Research from the ARC Centre of Excellence for Nanoscale BioPhotonics (CNBP) could enable the tricky process of monitoring early-stage embryos during the IVF process to become much easier. Researchers have developed a new fibre-optic sensor that can measure concurrently, hydrogen peroxide and pH (acidity-alkalinity concentrations) in solution.

Lead author on the paper and CNBP Research Associate, Malcolm Purdey, believes the sensor has the potential to be used across a broad range of biological applications, but that it is particularly well suited to the IVF industry.

“Unregulated production of hydrogen peroxide by an embryo, as well as fluctuating levels of pH, can indicate embryonic stress, impacting embryo development,” said Mr Purdey.

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.
