Measuring blood sugar with light

A team of German researchers has devised a novel, non-invasive way to make monitoring easier. Using infrared laser light applied on top of the skin, they measure sugar levels in the fluid in and under skin cells to read blood sugar levels. They describe their method in the current edition of Review of Scientific Instruments, which is produced by AIP Publishing.

"This opens the fantastic possibility that diabetes patients might be able to measure their glucose level without pricking and without test strips," said lead researcher, Werner Mäntele, Ph.D. of Frankfurt's Institut für Biophysik, Johann Wolfgang Goethe-Universität.
