Researchers at the ARC Centre of Excellence for Nanoscale BioPhotonics (CNBP), Macquarie University, the University of Technology Sydney (UTS), Peking University and Shanghai Jiao-tong University have made a breakthrough in the development of practical super-resolution optical microscopy that will pave the way for the detailed study of live cells and organisms, on a scale 10 times smaller than can currently be achieved with conventional microscopy.
Reported in Nature, the international team of researchers has demonstrated that bright luminescent nanoparticles can be switched on and off using a low-power infrared laser beam, and used to achieve images with a super resolution of 28nm.
Professor Jim Piper (pictured), leader of the research team at Macquarie University and the CNBP sees these nanoparticles as having new unique properties. “These allow researchers to see well beyond normal limits of standard microscopes. It will let you see deeper and more clearly at the cellular and intra- cellular level—where proteins, antibodies and enzymes ultimately run the machinery of life.”
The research featured in BioPhotonics World.

Our researchers and collaborators have made a breakthrough in the development of practical super-resolution optical microscopy that will pave the way for the detailed study of live cells and organisms, on a scale 10 times smaller than can currently be achieved with conventional microscopy.
Reported in Nature, it was demonstrated that bright luminescent nanoparticles can be switched on and off using a low-power infrared laser beam, and used to achieve images with a super resolution of 28nm (about 1/36 the wavelength of light).

8 December 2015:
Prof Jim Piper, CNBP Macquarie University Node Leader has been awarded Honorary Life Membership of the Australian Optical Society (AOS) following the organisation’s annual general meeting, held in 2015.
The award recognizes Jim’s contribution to the society over many years. His signature was on the Memorandum of Association that established the AOS as an association in 1983. He took over the AOS presidency in 1984-1985, and was the recipient of the AOS W.H. (Beattie) Steel Medal – in 1997.
Also awarded life membership at the December 2015 meeting were Macquarie University’s Prof. Brian Orr and Prof. Ross McPhedran from the University of Sydney.
All continue to be involved with the AOS on an ongoing basis.
11 May 2015:
CNBP Director, Macquarie University Node, Prof Jim Piper has attended the ‘Enabling Technologies Technical Exchange Meeting 2015’, recently held in Arlington, Virginia.
The event, held under the auspices of the 2015 United States-Australia Joint Commission Meeting on Science and Technology, looks to enhance strategic scientific dialogue between the two countries as well as promote joint efforts in addressing complex problems facing the world today.
This year’s theme was ‘Enabling Technologies’ with Prof Piper giving two well received talks – ‘Supporting Structures for Australian Discovery Research’ and ‘Time-coded Luminescent Nanoparticles for High Contrast Detection of Specific (sub) Cellular Targets’.
4 December 2014: Congratulations
Congratulations to Professor Jim Piper who has been elected president of Science Technology Australia (STA).
Science & Technology Australia represents Australia’s scientists and technologists – promoting their views on a wide range of policy issues to government, industry and the community.
