The fabrication of novel superhydrophobic electrodes is described, which have an air–liquid–solid three‐phase interface, where oxygen is sufficient and constant. Oxygen is an effective natural electron acceptor for oxidase, and plays a key role in the development of reliable bioassays. Such an electrode allows detection of glucose concentration, linearly from 50 × 10 −9 m to 156 × 10 −3 m with good sensitivity and accuracy without analyte dilution. This strategy offers a unique route to address the gas‐deficit problem of many reaction systems.
