Microsensors
What can Surflay Microsensors quantify?
Surflay's microsensors are modified microparticles, which can quantify various parameters such as:
- pH
- Temperature
- Oxygen amount
- biomolecular interactions (via WhisperSense platform)
No electronic part must be in contact with the sample: changes in microparticles fluorescence intensity are used for analysis. These microsensors are therefore ideal for measurements in smallest spaces:
microfluidics
cellcultures
cellarrays
organ-on-a-chip
Approaches to use microsensors i.e. dye-embedded microparticles
Fluorescence lifetime measurements
are independent of the concentration and size of the size
Intensity-based measurements
require internal fluorescence standards or dual fluorescence in order to eliminate the influence of particle size and sample transparency
Whispering Gallery Modes
only for bioanalysis
In the image, for example, it can be seen that the fluorescence of pH microsensors change with pH.
