Diabetic Tattoos!?
March 25, 2009
Wow, this is impressive. Really very clever scientist types at Draper Laboratories have invented a diabetic tattoo that changes colour to indicate the state of the users blood sugar levels!
The ink is injected subcutaneously and changes colour in response to glucose. Each ink nano particle is made of three parts: a glucose detecting molecule, a dye molecule and a molecule mimicking glucose.
As they move around inside the nano particle, the glucose detecting molecule either latches on to the mimicking molecule or real glucose, and changes the colour of the dye accordingly. So when more glucose is present in the blood, the colour changes as the detecting molecules all change their colour. Very cool.
Hmm.. does this mean I have to change the SimpleGlucose interface to accept colours now, instead of traditional numeric readings?
