An ‘Institute for Photonics and Advanced Sensing’ (IPAS) pilot grant worth $6,000 has been awarded to CNBP researchers Dr Jingxian Yu (project lead – pictured left) and Dr Peipei Jia.
The grant will allow investigation into “double remote electrochemical addressing and optical readout of electrochemiluminescence at the nanopatterned tip of an optical fiber for the detection of biological species.”
The project has great potential to provide a versatile sensing platform for chemical sensing and medical diagnostics.
The proposed work will also bring chemists and physicists together to work in this trans-disciplinary area, with the possibility of promoting further collaborations between biological and medical scientists within IPAS and the CNBP.

CNBP’s Dr Philipp Reineck has given a talk at the Aimé-Cotton Laboratory (LAC), Paris, which he is currently visiting as a guest researcher.
The laboratory is a joint research unit of the National Center for Scientific Research (CNRS), the University of Paris-Sud and the Ecole Normale Supérieure de Cachan.
Philipp’s talk consisted of an overview of CNBP science and more specifically, focused on Centre projects across the nano-diamond sensing and bio-imaging space.

Dr Sanam Mustafa, CNBP Researcher, presented an invited keynote lecture at the Royal Australasian College of Surgeons 86th Annual Scientific Congress, 10 May 2017.
Her talk was titled, “Recent developments in post-operative pain management – should we be worried?” and discussed the implications of using morphine for neuropathic pain.
The Congress took place at the Adelaide Convention Centre, Adelaide, South Australia.

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.

Researchers from CNBP and The Institute of Photonic Technology (lead author Stephen Warren-Smith pictured), have just had a paper published on tuning third harmonic light generated within exposed-core fibres.
Journal: Optics Letters.
Publication title: Nanofilm-induced spectral tuning of third harmonic generation.
Authors: Stephen C. Warren-Smith, Mario Chemnitz, Henrik Schneidewind, Roman Kostecki, Heike Ebendorff-Heidepriem, Tanya M. Monro and Markus A. Schmidt.
Abstract: Intermodal third-harmonic generation using waveguides is an effective frequency conversion process due to the combination of long interaction lengths and strong modal confinement. Here we introduce the concept of tuning the third harmonic phase-matching condition via the use of dielectric nanofilms located on an open waveguide core. We experimentally demonstrate that tantalum oxide nanofilms coated onto the core of an exposed core fiber allow tuning the third harmonic wavelength over 30 nm, as confirmed by qualitative simulations. Due to its generic character, the presented tuning scheme can be applied to any form of exposed core waveguide and will find applications in fields including microscopy, biosensing, and quantum optics.
The paper is accessible online.

CNBP Chief Investigator, A/Prof Jeremy Thompson has received $7000 in travel support from the Global Connections Fund Priming Grants initiative.
The grant will fund travel to the USA to visit cattle IVF units with the aim of learning how they have made a successful business of in vitro produced embryos, and where it applies best in their (beef) breeding and genetic selection operations.
While there, A/Prof Thompson will be sharing knowledge and experiences and seeing if there are potential collaborative opportunities.

A new publication from CNBP researchers (lead author Dr Ivan Maksymov pictured) demonstrates a new scheme for synthesis of optical spectra from nonlinear ultrasound harmonics using a hybrid liquid-state and nanoplasmonic device compatible with fibre-optic technology.
The work has just been reported in the journal ‘Optics Express’ and is accessible online.
Journal: Optics Express.
Title: Synthesis of discrete phase-coherent optical spectra from nonlinear ultrasound.
Authors: Ivan S. Maksymov and Andrew D. Greentree.
Abstract: Nonlinear acoustic interactions in liquids are effectively stronger than nonlinear optical interactions in solids. Thus, harnessing these interactions will offer new possibilities in the design of ultra-compact nonlinear photonic devices. We theoretically demonstrate a new scheme for synthesis of optical spectra from nonlinear ultrasound harmonics using a hybrid liquid-state and nanoplasmonic device compatible with fibre-optic technology. The synthesised spectra consist of a set of equally spaced optical Brillouin light scattering modes having a well-defined phase relationship between each other. We suggest that these spectra may be employed as optical frequency combs whose spectral composition may be tuned by controlling the nonlinear acoustic interactions.
