Thought you might find this interesting. Some sort of non-invasive glucose

monitoring system is needed for diabetics, especially when they are in a

hospital environment, particularly ICU and when undergoing surgery or

surgery-like procedures.

Future Cures - A Decade Away

Glucose-monitoring tattoos

You thought tattoos were just for punk rockers and Harley-son fans?

Think again. , Ph.D., associate professor of pharmaceutical

sciences at Northeastern University in Boston, has developed a tattoo that

can monitor your blood sugar without constant needle pricks-a huge

advancement for the 26 million Americans with diabetes.

The miniature tattoo-only a few millimeters in size-is made of nano-sensors:

tiny polymer beads containing a yellow-orange dye that lights up when

glucose levels are high and darkens as glucose levels drop. While

traditional tattoos permanently stain the deeper layers of the skin, the

diabetes tattoo is applied to more superficial skin layers, so its

application is less painful and it wears off over time.

" The plan is to have tattoos applied once a week, " says . Patients will

use a handheld device to scan the tattoo several times a day for color

changes to guide their insulin use.

's team has tracked glucose levels in tattooed mice with diabetes,

confirming these results with blood tests they took at the same time. If

upcoming clinical trials in humans pan out, the tattoos could be on the

market in a decade.
