Diagram and application of the portable visual and electrochemical H 2 O 2 sensors. Hydrogen peroxide is crucial in cell metabolism, playing key roles in cell proliferation, differentiation ...

The cell produces electricity through chemical reactions between hydrogen peroxide and aluminum ... the reaction with aluminum quickly formed a thick sludge that hindered the flow of electricity.

Knowing the precise location of hydrogen peroxide within cells could help scientists gain a better understanding of oxidation-reduction reactions taking place there. The sensor was developed by ...

The sensor reveals where in the cell hydrogen peroxide is produced and how the signaling pathways run. The H2O2 sensor (green) in 6 compartments of a Chlamydomonas cell filled by the large chloroplast ...

(Nanowerk News) MIT chemical engineers have built a sensor array that, for the first time, can detect single molecules of hydrogen peroxide emanating from a single living cell. Hydrogen peroxide has ...
