New smartphone technique developed for measuring blood glucose levels by researchers

The National Institute of Standards and Technology (NIST) in the US has announced a new technique that employs a magnetometer in cellphones to accurately measure blood glucose levels. This technology takes advantage of the magnetometer that is commonly found in most modern cell phones, which is typically used for navigation purposes but has other potential applications.

Researchers at NIST have successfully demonstrated this method in a proof-of-concept study by attaching a small well containing a solution and a strip of hydrogel to a cellphone. The hydrogel, a porous material that swells when placed in water, was engineered to react to glucose levels and pH levels by expanding and contracting. Changes in pH levels can indicate different disorders. The movement of magnetic particles within the hydrogel in response to changes in glucose levels 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 ability to measure extremely small concentrations of glucose, although such sensitivity may not be necessary for at-home glucose monitoring. This technology could potentially enable testing for glucose in saliva, which has lower sugar concentrations. The NIST team stated that smart hydrogels used in this study 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 has the potential to provide an affordable alternative for blood glucose monitoring compared to existing options.
