Graphene-Based Sensor Could Improve Evaluation, Diag-

nosis andTreatment of Asthma

Rutgers University-New Brunswick scien-

tists have created a graphene-based sen-

sor that could lead to earlier detection of

looming asthma attacks and improve the

management of asthma and other respira-

tory diseases, preventing hospitalizations

and deaths.

How Diamond Sensors Are Set to Revolutionize Medical

Diagnostics

The human body pulses with electric fields that are caused by the movement of charge

through nerves and across muscle tissue. But the same processes also produce mag-

netic fields, and these have the potential to be just as useful in diagnosing disease, per-

haps even more so. In particular, magnetic sensors do not need to touch the skin to do

their work. The body’s magnetic field is tiny, and detecting it requires hugely sensitive

sensors.The only commercially available gadgets that can do this job are superconduct-

ing quantum interference devices, or SQUIDs, which can measure changes in magnetic

fields measured in femtoTesla (10-15).These need to be cooled to the temperature of

liquid helium, and the measurements made in screened rooms that are shielded from

external magnetic fields. Matthew Dale and Gavin Morley at the University ofWarwick

in the U.K. say that diamond sensors are poised to revolutionize the way physicians use

magnetic field measurements in diagnostic medicine.They map out the state of the art in

this area and say that the business opportunity is significant.
