Visualizing Analytes over Large Sample Surfaces

The VisiSens TD images large areas and gathers information on spatial and temporal analyte changes, e. g. in large scale pH and CO2 imaging of root-soil interactions within rhizotrons or when analyzing biogeochemical processes in sediments. It is also well suited for application in sensitive processes, e. g. metabolic activity of living samples or tissue engineering, where O2 gradients over a cross section of a 3D graft can be monitored.

Multi-Sample and Multi-Sensor Read-Out

Large field of views enable analyte value recording in multiple samples simultaneously with free choice of measurement geometry. Even different sensor ranges can be combined. The fluorescent sensor foils can be mounted at the bottom of transparent vessels, plates or vials containing different samples and placed next to each other, e. g. in a small rack. One image taken from the bottom contains the information on analyte concentrations in a group of samples.

Three Different Analytes with one Device

The modular set-up is applicable for imaging oxygen, pH, and CO2 sensor foils with one system and in one field of view. It visualizes spatial and temporal changes of analyte concentrations. The combined information on distributions of several analytes can give valuable insight in metabolic activity or chemical processes inside samples, e. g. when investigating complex processes in cell culture, or tissues, in root systems, or when phenotyping crop plants.

Microscopic Analyte Imaging - TD MIC Configuration

VisiSens TD can be equipped with microscope optics for measuring analyte gradients with very high spatial resolution. The VisiSens TD MIC can be used e.g. to monitor spatial and temporal changes of O2 of cross-sections of multicellular tumor spheroids. The system is compact and fits into an incubator to monitor analyte changes under cell culture conditions over days.
