Noninvasive imaging could replace finger pricks for measuring blood glucose

I've worked in this business. Non-invasive blood glucose monitoring has been a holy grail of analytical science for 50+ years. I've known two people who have gone bankrupt trying to do it.

The spectrum contains signatures of hundreds of compounds. All of the variation has to be accounted for. It's actually a ridiculously hard problem.

Still, holy grails being what they are, I'm still excited when I see that someone is giving it another chance.

Wasn't Apple working on this?

Having a diabetic father, who has been using pricks for the last 20 years. This would be really amazing to see this work. And I hope this can provide 24 hour glucose monitoring to see the fluctuations.
