Measuring blood sugar with light

One of the keys to healthful living with Type 1 and Type 2 diabetes is monitoring blood glucose (sugar) levels to ensure they remain at stable levels. People can easily and reliably do this at home using electronic devices that read sugar levels in a tiny drop of blood.
Now 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.
‘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 M
