Researchers Using Bluetooth-enabled Devices to Detect Fermentation Process

Electrochemical reactions that occur in processes like ethanolic fermentation embrace the transformation of sugars into alcohol and carbon dioxide. Similar processes happen when the human body breaks down meals, medicine, or other compounds.

Monitoring these metabolic processes helps in testing, studying, and combating illness; however, due to the small portions of liquids involved, they’re troublesome to review with regular equipment.

Miniaturizing gadgets with environmental sensing capabilities offers promise for better testing of fermentation and other biochemical processes. The flexibility to operate the gadgets wirelessly over long periods of time increases their effectiveness.

In a paper revealed this week in Review of Scientific Devices, a miniaturized potentiostat, which controls voltage between electrodes, proved able to quantifying molecules using voltammetric and chronoamperometric strategies with the 98% accuracy. The wireless machine is compatible with most 3-electrode biosensors and can transmit its measurements through Bluetooth for 100 meters.

The potentiostat was tested to substantiate its performance under fixed-resistance and quantify the current detection limits and noise in the system, in addition to its accuracy and response time.

Experiments confirmed a current detection limit of 180 nano amperes and a plus or minus 2% standard deviation in cyclic voltammetry measurement. In addition, they performed an experiment involving six different concentrations of glucose, utilizing a chronoamperometry technique.
