PreSens' Featured System for O₂ Mapping in the Life Sciences

The Detector Unit DU01 is an imaging technology allowing easy 2D visualization of oxygen distributions in e. g. living, heterogeneous samples. The handheld digital camera records pixel by pixel sensor responses, capturing information of a whole array of sensor points. With VisiSens™ spatial and temporal changes of oxygen can be monitored. The software allows controlling the image recording process, and assists image processing and evaluation. An easy to use camera controlling user interface manages image acquisition and storage. Measurements which belong together can be organized in user defined sessions as separate folders and annotated with a free text comment. Acquired images can be single images or automatically recorded time series.

The SF-RPSu4 for measuring oxygen allows non-invasive mapping of metabolic activities as well as changes over time periods from seconds to months. The fluorescent sensor foil is attached on a living or dead sample surface or a transparent glass or disposable vessel. A sensor film on the foil translates the oxygen content into a light signal. The sensor foil is
available in different sizes and can easily be cut in any desired shape. Read-out is done contactless with the imaging Detector Unit DU01 or the VisiSens TD.

This software allows controlling the image recording process and assists image processing and evaluation. An easy-to-use acquisition module manages image recording and storage. Measurements which belong together can be organized as user defined sessions. Single images or time series measurements can be performed to analyze both spatial and temporal changes in analyte concentration. The software’s evaluation module allows image processing and multiple options for image display. For analysis a number of functions are supplied.
