Georgios Tsmininis visits CUL (Sun Tong) – Jan 2015

Visit date: 29th January 2015

Persons involved: Georgios Tsiminis, Tong Sun, Stephen Wren, Matthias Fabian

Overview: I had a very fruitful visit and we discussed setting a collaborative research project using a PhD student that they will advertise for to build on the mutual strengths of City and the Centre. Their interest is in developing a fibre sensors for glucose monitoring, based on their molecular imprint polymers, but they would very much like input and help on surface characterisation, establishing the quality and uniformity of the layers they put down in making their sensor. In addition, novel fibre structures, as well as access to clinical/animal testing capabilities for testing are on their list of things they could get from this collaboration. I was also glad to see that they have great experience in producing fibre sensors that are already being tested by industry partners and this is a strength of theirs we would greatly benefit from.

Dr Georgios Tsiminis visits Oxford University

“Taking a closer look at vitamin B12”, delivered by CNBP researcher Dr Georgios Tsiminis and  co-author Dr Joanna Brooks from the ARC Centre for Research on Ageing, Health and Wellbeing at the Australian National University.

The talk gave an overview on the potential for using Raman spectroscopy as a minimally invasive tool to measure and track vitamin B12 levels in humans. Vitamin B12 deficiency has been identified as a potential modifiable risk factor for dementia and Alzheimer’s disease in later life and is also the mechanism through which pernicious anaemia affects humans (vitamin B12 does not get absorbed through food due to lack of intrinsic factor). Current techniques for measuring vitamin B12 in humans, such as microbial growth and ELISAs, are both resource- and time-consuming, resulting in the general population not being regularly tested for vitamin B12 deficiency. Our aim is to produce a portable device that can measure vitamin B12 and its associated chemical compounds in a reproducible, reliable, fast and minimally-invasive manor. In this talk we explained the basic principles of Raman spectroscopy and showed some initial results that generated great interest at Oxford, who have asked us to keep them up to date with future developments on our work.

Undergraduate students take on a CNBP summer project

2015 summer student YuanJanuary 2015 – Summer student at Adelaide Node

Working with Dr Jinxian Yu and the recognise theme; Ms Yuan Yeoh has spent 6 weeks as a University of Adelaide summer research student.  It has been a pleasure to participate in a summer research project. This has given me an opportunity to learn, as well as to polish my lab skills. I feel happy to utilise the scientific knowledge into real-life applications. A summary of her project is described below.

Synthesis of Azobenzene as a Photo-inducible Molecular Switch

Azobenzene changes configuration (cis & trans) when illuminated with light of particular wavelength. This molecular switch can be incorporated into functional molecules, such as proteins, sensors, electronic devices, etc. Thus, by controlling the configuration of the switch, the electron transfer in functional molecules can be fine tuned.

Book Chapter: the Use of Nanotechnology in Pregnancy

25 January Achini Vidanapathirana Low Res Edit 01162015:

This book chapter by CNBP researcher Dr Achini Vidnapathirana examines  ‘the applications of nanotechnology during pregnancy (current, research, and potential applications), the unique pregnancy-related characteristics that relate in the application of nanoscale materials, and the concerns on maternal/fetal well-being.’
