Researchers repurpose cellphone magnetometer to measure glucose levels accurately, offering potential breakthrough in diabetes management.
cellphonesThe new system enables cell phones to measure the levels of glucose, a marker for diabetes, with excellent precision.The magnetometer combined with magnetic materials would alter its structure in response to biological or environmental stimuli. This could contribute to monitoring or diagnosing disease.In their proof-of-concept investigation, scientists attached a miniature well containing the solution under examination and a strip of hydrogel to a phone.
The hydrogels’ expansion and contraction causes the magnetic particles to migrate in different directions relative to the magnetometer on the cell phone.glucose The team layered single layers of two distinct hydrogels in their studies; each hydrogel responded to pH or glucose by contracting and expanding at a different rate.
That enhancement might be very beneficial. For example, detecting histamines would normally involve a 24-hour urine collection and a complex laboratory study.
