A New Method for More Sensitive Electrochemical Sensors

Graphene and related materials hold promise for the future of electrochemical sensors — detectors that measure the concentration of oxygen, toxic gases, and other substances — but many applications require greater sensitivity at lower detection ranges than scientists have been able to achieve.

A Northwestern University research team and partners in India have recently developed a new method for amplifying signals in graphene oxide-based electrochemical sensors through a process called “magneto-electrochemical immunoassay.” The findings could open up a new class of technologies with applications in medicine, chemistry, and engineering.
