New paper in ‘Nanoscale’

Low Res Edit 01065 December 2016:

A new publication from CNBP researchers (lead author Philipp Reineck pictured) demonstrates bright and photostable fluorescence from nitrogen-vacancy centers in unprocessed nanodiamond particle aggregates. The work has just been reported in the journal ‘Nanoscale’ and is accessible online.

Abstract: Bright and photostable fluorescence from nitrogen-vacancy (NV) centers is demonstrated in unprocessed detonation nanodiamond particle aggregates. The optical properties of these particles is analyzed using confocal fluorescence microscopy and spectroscopy, time resolved fluorescence decay measurements, and optically detected magnetic resonance experiments. Two particle populations with distinct optical properties are identified and compared to high-pressure high-temperature (HPHT) fluorescent
nanodiamonds. We find that the brightness of one detonation nanodiamond particle population is on the same order as that of highly processed fluorescent 100 nm HPHT nanodiamonds. Our results may open the path to a simple and up-scalable route for
the production of fluorescent NV nanodiamonds for use in bioimaging applications.

Director speaks at joint meeting

Professor Mark Hutchinson (Director, CNBP) was invited to speak at the joint Australian Physiological Society (AuPS) and Australian Society for Biophysics (ASB) meeting held in Adelaide on 5 December 2016.

He participated in the symposium “Thinking Small: Seeing Biological Processes with Nanotechnology and Photonics”.

His talk was titled, “Using Light to Measure the Previously Unmeasurable Within the Central Nervous System.”
