Figure Lengend Snippet: ( a ) Microsensor design diagram, consisting of 2 arrays of 7 disk electrodes fabricated in gold and in platinum, and an integrated pRE and CE. Details of the arrangement of the two arrays and corresponding diameter of the electrodes, the distance between them, and the distance between the two arrays. ( b ) A flexible polyimide multi-analyte sensor fabricated on a flexible Kapton ® substrate at a wafer level. ( c ) An individualized multi-analyte sensor.

Article Snippet: Complete profiles were obtained by performing two consecutive measurements, placing the needle across the biofilm with the aid of a micromanipulator resulting in a 14-point profile acquired in 60 s. The novel microsensor performance for biofilm profiling was assessed using DO and pH profiles acquired using a commercial DO microsensor (OXI-25, Unisense, Aarhus, Denmark) and a commercial pH microsensor (PH-25, Unisense, Aarhus, Denmark).
