Microdevice for continuous monitoring of microbial activity. (A) Top view of the device. The dimensions of the chip are 18 mm by 18 mm. (B) Cross-section along the line X-X' in panel A. (C) Dependence of the potential of the ion-selective electrode on NH4+ ion concentration. Potential of Ag/AgCl(1) with respect to Ag/AgCl(2) was measured. Five measurements were made, and averages and standard deviations are shown. Many of the error bars are behind the symbols.

Continuous monitoring of the ammonia removal activity and observation of the morphology of the active sludge. (A) Changes in the NH4+ ion concentration in the medium with or without the active sludge. The response curves in the medium with the active sludge were obtained by three independent experiments. The insets are representative images obtained using confocal reflection microscopy at the indicated times. Each projection shows fields of 140 by 140 by 30 μm3 (depth × width × height). The thickness of each image stack was 0.8 μm. (B) LIVE/DEAD fluorescent staining at 0 and 48 h of culture. Scale bars indicate 40 μm.
