Novel 3D-printed glucose biosensors developed

IANS  |  New York 

Researchers have created a 3D-printed biosensor for use in wearable monitors that may lead to improved monitors for people suffering from

According to the researchers, people with most commonly monitor their with meters that require constant finger pricking. Continuous glucose systems are an alternative, but they are not cost effective.

"Our 3D-printed glucose sensor will be used as wearable sensor for replacing painful finger pricking. Since this is a non-invasive, needleless technique for glucose monitoring, it will be easier for children's glucose monitoring," said from the School of Mechanical and Materials Engineering, in the US.

The team has been working to develop wearable, flexible that can conform to patients' skin and monitor the glucose in body fluids, such as in sweat.

To build such sensors, manufacturers have used traditional strategies, such as or While these methods work, they have several drawbacks, including requiring the use of and expensive cleanroom processing, the team said.

For the study, published in the journal, 'Analytica Chimica Acta', the researchers used a method called direct-ink-writing (DIW), that involves "inks" out of nozzles to create intricate and precise designs at tiny scales.

The team printed a nanoscale material that is electrically conductive to create flexible electrodes.

The finding showed that their 3D-printed sensors did better at picking up glucose signals than the traditionally produced electrodes.

"can enable of tailored specifically to individual patients" said Arda Gozen from the varsity.

For large-scale use, the printed will need to be integrated with electronic components on a wearable platform, the said.

But manufacturers could use the same 3D-printer nozzles used for printing the sensors to print and other components of a wearable medical device, helping to consolidate processes and reduce costs even more, he added.

The research team is now working to integrate the sensors into a packaged system that can be used as a for long-term glucose
