Colour-changing tattoo ink could help people with diabetes

Posted on

Researchers have developed a biosensing tattoo ink that reacts to sugar within the blood to help diabetics management their circumstances.

The color-changing ink turns the body’s surface into an ‘interactive display’ to alert diabetics when their blood sugar is just too low or high.

When blood sugar goes up, the glucose sensing ink modifications from blue to brown in real-time, a color change that reverses when blood sugar drops.

HOW IT WORKS

The ink senses modifications to the physique’s interstitial fluid – the liquid that surrounds tissue cells in the body.

When the glucose sensing tattoo ink senses a change in blood sugar levels, it modifications color.

If blood sugar is low, it modifications from brown to blue, and if high, it modifications from blue to brown.

The tattoos might at some point act as a non-invasive technique for diabetics to regulate their condition.

The researchers also developed inks that sense salt and pH levels.

The ink acts as a biosensor that reads interstitial fluids – the liquids that surround tissue cells in the physique.

Other biosensing tattoo inks developed by the group, from the Massachusetts Institute of Know-how, monitor the physique’s salt and pH levels.

The salt sensing inks, which monitor the mineral by measuring sodium levels, fluoresce beneath UV mild, shifting to an intense green when high salt ranges are detected.

The pH sensing inks reply to alkalinity and alter from pink to purple because it increases.

The researchers recommend that their tattoo inks, which they are saying are presently simply at the ‘proof of idea’ stage, might supply new ways of monitoring the physique.

For diabetics, the glucose sensing ink supplies a solution to monitor blood sugar levels with out having to prick the pores and skin and take a blood pattern every few hours.

One biosensing tattoo might tell a diabetic what dose of insulin they wanted to re-balance their blood sugar at any time.
