Novel optical sensor developed for vitamin B12 deficiency test

Researchers from the University of Adelaide (Adelaide, Australia) have developed a low-cost, portable vitamin B12 test that has demonstrated the capacity to detect vitamin B12 in diluted human blood, and which could be utilized to monitor high risk individuals for dementia and Alzheimer’s disease, enabling early intervention. The study, a collaborative effort comprising teams from the ARC Centre of Excellence for Nanoscale BioPhotonics, the Institute for Photonics and Advanced Sensing and the Schools of Physical Sciences and Medicine at the University of Adelaide, was recently presented at the inaugural SPIE BioPhotonics Australasia conference (Adelaide, Australia, 16–19 October 2016).
