It’s all part of a larger effort at developing an open Arduino glucometer ... mainly in procuring glucose oxidase, an enzyme that oxidizes glucose. The reaction creates hydrogen peroxide ...

The sensor is the key to the whole thing. The chemistry behind it is simple: an ultrafine gold wire is covered with glucose oxidase, an enzyme derived from the bacteria Penicillium notatum.

was measured at collection by the glucose oxidase method using a portable glucometer (Medisense Precision QID; Abbott Laboratories, Bedford, MA, USA). Visual analogue scale were used to determine ...
