Instead of putting up with a mild pin-prick whenever your blood sugar levels need testing, Japanese scientists have invented a little implant that glows when the levels change. No pain, and a free glowstick for raves — high five, science!
Diabetics may have yet another tool in their blood-sugar management arsenal - an implantable, fluorescent blood-sugar monitor. It involves small hydrogel beads that vary the intensity of emitted light depending on glucose concentration. They're called Life Beans.
For the first time, scientists have successfully implanted a biofuel cell that generates power from glucose inside a body - an everlasting battery you could theoretically recharge by eating a Snickers bar.
Diabetics are saddled with the unenviable task of checking their blood sugar levels constantly. But a new non-invasive technology lets diabetics keep tabs on their glucose levels with contact lenses that change colours as their blood sugar rises and falls.
