“This system is versatile and can be easily modified to detect other substances for use in healthcare, environmental and defense applications,” Wang said.
The UCSD-developed system can store a lot of data over long periods of time. The 3D printed parts are inexpensive to make, but the pellets can cost a little more than test strips in traditional glucose monitoring kits.
GlucPhone is currently in the proof-of-concept stage and the researcher plan to test the system on actual blood samples and minimize the dozen drops of samples needed for each test. They also hope to further develop the app to send alerts to the user reminding them to check their blood sugar.
