New smartphone technique developed for measuring blood glucose levels by researchers

The National Institute of Standards and Technology (NIST) in the United States has announced a new technique that uses a magnetometer in cellphones to accurately measure blood glucose levels. This technology takes advantage of the magnetometer that is typically used for navigation purposes but has other potential applications.

In a proof-of-concept study, researchers attached a small well containing a solution, instead of blood, and a strip of hydrogel to a cellphone. The hydrogel, which is porous and reacts to glucose levels by expanding and contracting, was engineered to detect changes in pH levels as well. Changes in pH can indicate different disorders. The movement of magnetic particles within the hydrogel caused corresponding changes in the strength of the magnetic field detected by the magnetometer in the cell phone.

The researchers claim that this method has the potential to measure extremely small concentrations of glucose, although such sensitivity may not be necessary for at-home glucose monitoring. This technology could also be used to test for glucose in saliva, which has lower sugar concentrations than blood. The NIST team stated that smart hydrogels are cost-effective and relatively simple to create, making them viable for inexpensive test kits that can be connected to a smartphone app for measuring blood glucose levels.

The results of this research have been published in the journal Nature Communications. This innovative use of a smartphone’s magnetometer could provide a low-cost alternative for blood glucose monitoring compared to existing options.

This novel technique developed by NIST utilizes the magnetometer found on most modern cellphones to accurately measure blood glucose levels with high accuracy. Researchers believe that this method could also be expanded to detect various molecules and biomarkers in blood.
