Optical Sensor for Vitamin B-12 Deficiency in Blood
December 13, 2016 | Terry Sharrer
“University of Adelaide researchers have developed a world-first optical sensor that can detect vitamin B12 in diluted human blood — a first step towards a low-cost, portable, broadscale vitamin B12 deficiency test. Vitamin B12 deficiency is associated with an increased risk of dementia and Alzheimer’s disease.” The test relies on Raman spectroscopy to produce an optical “fingerprint” of vitamin B12. MORE
