategy is based on a first capture last react (FCLR) procedure while the other is a first react last capture (FRLC) format. Specifically, CdTe/CdS/ZnS quantum dots were synthesized and modified to antigen (OVA-ZEN) as the signal probes. The PG modified MNBs specifically captured the fragment crystallizable region of immunoglobulin G (IgG) with a level of orientation while avoiding the destruction of antibody’s binding sites caused by chemical coupling. Under the optimized conditions, the detection limits of 0.019 ng mL−1 and 0.049 ng mL−1 in the extract solution were obtained for the FCLR and FRLC, respectively. Furthermore, the established methods proved to be successful in detecting ZEN in real cereal samples with the detection limits being 0.6 μg kg−1 and 1.5 μg kg−1 in the FCLR and FRLC, respectively. The performance of the proposed assays was evaluated utilizing commercial ELISA kits with satisfactory results.

A novel, high sensitivity Sagnac-interferometer biosensor

30 April 2018:

A new publication featuring CNBP co-authors (Dr Stephen Warren-Smith pictured left and Prof Heike Ebendorff-Heidepriem) reports on the design and implementation of a novel, high sensitivity Sagnac-interferometer biosensor based on an exposed core microstructured optical fiber (ECF).

Journal: Sensors and Actuators B: Chemical.

Publication title: High-sensitivity Sagnac-interferometer biosensor based on exposed core microstructured optical fiber.

Authors: Xuegang Li, Linh V. Nguyen, Yong Zhao, Heike Ebendorff-Heidepriem, Stephen C. Warren-Smith.

Abstract: A novel, high sensitivity Sagnac-interferometer biosensor based on exposed core microstructured optical fiber (ECF) has been designed and implemented in this paper. The exposed core fiber has noncircular symmetry and thus exhibits birefringence and can form a sensing element within a Sagnac loop interferometer. The exposed-core fiber design provides direct access to the evanescent field, allowing the measurement of bulk refractive index (RI) with a sensitivity of up to −3137 nm/RIU while maintaining the fiber’s robustness. The sensor can also detect the localized refractive index changes at the fiber core’s surface as the result of a biological binding event. We demonstrate the use of this sensor for label-free sensing of biological molecules by immobilizing biotin onto the fiber core as the probe to capture the target molecule streptavidin.

Fellowship supports ongoing study into chronic pain

26 April 2018:

The Centre for Nanoscale BioPhotonics (CNBP), an Australian Research Council Centre of Excellence is pleased to announce that Logan Jenkins, a researcher at Vanderbilt University, USA, is the successful recipient of the CNBP-American Australian Association (AAA) Fellowship for 2018.

The Fellowship, coordinated by the AAA and funded by the CNBP, provides US$30,000 to support an American graduate student, PhD or early career Postdoctoral Fellow who wishes to conduct collaborative research at a CNBP research node in Australia.

In this instance, it will allow Logan Jenkins, who specialises in Biophotonics, to take forward research that will explore how light can be used to control neuronal activity, as well as to examine how such techniques potentially impact the body’s neuroimmune system.

This area of study will directly align with CNBP’s activity in the chronic pain space says Mark Hutchinson, CNBP Director and Professor at the University of Adelaide.

“Within the CNBP we examine the working neuroimmune interface at a cellular level and in particular, how the brain’s immune-like cells are linked to chronic pain, a condition that affects millions of people world-wide,” Professor Hutchinson says.

“We will work closely with Logan to see how his light-based neuronal control mechanisms, and neuroimmune related study, links to our own advanced research in this area.”

Jenkins is looking forward to meeting the CNBP research team in Australia.

“This Fellowship will give me the opportunity to work closely with a prestigious Centre of Excellence and I look forward to conducting some excellent and impactful research. I also hope to build scientific friendships that will lead to ongoing collaborations and discovery,” he says.

Prof Mark Hutchinson welcomed the Fellowship appointment.

“The CNBP seeks to conduct international cutting-edge research in Biophotonics. In order to do this we need to have the best people in the world collaborating with us. This includes rising stars like Logan who comes to us from the Vanderbilt Biophotonics Center, an outstanding organisation which leads the world in ‘neuronal control by light’ investigation.”

