Nanoengineers at University of California Discovered High-Tech Ink to Detect Blood Glucose

Published By : 04 Mar 2015 | Published By : QYRESEARCH

Nano-engineers at the University of California, San Diego, developed a new tool that is nothing more than an ordinary ball-point pen and filled it with a special kind of bio ink. The bio-ink reacts when it comes in contact with a variety of chemicals including glucose. The ink could accurately detect the level of blood glucose by simply drawing on the skin. The discovery by a group of nano-engineers is believed to have ushered a new era when anyone could build sensors at any point of time including patients in the comfort of their homes, soldiers while they are away on field, or physicians when they are in their clinic. 

The highly advanced bio-inks that the team of nano-engineers from the University of Calfornia developed, reacts with many chemicals, including glucose. The team filled standard sized ballpoint pens with the high-tech ink that was able to measure the glucose level directly on skin. The sensors were also able to detect the level of pollution on leaves. 

It wasn’t only the skin and leaves where the pens could be used. The researchers envision using the sensors to draw directly on smart phones for inexpensive and personalized monitoring or on even on the external walls of buildings to monitor the level of toxic gas pollutants present in the atmosphere. In fact they envision the use of the sensors in the battlefields as well to detect nerve agents and explosives. The team of nano-engineers who discovered the high tech ink was led by Joseph Wang. They published their discovery in the Advanced Healthcare Materials. 

The biggest challenge the team faced was to make the ink from biochemicals and chemicals that would not be harmful for humans or plants.
