13 August 2017:
Over 400 interested members of the public, including prospective students, dropped by the CNBP laboratories as a part of RMIT University’s annual Open Day event, Sunday 13th August, 2017.
The Centre had two optics laboratories open and both were fully staffed by researchers eager to share their knowledge and enthusiasm for science.
In the first laboratory, an Olympus wide field microscope was on display with a live-cell incubation chamber and a daphnia (water flea), with brightfield and fluorescence videos.
In the other, a cryogenic confocal microscope was on show, which is able to look at the optical properties of nanomaterials, down to temperatures of 4K (which is -269 deg C).
According to CNBP node leader at RMIT, A/Prof Brant Gibson, the day was a great success.
“We saw a large, interested and engaged crowd who really wanted to find out more about our research and activity, and were curious as to how nanoscale biophotonics was going to impact society over coming years.”
There was also a large number of prospective students who visited and talked with CNBP team members. They had a wonderfully diverse range of interests ranging across the physics, chemistry, biology, IT and engineering disciplines.”
“It was fantastic to see the next generation of excited young scientist!”

Around fifty high performing Year 10 to Year 12 students from Australia and New Zealand came to RMIT on the 11th of July to listen to CNBP Chief Investigator Prof Andy Greentree present a talk titled “Colour: the palette of the mind.”
The talk was a part of the Youth ANZAAS visit to RMIT University. Youth ANZAAS 2017 is organised by the Australian and New Zealand Association for the Advancement of Science and the Royal Society of New Zealand. It is is an annual residential international forum for science students still at school.
An abstract of Prof Greentree’s talk follows:
Colour is a complicated phenomenon! For most of us, most of the information we receive about the world comes from light, and that light is encoded by colour. This talk will explore colour. From the physics of light, to how we detect colour information, to the psychophysics of how our brain understands those signals to make sense of the world.

The RMIT School of Science Research Day was held on July 10th, with several members of the RMIT Node presenting CNBP research.
Postgraduate students Daniel Stavrevski, Marco Capelli and Josef Worboys participated in the 3 Minute Thesis competition: Josef Worboys was awarded the winning prize for his work related to ‘quantum correlations’, and will go on to the University level competition.
The day’s program was concluded with a poster session including posters from CNBP’s Philipp Reineck, Emma Wilson, Nafisa Zohora, Marco Capelli and Ashleigh Heffernan.

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‘.

Researchers from CNBP’s RMIT University node (lead author CNBP PhD student Marco Capelli pictured), have had a paper published in the journal ‘Nanoscale’.
The researchers report an enhancement of the nitrogen-vacancy (NV) quantum yield by up to 7% in bulk diamond caused by an external magnetic field.
The paper is accessible online.
Publication title: Magnetic field-induced enhancement of the nitrogen-vacancy fluorescence quantum yield .
Authors: M. Capelli, P. Reineck, D. W. M. Lau, A. Orth, J. Jeske, M. W. Doherty, T. Ohshima, A. D. Greentree and B. C. Gibson.
Abstract: The nitrogen-vacancy (NV) centre in diamond is a unique optical defect that is used in many applications today and methods to enhance its fluorescence brightness are highly sought after. We observed experimentally an enhancement of the NV quantum yield by up to 7% in bulk diamond caused by an external magnetic field relative to the field-free case. This observation is rationalised phenomenologically in terms of a magnetic field dependence of the NV excited state triplet-to-singlet transition rate. The theoretical model is in good qualitative agreement with the experimental results at low excitation intensities. Our results significantly contribute to our fundamental understanding of the photophysical properties of the NV defect in diamond.

CNBP Research Fellow Dr Philipp Reineck has been selected as a delegate for the ‘Theo Murphy High Flyers Think Tank’, a national group established by The Australian Academy of Science.
The Think Tank will bring together early and mid-career researchers exploring nutrition science in an interdisciplinary fashion.
Findings will contribute to the development of a long term strategic planning process for nutrition research in Australia.
Further information on the Think Tank is available online.

CNBP was well represented at the 11th International Conference on New Diamond and Nano Carbons, held in Cairns, Australia, 28th May – June 1, 2017.
CNBP Chief Investigator A/Prof Brant Gibson was Co-chair of the conference (pictured) with CNBP researcher Dr Philipp Reineck a contributing speaker, presenting on ‘Bright and photostable nitrogen‐vacancy fluorescence from unprocessed detonation nanodiamonds’.
Also providing a contributing talk was CNBP’s Dr Lindsay Parker, ‘Applications of fluorescent nanodiamonds in cellular molecular tracing.’
Additionally, CNBP’s Andrew Greentree, Ivan Maksymov, Daniel Drumm, Ashleigh Heffernan, Marco Capelli, Nicole Cordina and Emma Wilson gave poster presentations and Brooke Bacon and Desmond Lau provided administrative and technical support respectively.
The conference spanned research topics from fundamental physical and chemical concepts to applied technologically driven applications with carbon based materials. This including single crystal diamond, nanodiamonds, carbon nanotubes, graphene and other carbon nanostructures.
10 May 2017:
Dr Philipp Reineck, CNBP Research Fellow, has given an invited talk at the ENM Nanoparticle meeting in San Sebastian in Spain, 10 May 2017.
His talk was titled, ‘Near-IR fluorescent nanomaterials for bioimaging and sensing applications.’ Dr Reineck also chaired a workshop/session on nanoparticles for optical bioimaging.
Further information on the conference can be found online.

Dr Philipp Reineck, CNBP Researcher at RMIT University has won best poster award at the 5th International Conference on Biophotonics (ICOB 2017), 30 April – 1 May 2017, Fremantle, Western Australia.
The poster reported on recent advances in the development and use of near-infrared fluorescent nanomaterials for biomedical imaging and sensing applications.
Dr Reineck was originally invited to give a short oral presentation about his poster, which was then selected as a ‘hot poster’ before the conference commenced. It then won ‘best poster’ resulting in a cash prize of $600 AUD.
During his short talk at ICOB, Philipp also discussed the potential of NIR fluorescent materials for wearables – for example, a watch that interrogates particles in bloodstream via near infrared light, to determine glucose levels.
Information about the ICOB conference is available online.
5 April 2017:
Dr Antony Orth, CNBP Research Fellow has attended the ‘OSA Biophotonics Congress: Biomedical Optics’ in San Diego, 2-5 April 2017.
During the event he undertook two presentations: ‘Towards Dictionary-Enhanced Microscopy’ and ‘Bleaching-Assisted Multichannel Microscopy’.
