Researcher from Northwestern University developed a new way to amplify signals in hybrid graphene oxide and CNT electrochemical sensors. They use a process called Magneto-Electrochemical Immunoassay to achieve that.

The researchers designed the new hybrid material to correlate the available metal ions with analyte concentration. They used magnetic particles encapsulated in inert coating of silicon dioxide which were later coated with gold (gold is chemically inert and bio-compatible). This process is efficient, fast and cost-effective.

This hybrid CNT-GO material can be used to make a sensitive and fast enviornmental pollutant or toxic sensor.
