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.

WHAT IS DIABETES? 

In each sort 1 and sort 2 diabetes, the body struggles to healthily keep its own blood sugar, or ‘glucose’, levels.

Victims have a high danger of heart illness, blindness, nerve injury, kidney injury, and fatigue.

To fight the situation diabetics need to incessantly measure their blood glucose ranges and inject a corresponding dose of the hormone insulin.

Insulin helps the physique to take glucose into tissue cells by opening up membrane channels. 

Sort 1 diabetes is an autoimmune illness that causes the insulin producing cells within the pancreas to be destroyed, preventing the body from with the ability to produce sufficient insulin to manage blood glucose levels. 

Sort 2 diabetes occurs when the physique fails to make use of insulin properly – recognized to scientists as insulin resistance – and could be brought on by obesity and a nasty food regimen. 

‘The Dermal Abyss creates a direct entry to the compartments in the body and displays internal metabolic processes in a shape of a tattoo,’ the MIT Media Lab researchers wrote in a blog post.

‘It might be used for purposes in constantly monitoring similar to medical diagnostics, quantified self, and knowledge encoding in the physique.’

It isn’t the first time a gaggle of MIT researchers have created a skin-based know-how.

Last yr scientists announced DuoSkin – momentary tattoos that may are delicate to the touch and can be used to regulate digital units like smartphones.

Using gold leaf, the short-term transfers can be utilized as contact delicate trackpads or to transmit info to a smartphone.

For instance, swiping left or proper on the tattoo might be used to scroll by means of an album of images.

The process makes use of gold leaf, like that utilized in baking or adorning picture frames, to create ‘three courses’ of system.

‘We consider that in the future, on-skin electronics will not be black-boxed and mystified,’ MIT researchers wrote on their website on the time.

‘As an alternative they’ll converge in the direction of the consumer friendliness, extensibility, and aesthetics of body decorations.’
