A detailed description of how it was developed and the experiments performed is available from our paper published in PLoS One at:
a youtube video of how to develop the device is available at:
In our paper we show that the device can perform similar to standard research equipment and can accurately perform cyclic voltammetry to quantify the amount of vitamin C in orange juice. Can function as a single chip glucose meter to measure blood glucose and measure the amount of lead in water down to the 15 ppb level.
More details and command instructions can be found on the github pages for the firmware and GUI. The github pages also list future improvements that are planned.
