IPAS best papers competition

cnbplogosquare129 January 2016:

CNBP researchers featured prominently in the recent ‘Institute for Photonics and Advanced Sensing (IPAS) Best Papers’ competition.

The awards, presented in January 2016,  aim to showcase the quality and impact of the research being conducted by IPAS members.

Winners for the best ECR led Paper were Abel Santos, Agnieszka Zuber and CNBP Research Fellow Xiaozhou (Michelle) Zhang.

The best PhD Student Led Paper Awards went to CNBP student Malcolm Purdey, Parul Mittal and Tess Reynolds.

The Best Transdisciplinary Paper with a Strong Medical/Animal Science Element went to CNBP senior researcher Melanie McDowall.

Full details on the awards, all of the winners and their papers can be found at the IPAS web site.

Counting cancer-busting oxygen molecules

Ewa Goldys Low Res Edit 015928 January 2016:

CNBP researchers have established that a therapeutic dose of X-rays, in combination with CeF3 nanoparticles, can produce enough singlet oxygen molecules to be effective in photodynamic therapy. The finding has been reported in the journal Scientific Reports, published online today.

The complete research paper is available for download, from the Nature Publishing Group web site. A CNBP media release has also been produced.

New CNBP student at Macquarie University

Manoj_3a20 January 2016:

CNBP welcomes its newest student Manoj Kale, who will be undertaking a two year Master of Research program at Macquarie University.

Manoj will be supervised by CNBP Deputy Director Prof. Ewa Goldys as well as joining her research group – the title of his research thesis, “Fluorescence in Biomedicine.”

Prior to enrolling at Macquarie University, Manoj completed a Bachelor of Engineering in Electronics and Telecommunication from the Government College of Engineering, Aurangabad, India.

He then undertook a Master of Technology in Nanotechnology at the Vellore Institute of Technology, Vellore, India, achieving expertise in nanomaterial synthesis and characterization techniques.

His career goal is to join a research-oriented organisation and to continue to further his research in novel nanomaterials synthesis and application in the field of Biophysics and Biophotonics.

Welcome to the team Manoj!

 

Supporting Science Experience 2016

Varun Sreenivasan_web15 January 2016:

CNBP researchers  Varun Sreenivasan and Denitza Denkova extended their outreach skills in support of the ConocoPhillips Science Experience program that took place at Macquarie University 13-15th January 2016.

The national program, focused on  Year 9 and 10 students who have an interest in science, is rolled-out across universities and tertiary institutions across Australia. Students who attend are provided with the opportunity to engage in a wide range of fascinating science activities under the guidance of scientists who love their work.

As a part of this program, Varun and Denitza contributed to the ‘Physics and Chemistry Magic Show’ which ran for an hour at Macquarie University’s Science Faculty. Demonstrated were concepts such as the ‘Stroboscopic effect’, the physics behind a ‘singing wineglass’ and the fun that can be had with Sulfur Hexafluoride.

“Through this event, we were able to share our excitement of science with youngsters, hopefully motivating them to do science as they grow up,”said Varun.

“We also improved our presentations and quick problem solving skills too!”

 

Ground breaking hybrid nanocrystal work

Dayong Jin  Low Res Edit 00968 January 2016:

The top ranking journal ‘Nature Communications’ has published the latest ground breaking research from CNBP scientists with a paper titled, ‘Three-dimensional controlled growth of monodisperse sub-50 nm heterogeneous nanocrystals’.

The paper details the creation of  a library of over 800 newly shaped nanocrystals formed from ordered atom clusters over a period of three years. The different shaped or ‘hybrid’ nanocrystals will act as new tools impacting the areas of bio-imaging, diagnostics and nano-medicine.

According to CNBP Chief Investigator, Prof Dayong Jin, the work could form new solutions to getting around the body’s immune system response in the targeted treatment of cancerous cells, which causes both the healthy and diseased cells to die.

The full text of the paper is available online from the Nature Communicatons web site.

 

Coverage: New sensor to aid IVF

Malcolm Purdey Low Res Edit 00756 January, 2016:

The tricky process of monitoring early-stage embryos during the IVF process could become much easier with the development of a new fibre-optic sensor that can measure concurrently, hydrogen peroxide and pH (acidity-alkalinity concentrations) in solution.

The sensor, the first of its kind, was reported in the research journal ‘Sensors’ and consists of a single optical fibre, the tip of which has been functionalised with a reactive fluorescent coating.

Lead author on the paper, CNBP researcher Malcolm Purdey was interviewed by ABC News Radio and featured in other media including the Daily Examiner and BioOptics World.

Acoustically-Driven Trion & Exciton Modulation in Piezoelectric 2D MoS2

Brant Gibson Low Res4 January 2016:

CNBP’s A/Prof. Brant Gibson (CNBP CI) and Dr. Desmond Lau (CNBP Technical Officer) featured as co-authors in a recently published paper in the journal ‘Nano Letters’.

The paper exploited the recent discovery of the piezoelectricity in odd-numbered layers of two-dimensional molybdenum disulfide (MoS2), to show the possibility of reversibly tuning the photoluminescence of single and odd-numbered multilayered MoS2 using high frequency sound wave coupling.

As such, the work reveals several key fundamentals governing acousto-optic properties of odd-layered MoS2 that can be implemented in future optical and electronic systems.

Additional information can be found in the Journal ‘Nano Letters’ online.
