Miniaturized Reverse Electrodialysis-Powered Biosensor Using Electrochemiluminescence on Bipolar Electrode
We
suggest an electrochemiluminescence (ECL)-sensing platform driven
by ecofriendly, disposable, and miniaturized reverse electrodialysis
(RED) patches as an electric power source. The flexible RED patches
composed of ion-exchange membranes (IEMs) can produce voltage required
for ECL sensing by simply choosing the appropriate number of IEMs
and the ratio of salt concentrations. We integrate the RED patch with
a bipolar electrode on the microfluidic chip to demonstrate the proof-of-concept,
i.e., glucose detection in the range of 0.5–10 mM by observing
ECL emissions with naked eyes. The miniaturized RED-powered biosensing
system is widely applicable for electrochemical-sensing platforms.
This is expected to be a solution for practical availability of battery-free
electrochemical sensors for disease diagnosis in developing countries