“Logan will be based primarily at the University of Adelaide during this Fellowship and will also spend time at CNBP’s other research nodes as he explores his research program in the Centre,” says Professor Hutchinson.

Further information on the United States to Australia Scholarships can be found online at the American Australian Association website. The AAA seeks to build closer USA to Australia ties.

The research is also being supported by the Air Force Office of Scientific Research (AFOSR) and enabled through access to the Australian National Fabrication Facility (ANFF).

Centre outreach encourages a career in science

18 April 2018:

Two fantastic sessions of outreach in two days by CNBP researcher Dr Annemarie Nadort saw 100 Year 11 and Year 12 students learn about biophotonics, blood cells and the skills required to create medical devices that benefit society.

The sessions took place at Macquarie University and were part of a highly successful initiative aimed at encouraging students to undertake higher education learning and potentially develop a career in science.

During the outreach sessions, Dr Annemarie Nadort provided the students with a brief overview of light-based imaging and how it could be best applied to examine blood inside the body. Students were then presented with a real-life case-study on the development of a clinical microcirculation imager. A hands-on demonstration of the device then took place, followed by an interactive group discussion on how the device could be potentially improved with future development. Students were then left with the message that there were many opportunities open to them across the scientific and technology disciplines,  and that they should study in those areas that they were most enthusiastic about.

“I was extremely impressed as to how engaged these students were,” said Dr Annemarie Nadort. “They provided some great answers during the group discussion stage of the session and had really thought through issues and potential solutions. I could see the keenness for science and technology in the room and hopefully my sessions added to that keenness and passion for science. I’d love to see some of these students become the researchers of the future, developing their own fantastic new medical devices over the years and decades to come.”

Advanced sensor to unlock the secrets of the brain

17 April 2018:

CNBP researchers have announced the development of a state-of-the-art sensor that can for the first time detect signalling molecules, called cytokines, which operate in the living brain. Cytokines in the brain are secreted by glia cells that make up nearly 90% of all brain cells. Cytokines play a central role in controlling mood and cognition and may also contribute to a number of mental health disorders.

“What we’ve developed is the first sensor capable of monitoring the release of these cytokines in the brain,” says lead researcher Kaixin Zhang, a PhD candidate at the ARC Centre of Excellence for Nanoscale BioPhotonics (CNBP) at Macquarie University.

“Critically, there is mounting evidence that these glial-released cytokines play a central role in regulating a range of brain functions. In particular they are responsible for affecting mood, cognition and behaviour.”

“Our innovative new sensor has the potential to increase our knowledge not only of how the brain works, but may be able to shed light on conditions such as depression, stress, anxiety and even schizophrenia,” he says.

The sensor consists of a modified optical fibre which has had its surface treated with a capture protein. The protein reacts to the presence of cytokine molecules and is capable of monitoring local cytokine release in discrete and targeted parts of the brain.

Professor Ewa Goldys, CNBP Deputy Director, and a senior researcher on the project, notes that brain functionality is an extremely complex area where scientific knowledge is still limited.

“Our research in understanding cytokine secretion, neural circuits and how these two work together is essential to improving our understanding of the brain, in health and disease. Our sensor has opened a new window to the brain, but we still have far more to discover,” she says.

“The key benefit of our new sensor is that it enables the detection of cytokine release precisely as it happens, in living, naturally behaving animals, which is the key step on this discovery journey. To date, suitable tools have not been available to do this as the living brain is an incredibly difficult part of the body to access, and these cytokines are very difficult to measure.”

Published in the leading scientific journal ‘Brain, Behavior, and Immunity’, the cytokine sensor research was undertaken by an international team of scientists at the ARC Centre of Excellence for Nanoscale BioPhotonics (CNBP), Macquarie University, University of Colorado Boulder, Central China Normal University and The University of Adelaide.

“This is a really fantastic example of the work which we do at the CNBP, which is all about creating state-of-the-art sensing tools that can measure the inner workings of the living organism,” says Prof Goldys.

“It may be early days in this research but it will be fascinating to see where this cytokine detection takes us. It may prove to be a pivotal point in the understanding, and eventual diagnostic and clinical treatment, of a whole range of health conditions.”
