CO₂ Sensor Foil SF-CD2R

O₂, pH, and CO₂ are key factors for microbial activity and various geochemical processes in sediments. They highly vary locally, e.g. at interfaces or different depths. Spatial and temporal analyte dynamics over long time periods can be visualized. Various regions can be compared within one measurement. VisiSens enables non-invasive 2D-mapping over cross-sections or on sample surfaces. The portable device can be used in lab and field.

O₂, pH and CO₂ play a crucial role in plant and soil processes, e. g. in photosynthesis, respiration, in rhizospheres or in microbiological processes. Metabolic processes can be monitored. This planar optical sensor technique allows non-invasive read-out through glass walls of rhizotrons. Studying metabolic activity of roots and determining the cultivation optimum is important for sustainable agriculture, e. g. for adjustment of water and fertilizer supply.

VisiSens™ enables 2D visualization of important culture parameters inside microfluidic chips. You can continuously monitor in 2D, with high resolution at specific positions or over the whole chip surface in a non-contact readout mode. Detect metabolic hotspots, record time-series, and monitor hypoxia, cellular growth, or O2 supply inside the chip. You can gain new insights on metabolic activity and natural or artificially produced gradients.
